Mark Grayson was born to Nolan Grayson, a Viltrumite, and Deborah Grayson, a Human. When Mark was seven years old, Nolan Grayson told him that he was an alien from a different planet and also the hero of Earth. He was told his people, the Viltrumites, are a race of peaceful explorers and that had come to Earth to help mankind.He was also mentioned one day he would develop super powers like Nolan.
Developing PowersEvery single day, he waited for his powers to develop. One day in his senior year of high school, Mark was sitting on the toilet, reading Science Dog, just like he would on any normal day. However, later that day, when Mark was working at his part time job, he hurled a trash bag hundreds of miles into the air and remarked, "it's about time". Next Mark developed flight, which he developed by jumping off his roof. There he spotted three jewel thieves which he decided to stop. His father tried to have a costume made for him; the first one is an outfit that the hero Zandale Randolph ended up wearing when he was Bulletproof. Mark could not decide on his costume so the superhero tailor, Arthur Rosebaum, told him to come back later after he had picked out a name. After protecting a nerd from being bullied, he was sent to the principal's office, where the principal told him that he is not "Invincible." Mark likes the name and takes the name for his superhero identity. 
Being InvincibleTwo months later, Mark meets the Teen Team, a young group of heroes consisting of Robot, Dupli-Kate, Rex Splode and Atom Eve and helped them capture Maulers, two super-strong, super-smart twins. Mark teamed up with his father to battle an alien invasion from a group called the Flaxans.
At school the next day he recognized Atom Eve, a member of the Teen Team.  The two became friends and fought their teacher when they discovered he had been strapping bombs to students and blowing them up in some elaborate scheme for vengeance for the loss of his son and wife that left him. While Omni-Man was out of town, Mark fought Allen the Alien.  Instead of being an evil alien, he was really testing the champions of planets. Unaware of his job, Omni-Man had previously always thought he was evil. After talking with Mark, Allen realized he had gone to the wrong planet for fifteen years and left.

He goes into the house only to discover that his mom and father were sleeping together, and goes to his room. Not long after, Eve flies through Mark's window. She tells Mark her boyfriend, Rex Splode, cheated on her with Dupli-Kate. She then decides that she will quit the Teen Team. He comforts her until Mark's mother interrupts and demands they come downstairs. She lectures the duo on them having a relationship with one another until Omni-Man interrupts to tell Mark that the Guardians of the The Globe are dead. The next day, Mark is at his locker with William and they discuss Mark's secret identity. Their conversation is cut short by the intrusion of a girl giving Mark a slip of envelope.

Mark goes and see's Amber who is happy about what he did and she tells him that she's giving Gary another chance. Mark goes to Eve's house and tells her what happened and they cuddle for a while.
Later, Mark sees Oliver and apologizes to him about not teaching him things, Oliver sees a reflection from the trees and Mark flies to get the orb it blows up in his hand and he says that someone was watching them. Mark goes to Robot to see if he can find out who's spying on him. Mark then goes to Cecil to see if he is the owner of the orb. Cecil tells Mark that it is not him and if he can help track down a fugitive. Though Mark initially refuses, Cecil manages to convince him as he says that the man killed his wife. The fugitive turns out to be the Astounding Wolf-Man. Gary manages to convince Mark that he didn't kill his wife. Mark asks that he come peacefully and he complies. He takes him to Cecil, but Mark has some disagreements with him. Cecil unleashes the Reanimen on the duo, much to Mark's annoyance.  Mark and Wolf-Man manage to destroy a few Reanimen until Mark realizes that they will be overwhelmed. Mark flies him out of the Pentagon and they are ambushed by The Immortal, Darkwing II, Dupli-Kate, Shapesmith, and Black Samson, the members of the Guardians that didn't quit. After fighting more, Mark grows tired of holding back on them and he grabs Immortal's head, swinging his body to knock out the Guardians. They manage to escape and he takes Wolf-Man to his estate. Wolf-Man reveals the murderer to be Zechariah. Mark meets Gary's estate manager and friend, Dunford before taking him back to the Elder Brood.Mark sees Oliver and sees Eve to fight Eve's nemesis, Killcannon. Eve reveals that she started the company Invincible Inc. to make them money. They kiss and cuddle with each other.  Mark meets a costumed hero named Powerplex, who seeks venganances on Invincible for his father's battle with him. Mark attempts to capture him, but he escapes. Next, Mark would arrive on staged kidnapping. Powerplex attacks Mark and accidentally uses his power to kill his wife and son. Mark bearhugs him and he loses his power. Mark would visit him with Powerplex stating that he will find a way to kill Mark.
Invincible WarMark would be laying on Eve's bed and be one of the many various Image Comics heroes to respond to the call of his evil alternate dimension counterparts attacking the world. Mark fights one of his counterparts and it appears they are evenly matched. Mark smashes his fist on his temples and is attacked by the Capes, Inc team, mistaking him to be evil. Afterwards, Mark and Eve head assist Cyberforce in killing another of his counterparts. They are successful, but Eve is severely injured. Mark takes her to a hospital to get medical attention. Cecil interrupts and asks for help. Mark refuses, stating that Eve needs him. Cecil pleads, but Mark tells Cecil that he doesn't care and that he has every hero working on this. Mark, Oliver, and Zandale find out that Angstrom Levy is behind the incident. Mark also realizes that it was Angstrom that was spying on him. Mark is knocked back several of his orbs. He crushes one and grabs Angstrom's throat. Oliver insist that Mark kill Angstrom. After a long pause, he decides to go through with it. Angstrom knocks him back again and prepare to escape. Before the portal can close, Mark rips off Angstrom forearm. After four days, Mark looks on at the carnage caused worldwide by his counterparts. 
Invincible War: The AftermathInvincible visits Eve in the hospital often while the rest of the super powered community cleans up after the war. Invincible later joins in but blames himself for much of the death and destruction, but he isn't the only one. Many of the human populace view him as the cause of the chaos. Powerplex (who escaped during the chaos, and then chose to help clean up) even attacks him when he goes to the clean up and Badrock has to hold him down and take him back to custody. Later Cecil brings Mark together with Robot, Brit, Black Samson, and Donald Ferguson explaining that Darkwing and Rex are dead, and the Immortal and Kate have quit to have a family. So a new Guardian of the Globe is needed and Mark should be the leader, but Mark is uneasy and still doesn't trust Cecil, so he leaves. After some more self-loathing, a Viltrumite named Conquest shows up to remind Mark of his job of taking over Earth, but Mark is somewhat glad to see him as he needs to hit something. When the duo collided, buildings were shattered and their natural power caused a shockwave. 
The duo charge into each other with Conquest overpowering him. Mark attacks him, and Conquest is amused by his effort. Mark manages to land a few blows, but Conquest gets serious and lands a blow himself, bruising Mark's eye. The duo moves at such fast speeds, Oliver is unable to keep up with them. Mark asks Conquest to listen, but Conquest refuses. Oliver tries to help, but Mark shoves him away, hoping Oliver won't get killed. Mark lands a few blows, but Conquest catches his punch. Conquest slings Mark around, but Oliver intervenes. Mark witnesses Conquest break Oliver's arm and his attempt to rip Oliver in half.Mark charges into him and Conquest sends him flying across a ship at sea. Eve wakes up and rushes to help Mark. Mark attempts to move Conquest, but he breaks Mark's leg. Eve puts Conquest in an imprisoning bubble, but he breaks out. Conquest easily overwhelms Eve and impales her. Everyone believes she is dead. Conquest then thanks Mark for the battle they are having. In his anger, Mark promises to kill Conquest. They continue to fight despite Mark's body having been broken and his excessive bleeding. His rage allows him to turn the tide as he destroys Conquest's robotic arm, but breaks his in the process.
Eve recovers from her injuries and fires a massive energy beam at Conquest that burns all the skin off his body. Mark continues to fight him as the Conquest isn't done yet. In the end, Mark headbutts Conquest over and over again until his skull is crushed, apparently killing him. Invincible then collapses to the ground due to his injuries as the heroes show up to help him. Mark awakens in the Pentagon hospital with Eve by his side. The two reconcile with Mark noticing that Eve's breasts have gotten larger, leading to an intimate moment between them. He is extremely upset because he thought that he lost her. This moment is quickly interrupted by Debbie Grayson. Later on, Invincible joins the other heroes at the funeral for Rex Splode. Robot takes on Rex's name. Afterwards, Mark goes to see Oliver in the hospital. Mark then reveals a shocking revelation he had during his fight with Conquest: in order to truly protect Earth, Mark must kill every villain he encounters from now on.
Invincible and the rest of the superhero committee seem to be finishing reconstructing the cities of the world. Invincible then gets attack by a new villain called Dinosaurus. He then proceeds to rant on how Invincible could be allowing non super-powered people to clean up the damage, which would grant more jobs and help the economy, not to mention the amount of time they would be employed compared to the fast clean-up Mark is doing. After a quick fight Invincible is just about to kill Dinosaurus, but just then the Guardians Of The Globe arrive. Robot then asks Invincible if he was really going to kill Dinosaurus.
Later at Eve's house, Mark explains to Eve what happened the city. Then they have dinner with Eve's parents. After a long and awkward dinner Mark and Eve talk about the prison meeting they have the other day. After the prison meeting, in which Mark agrees to not charge the prison for 3 months, they both meet an older Oliver flying around with a new costume now calling himself "Young Omni-Man". Oliver goes on and tells them that there's no one on the house so they can have some fun.. Mark knocks on the bathroom door and she tells him go away for some reason.The Sequids commence their attack lead by Rus Livingston in Texas. Mark answers the call first from a nuclear plant and heads off before his mother can tell him what's happening in the city. Mark and Eve face an alien named Universa. She tells them that she is on earth for the planet's energy and will not leave until she gets it. After a difficult fight, Invincible manages to get her staff, which is revealed to be the source of her powers. Invincible gets shocked since he can't wield the staff. Atom Eve sucker punches her and rushes to see if Invincible is okay. Right then Cecil enters the room and tells Invincible that the Sequids are back. He then heads off to fight the invasion along with other heroes. The battle seems hopeless, leaving Invincible with only one choice: to kill him. After Invincible kills the possessed he quickly leaves the scene and feels guilt over for what he's done. He returns to his house to tell Eve what he did and how bad he feels and gets cut by Cecil, who ask Mark to come with him to the base. 
Cecil tell Mark how he feels about the situation at hand. Cecil tells Mark about how once bad people can be turned good if given a second chance, using D.A. Sinclair as an example. Later on, Mark is helping Titan battle his old master, Mister Liu (who was the same dragon they fought before), but in the process Mark almost kills Titan.Mark then visits Art and tells him about the things that happened recently in his life, like watching Eve die and him killing. Telling him that the black and blue costume sometimes feels like a curse and that he can't even look at himself anymore. Art tell Mark that he is a good man and tell him that he doesn't have to wear that costume anymore and gives an updated version of his old costume. Mark then meets Eve at his house and asks her if she wants to go to have dinner. Right there Mark's father, Nolan arrives before him. With Allen accompanying him, Nolan tells Mark that he is need and the time of war is upon them.
Mark tells Eve what has happened so far and what he knows about the Viltrumites. He also tells Eve about how he is scared of what the war will make of him. It would seem that it was around this time that Mark helped the Dynamo 5 fight the aliens that came to Earth looking for Earth's champions.
In the middle of a Flaxan invasion, Invincible gets a call from Eve, telling him to rush over to a shopping mall. Invincible declines, saying that he is busy and telling her to see if Oliver can take care of that instead. Later on, in Mark's house, him and Oliver are discussing whether they should bring Oliver or not, but Oliver was being persistent and told Mark that he might need his help. Later on their father agrees into bringing Oliver with them. Meanwhile, Nolan reunites with Debbie.
The Viltrumite War
After an emotional goodbye to Eve, Mark, along with his father, his brother Oliver and now the recruited Tech Jacket (Zack Thompson), they all head off to space with Allen to meet the Coalition of Planets. It was on the way to meet up with the coalition that they get attack by the fully recovered and still alive Conquest, Lucan and an unnamed Viltrumite from before. They all fight, and in the middle of the fight Oliver loses his breath and is forced to find the nearest planet to catch some air. Conquest follows him and just about as he is to attack Oliver, Mark cuts him off and the 2 of them continue their fight.After a tough battle, Mark finally manages to kill Conquest once and for all, but it also left him in the verge of death. It is right there where his father and his brother find him. Omni-Man tells Oliver that Mark will recover, but it will take a couple of months before he can be fine again. Meanwhile, The Viltrumite War finally started. After some months, Mark finally regain consciousness and asked his father about what happened and if he was the one to have killed Conquest. Nolan corrects Mark by telling him that it was Mark that have been the one that killed Conquest. They all head off to assist and stop a Viltrumite attack on Talescria. It is revealed that there is a traitor among them.
Thaedus gets everyone ready to fight the Viltrumites on their home planet, Viltrum. They all head out to space, finally reaching the Viltrumite planet. Thaedus then gets slashed by a female Viltrumite, Thula, but Battle Beast (who has made a major shift from being Machine Head's bodyguard to a good, anti-Vilturmite warrior) cuts in and begins to fight her. Emperor Thragg arrives with some Viltrumites, and just then Space Racer (another Coalition fighter) arrives with Ragnars, creatures that can battle the Viltrumites. Mark and Oliver fight some Viltrumites, until Mark finally fights Thragg, only to be pushed aside. Oliver insults Thragg and proceeds to punch him. Thragg grabs Oliver's hand and breaks his jaw while ripping his arm off. This angers Invincible and he proceeds to fight Thragg, only to be punched back later. Along with his father and Thaedus, the three of them charge to the center of the Viltrumite planet along with a blast from the Spacer Racer. With the blast from combining with the three charging, the planet explodes. Mark then heads to find Oliver's body, crying.
After killing Thaedus, Thragg charges for Mark first. Mark kicks him back and punches him, with no effect on him. Thragg then continues to pummel him while telling him that he had taken away his history, heritage, etc. Nolan intervenes, only to be overpowered as well. Thragg head butts him,only to be stopped by Battle Beast. After Thragg throws Battle Beast away from the battle, Thragg continues his assault on Mark.Omni-Man kicks Thraggs hand's off Mark so he can get away. Thragg catches up to him and smashes his fist onto Mark face. Thragg grabs Mark by his neck, only for Nolan to try to intervene. Thragg impales Omni-Man and proceeds to talk to Invincible. Kregg, another Viltrumite who is spectating, asks why Thragg hasn't killed Mark and his father yet. Thragg has decided to spare Mark and Nolan. Mark and Nolan are later rescued by a Coalition ship and taken back to Talescria. Mark wakes up in Talescria only to find Allen watching over him. Allen states that he was worried about Mark due to his severe injuries. Mark asks Allen what is he wearing, and Allen says that he is now the leader of the Coalition of Planets since Thaedus has died. Allen tells Mark that he was out for two weeks and shows Mark to his father. He also sees that Oliver is recovering from the injuries (being given a new jaw and arm.) induced by Thragg.
He proceeds to talk to his father about Oliver and finds out that he should be out of a coma in a few days. When Allen gets his report from Tech Jacket on previously Viltrumite occupied planets, he begins to panic. Allen had told Invincible that there was no Viltrumite activity. Mark goes on to say that the Viltrumites wouldn't have let him live if they didn't want to hurt him. He, then, puts the pieces together and realizes they are on Earth.  Worried about what's happening on Earth, Mark and Omni-Man head there, and Invincible thinks about what the Viltrumites might do to Earth. Omni-Man tries to comfort his son, only to be awkwardly interrupted by Tech Jacket. Tech Jacket leaves, and then Mark leaves the ship to fly to Earth once the ship gets close enough.
Flying all over the Earth, he doesn't see the Viltrumites. Omni-Man asks Mark to look over and Thragg appears before them. Mark proceeds to attack him, and only for Thragg to grab his neck and throw him. Thragg begins to try and negotiate with Mark. Thragg goes on that he wants a truce due to there only being 37 pure-blooded Viltrumites alive in the universe. He goes on to say that they will occupy the planet, but hide among the humans to interbreed. He states that Earth is the perfect place to replenish their ranks due to Human DNA being similar a Viltrumites'. Mark rebuffs by saying that the Viltrumites will get stronger next time they fight. Thragg reprimands him and saying that fighting today will result in catastrophic losses. Mark isfurious, but agrees to it (thinking back on what could happen if he said no). Thragg commends Mark and tells him how him and Nolan may be the reason the Viltrum Empire prospers again. Tech Jacket arrives to the scene only for him to be told that the war is over.
Mark flies to his house with his father, to surprise his mother. She greets him with a hug. Asking where Oliver is, Omni-Man states that he's injured but alive. Debbie tells Mark to go see Eve. Mark flies to Eve's house and opens her window. Eve, in tears, warns him not to come closer due to her weight gain over the 10 months. Mark embraces her anyway to tell her that he loves her. He lays in her bed to discuss what has been happening while they were gone. She tells Mark that he has been keeping the Invincible Inc. business running by using Bulletproof.
Mark flies off the next day and proclaims that though the war may be over, they didn't win. 
Post Viltrumite WarInvincible later goes to visit Art at the Tailor Shoppe. Invincible asks to get his old costume back. He flies back to the Wilkins Residence to talk with Eve. They begin to converse and they are interrupted by Invincible Inc. calling. Invincible reports and fights several of his past villains. He goes back to his house to see Eve talking with his mom, and wonders what they are talking about. Samantha goes on to say that she thought he was finished with the bank job and popped up to see his mom. Mark, confused by this, wonders why. She states that while he was gone, she bonded with his mother. He leaves to look for his father. Next, Invincible and Atom Eve fly to Dupli-Kate and the Immortal's house, who were married years ago. There they are greeted cheerfully by Kate, the Immortal, and their twins. From there, they have dinner with the group exchanging stories to one another. After dinner is over, Eve goes to help Kate with her twins' baths. Seeing the happy babies, Eve runs out of the house crying. Mark goes after her. He asks why she is crying, and she finally reveals that she had an abortion when he was gone. Mark, shocked at the revelation of her being pregnant before, begins to cry. He embraces her with him apologizing for leaving her alone all that time. 
Mark and Eve arrive at his house, only to see his mother and his father about, together. They tell Mark that they are back together after the events of Omni-Man abandoning his post. They also inform him that they are going to Talescria to see Oliver and work on their relationship. As the spaceship leaves, Mark and Eve go outside to talk. After they are finished, they climb into Mark's bed. Mark wakes up and wanted to talk about what happened that night. Eve drops the subject and they go back to bed. Mark goes to visit his old friend, William Clockwell over at Upstate University. Hoping to check up with his old friend, they discuss things. Rick Sheridan, William's roommate comes in, happy to see Mark. He dropped off dinner on the counter and gives William a kiss on the cheek. Mark is shocked and asks William if he is homosexual.
William reveals his sexual orientation to Mark, confused at first, because he assumed that Mark knew. Mark goes on another job and to stop Dinosaurus again. However, he is unsuccessful at stopping Dinosaurus this time, and Las Vegas is turn into glass by several hydrogen bombs. Numerous lives are also lost. He looks into his reflection and wallows in sorrow for not being able to stop him. Later, he would go with Eve and stop a bank robbery. After the event, Powerplex goes to stop Mark but Mark uses his words to calm him down. Powerplex cries after he realizes he killed his wife. Mark comforts him afterwards and he goes home after talking with Cecil. Afterward, he would arrive home to Eve and talk about how things are getting worse. Mark would visit Universa in prison and negotiate with her. He manages to get her released. She gets energy for her planet, and she thanks Mark for being mericful before returning to her planet. Cecil would later reveal that Sinclair has been making Reanimen of the deceased counterparts. Mark stated that this is okay for him to do, surprising Cecil. He leaves the White Room and would go to Monster Girl and Robot's returning party, who were stranded for a time in the Flaxan dimension.Mark notices that things between Monster Girl and Rex aren't okay. The next day, Mark head to stop Tether Tyrant, but the Guardians have already taken care of it. Magmaniac was killed earlier. Mark would later go to where Las Vegas used to be, and Cecil told him about how Las Vegas is now a large solar panel. Seeing that some good came out of it, Mark realizes that Dinosaurus was right. He would next talk to Eve to ask her if he would still love her if he were to do something rash. Eve reassures him, and Mark goes to break Dinosaurus out of the Pentagon. He meets a wave of Reanimen, but easily escape with Dinosaurus. They head to his secret base and begin planning their next move. 
Saving the World
Omnipotus returns and defeats the Guardians. Mark and Dinosaurus head to the scene and Dinosaurus crushes his head. The Guardians recover and attempt to arrest Dinosaurus and Mark. Mark arrives home and Eve realizes what he had done. Cecil interrupts and asks Mark to talk with him. Cecil begins to talk about how he was impressed with Mark, but he took a step in the wrong direction. Cecil gets a transmission and asks Mark to go to space to see Allen. He notices Oliver with him and asks why they are here. He also notices that his father isn't with him. Allen then tells Mark of his plan to release the Scourge Virus into the atmosphere. Mark becomes angry and asks how similar this is to how the Viltrumites did to the Unopans.
Allen gives his explanation, but Mark isn't convinced. They commence battle until Thragg interrupts to aid Mark, much to his shock. Allen becomes startled and Thragg informs him that he knows about their plan. Allen reaches for the virus dispenser and Thragg notes that he could kill him before the virus could have effect. Thragg offers a truce and Allen reluctantly accepts. Their conversation is interrupted by the Guardians appearing. They attempt to capture Mark again but to no avail. While distracted by the battle, Oliver uses to the time to grab the virus dispenser. Mark notices him flying to Earth and attempts to stop him. They get into a brief scuffle and argument with Oliver arguing that the human loss is lower than a galaxy loss. The duo get into a tug-of-war and Oliver accidentally dispenses the virus into Mark's face. Allen rushes to catch him.
Allen tells Mark not to worry because the virus is meant to pass on from person to person. Mark starts to think that he feels ok. Allen notices that Mark's eyes and nose is bleeding. Mark would be quarantined in the Viltrumite Warship. Mark would be kept there until Thragg attempts to kill him. Dinosaurus intervenes, and is severely injured by Thragg. Dinosaurus grabs Mark and uses an escape pod to leave.Mark wakes up, noticing Dinosaurus saved him. Dinosaurus reverts to human form and Mark compares him to Oliver. Mark says that he lacks empathy for humans, but unlike Oliver he is "pure intelligence". Mark learns that Thragg attempted to kill him. Bulletproof arrives to save Mark, believing him to have been kidnapped by Dinosaurus. Eve arrives and tells Mark that she sent Bulletproof. Oliver and Allen arrive to the scene and attempt to fight Dinosaurus. Mark attempts to stop their assault and punches Allen. The result of breaks Mark's arm, making him realize that the Scourge Virus has weakened him. Mark is taken The Pentagon and has surgery on his arm. Cecil explains to Mark that the virus has weakened his invulnerability and that he may never get his powers back again. Mark states that this may take some getting used to. Eve has to protect him in a force field while the Guardians take down Octoboss. He goes home, feeling helpless, noting that he may never be Invincible again. A Flaxan invasion of London occurs and Mark asks Eve if he can go. Eve says no, citing that he will be unprotected. After the battle gets intense, Eve decides to go to London herself. Mark watches the news and becomes frustrated, kicking a table. Oliver and Allen arrive to Mark's house, and Mark displaces his frustration onto the duo. Mark apologizes after the duo give their reasons and Oliver asks to speak with Mark in private. Oliver apologizes to Mark for infecting him and they hug. Eve arrives, says goodbye to the duo, and asks Mark if they want to have sex. Mark says yes, though mentioning that not having his powers don't make it the same. Afterwards, Mark begins to feel worthless because his powers desensitize him. Mark would later go to a comic book signing for Science Dog. That night, Mark and Eve begin to have an intimate moment. As they progress, Mark discovers that his powers are back. 
The Death Of Everyone
After discovering that his powers are back, Mark and Bulletproof have a conversation about Bulletproof helping Invincible Inc. Mark allows Bulletproof to keep the Invincible costume and flies off to Dinosaurus's base in his other one. Dinosaurus says that while Mark lost his powers, Dinosaurus had a plan to stop the effects of global warming and famine. He informs Mark that he has placed a bomb in Los Angeles. Mark rushes to Los Angeles to find the bombs. He calls Cecil so that he have the Guardians assist him. After the Guardians arrive, Dinosaurus arrives to the scene and gets into a brief argument with Mark. Dinosaurus mocks Mark for saving Los Angeles when billions matter more. Dinosaurus also reveals to Mark that Los Angeles was a distraction and that he placed a bomb in Greenland, which subsequently detonates. Mark flies up to the air and sees that the effect flooded many major cities around the world.Mark becomes angry and grabs Dinosaurus to crash him into the ground. Dinosaurus attempts to reasons to him but to no avail. Mark continues to attack him until Dinosaurus launches him. Dinosaurus tries to get Mark to see the "bigger picture" but Mark punches him. He demands Dinosaurus to hear his side and declares that Dinosaurus must die. Dinosaurus defeats Mark and declares that he must die instead. Dinosaurus supposedly kills him by smashing his head in, and dismembers him for the world to see. However, it is revealed that Dinosaurus put Mark in a coma, utilizing Mark's vulnerable ears, and instead killed a depowered, hastily made clone of Mark. Mark explains that though Dinosaurus is getting rid of a problem, he caused more harm than good. Dinosaurus realizes that Mark is right and frees him from his coma.
Dinosaurus stated that he developed a god-complex and that he was only trying to save people. Mark asks Dinosaurus for help, but he refuses. Dinosaurus says that there will be some good that comes from his flooding the cities. Hoping to atone for his mistakes, Dinosaurus asks Mark to kill him. Mark walks out of Dinosaurus's base with blood on his clothes, signifying that Dinosaurus is dead. Cecil arrives to see Mark. Cecil reveals the casuality rate and Mark asks Cecil to see Eve before he goes to prison. Cecil instead gives Mark a chance to work for him again. He gives Mark the earpiece and Mark heads home to see Eve. He notices his parents are there too and they chat, relieved to hear that Mark isn't dead. Mark and Eve go to talk in private at his home roof. Mark reveals that he is working for Cecil again, much to Eve's shock. Mark goes on to say that he was reckless and he shouldn't make the same mistakes. Eve reveals to Mark that she is pregnant.
Mark is initially in shock but states that he will stand with whatever decision Eve makes. Not wanting to get an abortion again, Eve decides to keep the child. Mark, excited to be a father, embraces her. They find Nolan and Debra kissing one another. The next day, Mark and Eve head to help the Guardians clear debris. Robot asks Mark why he's here due to his apparent death. Robot's drone attacks Mark until Cecil intervenes to take Mark to the Pentagon. Cecil apologizes and Mark informs Cecil that Nolan is back on Earth. Mark also mentions that he will be a father and asks for his assistance. Mark finally asks Cecil to see Dinosaurus to make sure he's dead, noting what Cecil did with Conquest. Cecil provides the corpse, which Mark identifies as true due to a special marking he placed on it. Mark heads home and asks that a superhero consultant named Sherry to check on Eve's fetus. Reluctant at first, Eve allows her to do it. Sherry uses her X-Ray vision and sees that the fetus is fine. However, she states that Eve must not use her powers because it could eventually kill her fetus.
Mark would later attend his father's inauguration as Emperor of Viltrum, after the exile of Thragg, and the discovery that Nolan's father was the original Viltrumite Emperor, Lord Argall. Mark tells Eve about it. Eve uses her powers to make a ring and even before Mark asks her to marry him, she says she will. After they have sex, Eve realizes that her making the ring may have harmed the fetus. Mark calls Sherry and she reveals that the fetus is alive. However, her previous statement was "playing it safe" and that she must not ever use her powers. She reveals that the calories burned using her powers can feed on the fetus in order to give her body energy. While Eve was away, Mark would battle Mauler again, believing him to be dead. After he and the Guardians defeat Mauler, he heads home to discover that Angstrom Levy has taken his fiancee taken hostage.He rushes to Levy and is sent to the same dimension that Mark supposedly killed him in. He watches in shock and realizes that an alternate version of him has resorted to cannibalism to survive. Not recognizing him at first, the alternate Mark asks him to join in. He then realizes who Mark is and attempts to eat him. Mark attempts to reason with the cannibal Sinister Mark, but to no avail. Another version of Mark, "Mohawk Mark", arrives and offers assistance. Mark assists his alternate version in taking out the cannibalistic one. Mark returns back to his reality and Mohawk Mark follows suit. Mohawk Mark charges into Levy, but Angstrom reveals that he has had a change of heart after talking to Eve. Levy also reveals that many versions of Mark are evil and it should scare him. He surrenders and opens a portal back to the alternate Mark's home reality. Mohawk Mark quickly takes Angstrom with him and the portal closes. Mark asks Rex to scan the room to figure which frequency the dimension is, hoping to find out what happened to Levy.  The next day, Mark stops a burglary and asks Robot to keep him posted on the Levy situation. Mark arrives home to notice that his old room is being converted into a room for his child by Eve. Mark would then be visited by his father, and they head to the moon. Nolan reveals that he has exiled Thragg and that he worries more than ever about his family. Mark also reveals to him that Eve is pregnant with his child. Mark and Eve go to the moon base, now the home of Mark's parents. Eve mistakenly reveals that she is pregnant after Nolan asks Mark if she going to tell his wife. The four have dinner and Mark boasts about his newfound strength. After going back and forth, Mark and Nolan arm wrestle. Mark is able to hold his own for a while until he would notice Anissa watching outside. Mark heads into a Magmanite invasion lead by a newly powered Doctor Seismic and Volcanikka. He attempts to kill the giant monster but is stopped by Doctor Seismic. Doctor Sesmic attempts to incinerate Mark but only burns his costume. He throws Doctor Seismic off of him and rushes to the monster, only for it be killed. Mark flies to the sky and discovers that Anissa had slain it. Curious to know why, Mark cites that he noticed her watching his father and him arm wrestle. Anissa rebuffs and says that she was watching Mark instead of Nolan. She kisses Mark, much to his confusion, and flies off. Mark goes home and Eve pleads with Mark not to go to after Angstrom. That night, when Even is asleep, Mark gets a call from Robot stating that he has found a way to get to the alternate dimension Angstrom is in. Mark and Eve head to the space station Rex is at. After a brief argument with Eve, Robot and Mark head to the dimension.
On their way to the alternate Earth, they encounter an alternate version of Conquest. Conquest demands that the duo come with him or he will kill them. They comply and head to the Pentagon to see the alternate reality Mark that took Angstrom. He gets Mark to go with him and the alternate Mark reveals that he is torturing Angstrom in order to get him to expand the Viltrum Empire. Mohawk Mark says that Mark is one of the few good Marks, and suddenly Robot admits a pulse onto the duo, causing them intense pain. It is the same pulse that was used on Mark before. Robot kills the scientists and fires a grenade into Mohawk Mark's mouth, killing him. Robot then kills Angstrom to ensure that Mark has no way of returning back to his home dimension. Robot tells Mark that he doesn't want to kill him and instead decides to leave him stranded there. 
Stranded In Another DimensionSeeing the carnage and an alternate Kregg coming, Mark thinks of a plan. He switches costumes with the dead version of him and rips out his hair to make it look as if he is Mohawk Mark. Mark lies to Kregg and asks that he handle the Emperor duties until he finds a way to get out. He flies to the Teen Team base to see if an alternate version of Robot is there.
At first, the alternate Robot threatens to kill him, but Mark talks him down. He states that he is from another reality and wants his help. Alternate Robot reveals that Mark had killed Eve in his reality. Afterwards, Mark has Robot come into a lab with him to find a way to get him back home. Reluctant at first, Robot offers his assistance despite risking his death. Mark goes out to search for the Mauler twins and finds one that is still alive. Although they had a brief confrontation, Mark reveals to him that he is from another reality and thus didn't kill Mauler's brother. Mauler offers his help and they begin building a cloning machine so Robot could pose as the new Mark.
Mark asks the Viltrumites to not attempt to rescue him so he could cover Robot and Mauler aiding him. Months later, they finish the project and begin the cloning process. The Viltrumites unleash an alternate version of Monster Girl, who is physiologically an infant, because Robot never helped her dilemma. She transforms into an even larger monster, and Mark heads back home.
Mark arrives back at the old Teen Team base and flies back to his house. He arrives and is relieved to see Eve alive. Mark asks where Rudolph Conners is and what he told her. Eve replies that he said Mark was dead. Mark asks if she knows where Robot is, with no response again. Mark then asks about Eve’s well-being. Eve states that she almost lost their child and that Mark being gone for six months caused her to not want to eat. Eve tells Mark what Robot said and Mark states that he lied. Not caring, Eve goes on to explain that raising her child without him was be the best option.Mark notices that Eve isn’t wearing her ring and Eve says that she cannot allow a child to live through a life, not knowing when or if its father is coming back. Mark attempts to explain to her that she was right about Angstrom, but Eve refuses to listen. Eve tells Mark that their relationship is over, much to Mark's sorrow. Mark begins to cry and Eve explains that his unreliability is the reason why. Mark asks that Eve leave to where she can’t be found by Robot. He flies out of his house, crying and declaring his love for her. He is interrupted by the appearance of Anissa. She asks Mark where he has been, who does not want to talk to her.
Anissa tells Mark of the Viltrumite mission and how she isn’t performing on her part. Mark attempts to leave but Anissa stops him, saying that she refuses to mate with humans, but will settle for Mark because he has Viltrumite DNA. Mark refuses her, flying away, but Anissa stops Mark by attacking him. Mark, not wanting to fight, asks her to leave him be. Anissa says she doesn’t want to fight either, but cannot stall the mission any longer. Anissa attempts to seduce Mark, but he refuses her. Losing her patience, Anissa headbutts Mark and continues to assault him. Mark asks her to leave him alone, but she ignores him. Mark attacks Anissa, hoping to sway her away. However, she is enjoying their conflict. Anissa catches Mark’s next punch, complimenting his strength. Anissa uses her superior strength and they land on unknown farm, with Anissa on top of Mark. She holds Mark’s arms back, demanding that he stop resisting. Mark attacks her, demanding that she leave him alone. Anissa puts her elbow on neck, saying that she doesn’t care.Mark attempts to push Anissa off of him, but is unable to. Anissa tears off both of their costumes. Anissa then rapes Mark. Traumatized by the event, he begins to cry. Anissa demands that Mark “man up” and says that it will probably take a few more times, implying she will come back. She flies away, leaving a traumatized Mark to reflect. Mark receives some clothes from a farmer and flies off to the Pentagon. Mark asks Cecil about Robot’s location.
Cecil reveals that they don’t know and questions Mark. Robot arrives, and attempts to lie to Cecil, saying that Mark was killed. However, he sees through it and Robot transmits a pulse to de-power Mark for a bit. Robot slits Cecil’s throat and crushes his skull. Mark, despite being in pain, destroys Robot’s drone. Robot asks Mark to come to Mark's house. Mark flies there and notices that Robot's new drone is with Eve. Mark attempts to attack Robot’s drone, but is blocked by another pulse.
Mark hits him, which only hurts himself in the process. Robot dismembers Eve’s leg, after attaching a latch onto her. Mark bandages her leg and Robot fires a grenade. Mark escapes just in time to save Eve. Eve, after destroying Robot's drone, creates a force field to protect her from the vacuum of space, and the duo head to the Viltrumite Warship. Eve tells Mark worriedly that their baby might be in trouble now, and becomes unconscious. Mark asks his father to help him and Eve is put into surgery. Meanwhile, Rex kills multiple superhumans and takes over the world.
All Hail Rex
Mark falls asleep, and awakens to see Sherry holding his newborn daughter. He grabs his daugther and holds her, crying. Sherry tells Mark that Eve won’t have a human leg anymore. Mark says that he is happy that she is alive. After her surgery is over, Mark heads to see Eve, who asks to hold their child. He leaves to talk to his father and learns that Monster Girl is in surgery after attempting to fight Robot. Their conversation is interrupted by Anissa reporting to Nolan about Robot’s drone. Mark shakes at the sight of her, and she whispers to him that she “missed him”. Mark offers to help his father fight Rex, but Nolan suggests that he tend to Eve. Eve, having lost the weight gain immediately after childbirth, uses her power and rebuilds Mark's Invincible costume, and tells him to save the world.
Mark rushes to Robot’s drone, but stops and wonders why the Viltrumites aren’t attacking it. Anissa offers to help him up, but Mark smacks her hand away. Nolan intervenes and tells Mark that the Viltrumites have negotiated with Rex. Mark rushes to the Pentagon and confronts Rex in person. Rex attempts to reason with Mark for a long while. Rex finally gets through to Mark, who heads back to the moon. Mark informs Eve that Rex has actually won.
Mark heads to William and Rick’s dorm, and William tells Mark all the good things that have been happening since Rex’s takeover. After, Mark takes Eve to her parents' house and they have dinner with them. They meet Eve's daughter. The next day, Mark and Eve go to funerals of Black Samson, Knock-Out and Kid Thor, and Cecil’s. Mark flies in the sky, only to be interrupted by the Immortal. The Immortal asks for Mark’s help in stopping Rex. Mark goes on to say that Rex is doing the right thing, logically, no matter how evil it may seem. The Immortal points out that the world doesn’t make sense, it never has, and it needs to stay that way. Touched by his word, Mark asks his father for help again. Nolan refuses again. Mark looks behind him and notices that Anissa is there. He grabs her throat and tells her to back off. Anissa tells him that she is enjoying this and says that it makes her want to “speed up their next encounter.”
Mark lets her go and goes back to his house. Mark starts to daydream, but Eve gets his attention. He realizes that he won’t be able stand aside and let Rex take over, but also takes into account that he is a father now.

Being a Parent
Mark, Eve, and Terra arrive in Talescria. The trio is greeted by Allen, with two bodyguards beside him. Allen gets a closer look at Terra, commenting that she is cute. Terra punches Allen's eye and his bodyguards attempt to intervene. Eve puts up a force-field, but Allen stops his men from attacking first. Allen remembers that he has duty to attend to, and that someone else wants to meet them. Oliver arrives on the scene with a new appearance, and being much older. Oliver offers to cook dinner with his girlfriend. Allen leads Eve and Mark to their new house, and then leaves to resume his duties. While Eve changes Terra's diaper, Mark goes to ask Eve where to put her clothes. Afterwards, the two fall asleep with Terra. Eve wakes up to put Terra in her crib and attempts to get intimate with Mark. Mark panics and flies into a wall. Eve asks Mark if there's something wrong, only to be interrupted by the arrival of Oliver and his girlfriend, Haluma. They bring groceries in and Eve directs to the kitchen.
Mark and Oliver go to talk about Haluma. Oliver comments to Mark that her lobster-like appearance may seem strange, but that's what he's attracted to. Mark comments that he's happy for him. The four sit down for dinner and Oliver asks Mark to try the food. Mark takes a bite, surprised at how much he enjoys it. After dinner, an exhausted Mark falls asleep on the couch. The next morning, Mark goes to the bathroom to defecate what he ate. Eve knocks on the door and asks him if he's okay. Mark attempts to flush, but to no avail. Eve arrives with Mark, believing he broke something. Eve finds a button on the side and flushes it down. Mark heads to a window and Eve follows him. She holds his hand and they kiss. As they get intimate, Mark begins to cry, and a worried Eve wonders what's wrong again. Mark sits down and, with enough persistence from Eve, finally reveals that Anissa raped him. Mark goes on to say that it happened after Eve broke up with him.Eve attempts to comfort him but Mark pushes her away. Mark goes on to say that he refused her, and him holding back may have allowed it to happen. Mark ponders on the question and Eve begins to cry. Eve noticed that Terra had stopped breathing. Mark and Eve rushed her to a nearby hospital. They arrive and are asked to sign paperwork. The doctor arrives and scans Terra, asking what species she is. Eve tells her that she is a Human/Viltrumite hybrid, which makes the doctor want to refuse her treatment. Mark demands that he does it anyone, and the scared doctor complies. They ask to go with him, but the doctor insists that they'll only be in the way. They wait in the lobby and Oliver arrives with Haluma.
Mark begins blaming Haluma's food. After a heated discussion as to the source of Terra's illness, Mark began crying in grief over the thought of losing her. Eve comes back from the emergency room to tell Mark that Terra is fine. The doctor tells them that the food she ingested caused her to be oxidized and since Viltrumites can hold their breath a long time, she didn't need to breathe. However, the doctor said that her not breathing caused the oxygen to not rush to her brain. Mark goes to Allen's office, who asks him if his superhero duties are over. Mark says yes, but Allen says that he must make some form of payments, since it exhausts Coalition funds. Allen remarks that he would let him stay here free of charge, were it up to him. Allen offers him a job as a spy for the Coalition. Mark is hesitant, but accepts. He arrives home and finds Eve cooking. Eve tells him that she must eat Geledarian food in order for Terra to be healthy, since the similarities are close to human food. After cleaning and eating, Eve finally talks to Mark about the Anissa situation. Eve asks that Mark doesn't blame himself about it and that they'll work through it together. Eve attempts to kiss Mark, but Mark backs away. They hear a knock on the door and Allen reveals that he doesn't think Battle Beast will win and ask Mark to finish Thragg off while he's weakened. 
Mark and Oliver examine the aftermath of the battle between Thragg and Battle Beast on Thraxa. They cannot find either of them, but a local informs them that the flesh of Battle Beast was burned in a massive celebration. They return to their ship and later find Thresha, Battle Beast's girlfriend, and Space Racer floating around in a debris field in space. The two are given medical attention. Thresha breaks out of her stasis field and attacks the members on the ship, in a fit of rage over Battle Beast's death, but is eventually subdued. Mark returns home where he discusses the recent events with Eve. As the two get ready for bed, Eve claims that she wants to do more than just go to bed. She tells him that it's okay if he doesn't want to, but Mark says he wants to try.
Mark is awoken by Terra crying, and he goes to care for her. They spend a lot of time together, with Mark doing fatherly things like feeding her, getting thrown up on, playing with her, and reading to her. Mark tells him how much he cares for her, and that she is the best thing that has ever happened to him. He also tells her that if she comes home drunk, or destroys their vehicle that he will scold her, because that's his job. Eve wakes up to see Mark and Terra having some father-daughter time. Mark suggests they go out to eat and see the world. While walking in the park they see a young alien girl trying to get her "cotha" out of a tree. Mark saves the cotha, and the girl eats it alive. Mark tells himself and Eve that it's an alien planet, and Eve says that it won't let them forget. Mark hopes that Thragg got sucked into a black hole, unknowing of Thragg's actual condition.Over the next few weeks, Mark spends time with Eve and Terra as they adjust to life on Talescria. Mark and Oliver go on a job for the Coalition and find an illegal Kanslok farm. They fight a creature known as a Rynax. After defeating it, they report back to Allen, who tells them that Thragg has probably killed Space Racer. Mark, Oliver, and the Coalition decide to move in on Space Racer's last known location. When they arrive however, Thragg was gone. They start searching the planet. Mark enters a cave where he finds a creature emitting a blue light. Upon touching it, a flash of light blinds him, and the next thing he realized is he was sitting on the toilet, reading Science Dog, the same way he was before he had his powers.
Mark progressed through the day with knowledge of everything that would happen. He approached Atom Eve and asked her about the Teen Team. She hadn't met him before and was shocked that he knew her secret identity. She dragged him to meet with the others. They were all in disbelief that he knew so much about them, yet they had never met him before. Over the next week, he told them how to win all of their future battles with David Hiles, the invading Flaxans, and the Mauler Twins.
Soon, Nolan noticed that Mark seemed depressed. He asked Mark what was going on. Mark took him outside and revealed that he had his powers. Nolan was elated. However, Mark told him he needed to promise that he truly loved him. Nolan said he did, of course. Then Mark asked him not to turn evil and invade Earth as he was secretly planning to. Nolan became angry and immediately attacked Mark. Mark led him to Utah where he tricked Nolan into smashing into the Guardians of the Globe headquarters. He revealed Nolan's plans to the Guardians and they subdued Nolan before he could kill them. Cecil Stedman soon arrived and brought Nolan back to the Pentagon to restrain him. However, upon waking up, Nolan pleaded that he was sorry, and that he felt regret for what he had done.
Later, Mark continued to save countless lives by knowing when the bad guys would strike and how. He saved Eve several times, but had to keep his distance as she was still dating Rex in the present timeline. One night Mark is once again approached by the mysterious entity. It offered him a chance to stay there and save lives, or return home. He decided to return home, as he couldn't bear to be away from his daughter. The entity was confused that he would trade countless lives for for one, but Mark confirmed his decision. Mark was brought back to his original timeline.
The New Status Quo
Mark learns that five years has passed since he experienced the "reboot". He flies back to Talescria, and discovers that Terra was now a small child instead of a toddler. Mark begins to weep about having lost precious time with his daughter, and asks for her forgiveness. She forgives him and they embrace. A sad Eve embraces him too. After putting Terra to bed, Mark and Eve discuss what happened during Mark's venture in time. He cries as he says that the many lives he saved are lost due to him choosing his daughter over them. Eve comforts him but looks in distress, realizing that sooner or later she will have to tell him about something. They take Terra to school, and later they go to meet Allen. Allen embraces Mark and is joyous to see him. Mark reports that he was in that state for what he believed was a short time. Allen states that he'll check it out. Mark asks about Oliver and Allen says that he is fine. Allen asks for Mark's help again to stop Thragg and Mark blatantly refuses. He goes to a party at Allen's house later and talks with Oliver. Mark watches the sky while others are mingling. Oliver asks how he is doing with Mark not recognizing him at first. Mark starts to cry and Oliver conforms him. The next day, Mark and Eve go on vacation with Mark being happy to have his family back. They arrive and Eve reveals that she was seeing someone while Mark was gone. While talking with Eve about it, he says that he understands. Later, he tries to take Terra flying, but she gets scared. Mark later reads Terra a story. After they relax throughout the day, Mark and Eve talk about what's happening on Earth since they haven't heard from Nolan in a while. They visit Allen in the hospital after his attempted assasination. Later, Mark, Eve, and Terra (and Eddy) visit Nolan and Debbie on the Moon, where Mark learns that Nolan and Rex have become friends. Anissa, having heard that Mark is back, tries to talk with him, but gets attacked by Eve and sent away by Nolan. Mark tells Eve later that he doesn't want his parents to know what she did to him.
Mark briefly goes to Earth where he and his father meet up with Rex. Rex tells Mark all the good he has accomplished in the last five years, and how everyone but Monster Girl and Monax are on his side. Rex has even managed to sway some villains, such as the Mauler Twins, by just giving them what they want, if their desires are reasonable enough. Mark talks to his father privately in outer space, where he says that he still cannot trust Rex after everything he's done. Nolan tries to convince Mark that Rex's leadership is a good thing, but to no avail. After saying goodbye to his parents on the Moon, Mark and his family leave. Mark reflects on how strange his life has been, which Eve misinterprets as him passing judgement on her affair with Kubian. Mark apologizes, even though Eve says that she should because she was the one who did something wrong. When they get back to their new home planet, Mark asks Eve if she wouldn't mind hiding out there forever.
