Invincible is an American comic book series written by Robert Kirkman and, illustrated by Cory Walker and Ryan Ottley, and published by Image Comics. Set in the Image Universe,^[1] Invincible follows the coming of age of superhero Mark Grayson / Invincible, a half-Viltrumite and first-born son of Omni-Man, the most powerful superhero on Earth. The series began publication on January 22, 2003, before coming to a close on February 14, 2018, with 144 issues. Several spin-off series were released over its run: Brit, The Pact, Atom Eve & Rex Splode, and Guarding the Globe. An animated television adaptation began streaming on Amazon Prime Video on March 25, 2021,^[2] while an additional spin-off interquel, Battle Beast, began publication in 2025.

Mark Grayson is the son of Nolan and Debbie Grayson. Nolan, an alien from the planet Viltrum, is Earth's most powerful superhero, "Omni-Man". When Mark is seventeen, his powers manifest, and he quickly uses them to fight crime, taking the moniker "Invincible." He becomes acquainted with the Teen Team, made up of Robot, Rex Splode, Dupli-Kate, and Atom Eve, with whom he becomes close. He also meets Allen the Alien, an agent of the intergalactic Coalition of Planets, which safeguards planets from threats.

Nolan suddenly kills Earth's premier superhero team, the Guardians of the Globe. The world is unaware of his actions until the villainous Mauler Twins revive the team's leader, the Immortal. He attacks Nolan, who kills him again, but is witnessed by Mark and the rest of the world on live television. Nolan reveals to Mark that his race, the Viltrumites, are actually planet-conquering warriors whose ultimate goal is the expansion of their empire. Nolan was sent to Earth to conquer it and tries to convince Mark to join him. He refuses, and they fight, with the battle resulting in the deaths of thousands of innocent civilians and Mark being beaten nearly to death. Changed by the people of Earth and Mark's love, the regretful Nolan leaves Earth, unable to kill his son.

When Mark recovers, he meets Global Defense Agency director Cecil Stedman. Now working for the GDA, he meets other heroes and encounters villains who become recurring enemies, such as the Sequids and Flaxans. In a raid to defeat the crime boss Machine Head, Mark helps his enforcer, Titan. Joined by the Teen Team, they defeat his forces but are easily defeated by the alien warrior Battle Beast, who promptly leaves. Under Cecil's orders, Robot forms a new Guardians of the Globe team made up of the Teen Team, new heroes like Monster Girl, and the revived Immortal. Allen tells Mark that the Coalition of Planets is looking for allies to defeat the Viltrum Empire.

Meanwhile, Angstrom Levy, a scientist who can form multiversal portals, attempts to merge the intellect of his alternate selves to gain vast knowledge, enlisting the Mauler Twins' help in constructing a machine to accomplish his goal. Mark's intervention leads to the accidental deaths of Levy's counterparts and his disfigurement. Due to his alternate counterparts' shared hatred of Invincible, who in many other dimensions turned on humanity and joined his father, Angstrom vows revenge on Mark.

In space, Allen is beaten nearly to death by three Viltrumites, but he grows stronger upon healing due to a Unopan breeding program designed to create a specimen strong enough to defeat a Viltrumite. Coalition leader Thaedus reveals to Allen that he himself is a Viltrumite, the first to rebel against them, and tasks him with retrieving Mark and Nolan to help their cause. Mark is contacted by an alien from the planet Thraxa for his assistance, unexpectedly reuniting with Nolan, who reveals he had a child with a Thraxan, Andressa, and needs his help to save Thraxa from Viltrumites sent to eliminate Nolan for abandoning Earth. Viltrumites attack the planet and kill millions of Thraxans. Mark and Nolan battle them, with Nolan killing one, before he is defeated by another, Lucan. More Viltrumites arrive and take Nolan captive, while Viltrumite General Kregg appoints Mark as Earth's subjugator. Before he is apprehended, Nolan begs Mark to read his books. Mark spends time on Thraxa to help rebuild. Andressa asks Mark to take the child with him back to Earth to give him a better life. Mark returns home with the child, whom Debbie names Oliver.

Robot creates a human body using the DNA of Rex Splode and reveals it to the Guardians. The Sequids attack once again, but Mark and the Guardians are able to repel the threat. Angstrom returns and attacks Mark, Debbie, and Oliver. Angstrom sends Mark through multiple universes in an attempt to weaken him and severely injures Debbie. Enraged, Mark tackles Angstrom out of the house, and their fight takes them across multiple universes. The fight ends with Mark seemingly beating Angstrom to death, but he is horrified by his actions. Stranded in an alternate dimension, he is rescued by a future version of the Guardians. Before sending him back to his timeline, the future Eve confesses that she loves him.

Oliver grows at an accelerated rate, becoming a preteen in a few weeks, and starts showing signs of Viltrumite powers. Allen comes to Earth to recruit Mark and Nolan, but Mark reveals Nolan’s current incarceration. Mark gifts Allen Nolan’s books, which he believes secretly hint at weapons that can be used to kill Viltrumites. Equipped with new information, Allen thanks Mark and leaves to find Nolan. A Viltrumite named Anissa comes to Earth to check on Mark's progress. When she realizes he has made no progress, Anissa quickly subdues him with no casualties and few injuries to Mark. Anissa warns Mark that a more ruthless and violent Viltrumite will check in on Mark, and if he continues to defy the Viltrum Empire, Earth will pay. Anissa leaves and runs into Allen, who allows himself to be captured to find Nolan aboard a Viltrumite prison ship. Following the battle, Cecil has Mark train rigorously to hopefully stand his own against the Empire.

Some time after, the geokinetic villain Doc Seismic kidnaps all of Earth's heroes save for Mark and Eve. The two attempt to rescue the heroes, but Seismic's creatures overwhelm them. Cecil sends in D.A. Sinclair’s “Reanimen,” undead robotic soldiers constructed by the mad scientist whom Mark previously imprisoned; Cecil also sends in Darkwing II, another supervillain Mark had defeated. The Reanimen and Darkwing II overpower Doc Seismic. Mark erupts in anger that Cecil is working with villains and confronts him. Cecil explains that criminals can be rehabilitated and repurposed to benefit the planet. Their argument results in Cecil deploying the Reanimen to calm down Mark. The ensuing fight carries over to Guardian headquarters. After removing a transmitter emitting high-frequency vibrations - a Viltrumite weakness - Mark cuts ties with Cecil. The Guardians split, either taking Mark's or Cecil’s side. Mark confesses his feelings to Eve, and they begin dating. Mark begins to fight crime independently and trains Oliver. During a mission to fight the Mauler Twins, Oliver kills the two, believing that killing their enemies would make things easier in the long run, much to Mark's dismay.

Nolan is sentenced to death for his actions on Thraxa, but Viltrumite law dictates that he must be at full strength before execution. Allen convinces Nolan to join the Coalition, and the two escape from prison with the help of Battle Beast, who was also imprisoned on the ship. The three kill the two Viltrumite guards, along with most of their security forces. Battle Beast disappears in the chaos, and Nolan reveals to Allen that there are fewer than fifty pureblooded Viltrumites left in the universe. Mark continues to fight crime and his morality is continually questioned: he is forced to kill a future version of the Immortal who was left in charge of the planet after Mark left; helps Titan keep his position as a crime boss due to his influence significantly bettering the city; and fights the vengeful supervillain Powerplex, whose family was killed during Mark and Nolan's fight. Mark and Oliver realize that they are being watched by mysterious technological floating orbs, but Robot is unable to figure out who sent them, and Cecil denies GDA involvement.

The orbs are revealed to be under the control of Angstrom Levy, who survived his fight with Mark with the help of a race of technological beings called the Technicians. Angstrom launches an ambush on Mark’s Earth with 20 evil, alternate versions of Invincible. The alternate Marks lay waste to Earth, resulting in mass destruction and death, including Rex Splode. Atom Eve is injured in battle. When the remaining eight Marks turn on Angstrom, he traps them in the wasteland universe. Mark fights Angstrom, with Oliver convincing Mark that Angstrom is too dangerous to remain alive. Mark prepares to kill Angstrom, but he manages to escape before Mark can kill him. The GDA capture the bodies of the deceased Marks and convert them into Reanimen. As Mark is helping in the cleanup, the Viltrumite Conquest arrives on Earth to inspect Mark's takeover. Conquest defies his mission parameters and attacks Mark. Conquest severely injures Oliver and nearly kills Eve when they attempt to aid Mark. Before she dies, Eve's mental blocks are overridden in her near-death state, and she severely burns Conquest. After a gruesome last stand, Mark eventually beats the Viltrumite. As Mark recovers, Cecil secretly keeps Conquest's body, intending to interrogate him about the Viltrum Empire and how to stop them. Mark, Eve, and other heroes attend Rex Splode's funeral, where Robot takes Rex's name, and Monster Girl declares her love for him. Immortal retires and proposes to Dupli-Kate, who accepts. The Technicians claim Angstrom as a slave to find them a new home. Battle Beast recovers from the prison battle. The Sequids prepare for a final assault on Earth. Mark visits Oliver in the hospital, promising to no longer hesitate about killing anyone who threatens his family.

Nolan tells Allen about how, centuries ago, enemies of the Viltrum Empire created a disease known as the Scourge Virus that killed over 99% of the Viltrum population. But with Mark's potential apparent, Earth is to become a breeding camp for the Viltrum Empire to replenish their ranks. Allen takes Nolan to the Coalition homeworld, Talescria, and introduces him to Thaedus. Thaedus tasks the two of them with finding the weapons and people that Nolan wrote about in his books to aid in their fight against the empire. Nolan and Allen do so, bringing the space-traveling, gun-wielding alien Space Racer to the Coalition, along with other weapons and creatures that can hurt Viltrumites. Thaedus shows Nolan a new strain of the Scourge Virus, which has the potential to wipe out every Viltrumite in the universe if the empire proves to be too much for them. Mark continues fighting crime for a while, encountering the ecoterrorist villain Dinosaurus, who transforms from his human form into his dinosaur form whenever he feels indifferent about something. Mark nearly kills him before the Guardians intervene. The Sequids attack and nearly overwhelm the Guardians before Mark kills their leader, the possessed Rus Livingston, and Robot kills the last Sequid. Conquest escapes from Cecil's detention center and returns to the empire, where Grand Regent Thragg orders him to kill Mark, Nolan, and Oliver. Eve also finds out that she is pregnant, but she keeps it a secret from Mark.

The Flaxans attack Earth again, and Robot and Monster Girl follow them back to their home dimension. Nolan and Allen return to Earth, where they recruit Mark, Oliver, and the hero Tech Jacket for the war against the Viltrum Empire, the Viltrumite War. On their way back to rendezvous with the Coalition, the group is attacked by Conquest, Lucan, and Randee. Mark manages to strangle Conquest to death, but is gravely injured. Nolan and Oliver look over Mark in secret on an alien planet for the next 10 months and take the time to train and bond with each other. Allen and Tech Jacket are able to return to Talescria in secret and spend months helping the Coalition fight the Viltrumites. Mark recovers, and he, Nolan, and Oliver get to Talescria to assist the Coalition in defending the planet from a Viltrumite attack. The Viltrumites flee, and Mark, Nolan, Oliver, Thaedus, Allen, Tech Jacket, Space Racer, and Battle Beast follow them back to their home planet of Viltrum, now a memorial to those who died to the Scourge Virus. In the resulting battle, some Viltrumites are killed, and Mark, Nolan, Thaedus, and Space Racer destroy Viltrum. Enraged, Thragg decapitates Thaedus and gravely injures Mark, Nolan, and Oliver. Before he lands the final blow, Thragg spares them. After recovering from the battle, the Coalition believes that the Viltrumites have gone to Earth to lay waste to it. Mark, Nolan, and Tech Jacket race back to Earth, expecting it to be destroyed, but find it intact. Thragg intercepts the group and gives them an ultimatum: allow the remaining 37 Viltrumites to breed with Earth's population and replenish their ranks, or fight them all and have every living being on Earth likely killed in the resulting battle. Fearing for Earth's safety, Mark agrees, and the Viltrumite War ends in a truce. Mark and Nolan return to Debbie, Cecil, and Eve and inform them of the end of the war. Nolan and Debbie reconcile and restart their romance. Allen is made leader of the Coalition in the wake of Thaedus' death and comes across the Scourge Virus that Thaedus showed Nolan, along with instructions left by him: if Thaedus dies, use the Scourge Virus to eliminate all Viltrumites from the universe.

Mark learns that Eve had an abortion while he was gone, but does not hold it against her. Mark fights Dinosaurus again in Las Vegas, which results in Dinosaurus activating bombs that destroy the city, killing thousands and presumably killing him as well. Mark fights Powerplex again and makes peace with him. Nolan and Debbie move to the GDA's moon base and decide to travel to Talescria to visit Oliver. Robot and Monster Girl return from the Flaxan Dimension. Dinosaurus is revealed to be alive and is captured by the GDA. Cecil and Mark travel to the ruins of Las Vegas, where Cecil reveals that they are using the glass created by the bombs to take advantage of solar energy to provide power to millions of people. Mark realizes that Dinosaurus's methods, while abhorrent, also have positive results. When Mark breaks Dinosaurus out of the Pentagon, the two team up to do good for the planet, but Cecil declares them enemies of the planet. Meanwhile, on Talescria, Allen reveals to Nolan that the new strand of the Scourge Virus has the potential to kill the Viltrumites hiding on Earth, but also the potential to kill every human on Earth. Nolan disagrees with Allen, as he believes that Earth can change the views of the Viltrumites as it did for him. The two fight, and Oliver intervenes before deciding to assist Allen with his plan. Nolan is imprisoned on Talescria while Allen and Oliver travel to Earth. Mark meets the two of them in space, where the duo reveal their plan. Mark refuses to risk the lives of the humans, and a fight breaks out. Mark is nearly overpowered by the two of them before Thragg arrives to assist him. Thragg and Allen talk and try to resolve the issue peacefully, but the Guardians arrive and see Mark, who is still an enemy of the planet. Another fight breaks out, and Oliver attempts to unleash the Scourge Virus, but Mark is infected.

Mark is put in critical condition, and Thragg has Viltrumite scientists on a Viltrumite warship heal Mark to prevent the Coalition from attacking them. Dinosaurus goes to the warship to assist in Mark's recovery. It is then that Thragg realizes that Mark is the grandson of Argall, the former Emperor of Viltrum, making Mark, Oliver, and Nolan the heirs of the Viltrum Empire. Thragg attempts to kill Mark, but Dinosaurus intervenes, and the two escape. Mark is now healthy enough to walk, but his powers are gone. The Flaxans attack Earth, and what happened in their dimension is revealed: Robot and Monster Girl overthrew the Flaxan dictatorship and became the rulers of the dimension, but rebellion after rebellion caused Robot to become especially cold and pragmatic, straining his relationship with Monster Girl. It is also revealed that the pair spent 1,000 years in the Flaxan dimension, where they aged very slowly. The Flaxan attack is stopped, but not before there are thousands of casualties. During the attack, General Kregg, to Thragg's chagrin, saves a group of people that included a romantic partner of his. All of the Viltrumites except for Thragg and Anissa had taken on a romantic partner and began to see the appeal of humanity and proper companionship.

Mark's powers return, and he reconciles with Allen and Oliver. Mark continues to work with Dinosaurus to do good for the Earth. Dinosaurus reveals that he had placed bombs in Greenland to cause flooding to kill several humans and provide water to barren areas. Mark fights Dinosaurus and alerts the Guardians to the bombs, but they fail to deactivate the bombs. The bombs detonate, destroying Greenland and causing floods that kill over a million people. Robot constructs a moon-sized base to cause an artificial tide to put the water back to normal. Mark talks to Dinosaurus and says that Dinosaurus might have a god-complex and that there must be better ways to help Earth. Dinosaurus agrees and asks Mark to kill him, believing that he may go back into his old line of thinking and could cause even more destruction. Mark kills Dinosaurus, and Cecil offers Mark a job at the GDA so that he will not get arrested for helping Dinosaurus. Eve reveals to Mark that she is pregnant and wants to make it work.

Thragg attacks Nolan and reveals to him his heritage. Before he can kill Nolan, Kregg, Anissa, Lucan, and the Viltrumite Thula intervene, declaring their loyalty to the rightful heir of Vilrum. The four nearly kill Thragg, but Nolan orders them to spare him. Nolan is declared the Emperor of the Viltrumites and exiles Thragg, believing that to be a more fitting punishment for him. Angstrom returns, attacks Eve, and sends Mark to the wasteland universe. There, he discovers that the alternate Marks resorted to cannibalism to survive. Mark and his mohawk-wearing counterpart, "Mohawk Mark," team up to survive the insane "Sinister Mark." Meanwhile, Eve talks to Angstrom and convinces him to stop his war on Mark, telling him that he could have done good if he hadn't focused on trying to kill Mark. Mohawk Mark kills Sinister Mark in the fight, before he and main Mark go back to the main universe. Angstrom surrenders, but Mohawk Mark kidnaps him and brings him back to his universe to expand his empire. Mark asks Robot to track him down, believing that Angstrom is still too dangerous to live. Nolan tells Allen about Thragg's exile, and Allen tasks Battle Beast with tracking him down and killing him. Robot creates a device to track down Angstrom, and he and Mark go to Mohawk Mark's universe to kill him against Eve's wishes. Mohawk Mark shows the duo the captured Angstrom. Robot double-crosses Mark and decapitates Angstrom and liquefies Mohawk Mark's insides and leaves main Mark stranded in Mohawk Mark's universe.

Mark enlists the help of that universe's Robot to return home. The process takes six months but is ultimately successful, and Mark returns home. There, Eve reveals that Robot told everybody that he was dead. She breaks up with Mark, refusing to raise their child in an environment where they are not sure if he will survive his adventures. The heartbroken Mark leaves the house before being raped by Anissa when he refuses to have sex with her. Mark returns to Cecil to find out where Robot is. Robot arrives and kills Cecil, and has Mark follow him to his house. Robot attacks Eve and severely injures her, forcing Mark to flee with Eve to a Viltrumite warship. While the duo are on the ship, Robot unleashes several drones that kill dozens of heroes and villains. Robot reveals the slaughter to Monster Girl, saying that he can't allow them to get in his way. She tries to attack Robot, but he sends her out into space, where Anissa rescues her. Eve gives birth to their daughter, whom they name Terra. Eve and Mark reconcile, and Mark goes to stop Robot. Robot sends out an envoy to the Viltrumites and explains his long-term plans to turn Earth into a utopia. Nolan, realizing that the plans do have merit and too many Viltrumites would die in the attempt to fight Robot and his drones, agrees to keep the Viltrumites neutral in the conflict. Mark attacks Robot's stronghold, but Robot explains how Mark is both physically and morally outmatched. Mark leaves Robot to continue his utopian plans.

Battle Beast tracks Thragg to Thraxa, where he has begun the process of mating with every female Thraxan to create an army of Thraxan-Viltrumite hybrids, with him noting Oliver as inspiration. The two battle across the planet for days. Mark sees the good that Robot's utopia has done, but several surviving heroes like Immortal, Dupli-Kate, and Monster Girl desire revenge against Robot for the murders he committed. Believing that he would eventually intervene and cause more damage, Mark, Eve, and Terra decide to leave the planet. Allen sets them up on Talescria, where the three take time to grow accustomed to living and being parents, with Oliver, now resembling a young adult, helping out. Thragg eventually kills Battle Beast by ripping out his heart, but is severely injured. Allen hears of the weakened Thragg and enlists Mark and Oliver as Coalition agents to kill him. The duo arrive too late and search multiple planets to find Thragg. Mark comes across an alien cave that sends him back in time to when he first got his powers. Mark makes some changes to the past that save millions of lives, but realizes that if he spends too much time in the past, his relationship with Eve and Terra being born would be undone. The alien in charge of the cave is disappointed, but sends Mark back to his time. Mark returns to Eve and Terra and discovers that five years have passed.

Mark makes up for the lost time with Eve and Terra. Mark also reveals to Nolan and Eve that Anissa raped him, but asks them to spare her, as he sees that the Viltrumites are a changed people. In the five years that Mark was gone, Thragg and his army of Thraxan-Viltrumite hybrids have taken over dozens of planets, with the twins Onaan and Ursaal being Thragg's second-in-command. Allen tasks Oliver with infiltrating Thragg's army. Oliver works to undermine Thragg's army, but Thragg tasks him with standing idle while he and the twins kill Mark, Eve, and Terra. Thragg and the twins track down and attack Mark, Eve, and Terra, but Oliver intervenes. In the resulting fight, Terra awakens her powers, and Thragg fatally impales Oliver. Mark and Eve manage to overpower the twins, and Mark decapitates Onaan, telling Thragg, "Being a hero is bullshit," before engaging in a short skirmish with him. Thragg rips Mark in half, and Ursaal beats Eve nearly to death, but Thragg orders her to stop, telling her that they will mourn Onaan and leave Terra to watch her parents die. Eve's near-death powers activate, and she and Mark are healed, with Mark getting stronger, but she is unable to save Oliver. Mark and Eve agree that they must join the war effort against Thragg and his army.

The Coalition holds a funeral for Oliver. There, Mark and Allen argue over Oliver's involvement, but while Allen apologizes for taking a risk with Oliver, Mark also realizes that Allen thinks like a leader, which may be the right thing to do. Mark is able to convince Nolan to recruit the Viltrumites for the war, and also reveals to Nolan Anissa's assault. Ursaal also begins to doubt how much Thragg cares for her and his children. Mark, Eve, the Viltrumites loyal to Nolan, and the Coalition are able to push the Thraxan-Viltrumite army out of their territories and take them to a final battle near the Sun. Several of Thragg's children and Nolan's Viltrumites die in the battle, including Anissa, who gives Eve a final message before she dies. Nolan takes on Thragg, but is overpowered and mortally wounded. Mark engages Thragg, and their fight makes it clear that Thragg does not care about his children — he only cares about revenge against Mark and Nolan. Ursaal orders her siblings to stand down, and they do, allowing the Coalition to take them into custody. Mark and Thragg fight on the surface of the Sun, and Robot, who heard of the battle and, realizing that Thragg is a threat to humanity and the universe at large, assists Mark by sending him an armored suit to help in the fight. After a violent fight, Mark bites Thragg's throat out and sends his body into the Sun to be destroyed.

As Mark recovers, Nolan asks to see him. Realizing that he can't heal properly and is on death's door, Nolan declares Mark to be the new Emperor of the Viltrumites. Nolan says that because Mark changed him, he can lead the empire into a new era and asks him to "change them" as he dies. Mark, Eve, Terra, Debbie, and Allen mourn Nolan. Mark's first act as emperor is to end Robot's rule over the planet. Mark spares him and reduces him to a brain and asks Immortal to become the new director of the GDA, as he can be trusted to use peaceful methods to better the world, but Robot can still act as an advisor to him. Shockingly, Robot agrees. Eve passes on the message that Anissa told her — Mark has a son named Markus, born out of the rape of Mark. Markus soon develops his powers, and Mark comes to the decision that the Viltrumites need to leave Earth before their influence becomes too great. All of the Viltrumites, including their families and the survivors of the Thraxan-Viltrumite army, leave Earth, except for Markus, his stepfather, and half-sister.

500 years later, the universe is a changed place. Mark and Eve have led the new Viltrum Empire into an era of peace and regularly help other planets with their problems. Markus has come to terms with his conception, and his and Mark's relationship has improved, and the Coalition has disbanded. The comic ends with Mark and Eve reflecting on the universe as Mark finds amusement in the fact that it started when his father asked, "What will you have after 500 years?"

Robert Kirkman is the sole writer of the series. Cory Walker co-created the book, designed several characters, and provided art from #1 to #7. Ryan Ottley assumed art duties with issue #8 and drew most future issues, with Walker returning for a select few. Kirkman has provided back-up space for a few aspiring comic creators, most notably Benito Cereno and Nate Bellegarde. The series is known for its extreme graphic violence despite its colorful nature and visuals.^[3]

The series ended on February 8, 2018 with issue #144, with Walker returning as artist.^[4] The double-sized final issue was released on February 14, 2018.^[5] In April 2022, it was announced that a Battle Beast story would be published in Skybound X #25, with Kirkman and Ottley reuniting for the story; it was published on July 20, 2022.^[6] In October 2022, it was announced that, in celebration of the series's 20th anniversary in 2023, its first issue would be getting a reprinted facsimile edition reprint and a deluxe edition reprint, compendiums 1-3 would be getting comic shop exclusive hardcover versions, and there would be a reprint of the series in a new 6"x9" graphic novel format with new covers from Cory Walker and Dave McCaig, an Invincible Universe compendium, and a secret announcement in January 2023 (which was later revealed to be a teaser for season two of the animated show).^[7]

In December 2024, it was announced that Kirkman and Ottley were developing a prequel series entitled Invincible Universe: Battle Beast. The series, set between issues 19 and 55 of the original Invincible series, follows Battle Beast as he embarks on a quest to find an opponent strong enough to kill him. The first issue of the series is set to debut April 2025.^[8]

In 2003 and 2004, Image and Robert Kirkman published several other superhero series: Tech Jacket pencilled in a manga style by E. J. Su (cancelled at #6), the 3-issue Capes Inc. series drawn by Mark Englert and three oneshots starring Brit, the first two with artwork from Tony Moore and the third with artwork by Cliff Rathburn.

In 2007, Brit was launched as an ongoing full-color series written by Bruce Brown, with artwork by Cliff Rathburn. The series was overseen and edited by Robert Kirkman. In late 2007, a two issue mini-series starring Atom Eve was released.

Tech Jacket was first collected as a digest-sized, black and white graphic novel and later reissued in regular sized, full color and a cover scheme similar to Kirkman's other trade paper backs. Capes was collected as a trade paperback in summer 2007, and the three Brit one-shots were colored by Val Staples and published as a collection in 2007, as well.

At first shown to barely coexist in the same universe, the characters have since been integrated into Invincible's book. Tech Jacket was an ongoing series that tied into Invincible #27, and the character has been seen in the background of various battles during the series. The characters from Capes have also been supporting characters seen mainly in large superhero battles Invincible participates in, and the series ran as a back-up in the Invincible book starting with #27. Brit has had an even less substantial role, appearing a couple of times in the aforementioned brawls (understandable considering that after the last book Brit was somewhat-retired). Brit later went on to become the leader of the Guardians of the Globe and was featured heavily in comic spin-offs Guarding the Globe and Invincible Universe. In The Astounding Wolf-Man, Art, Invincible's tailor, appeared, designing the title character's costume. Wolf-man has also appeared in Invincible #48 & 49.

• Mark Grayson / Invincible: A titular superhero and main protagonist of the series. Mark is a 17-year-old high school student and a Viltrumite/human hybrid, who is the son of most powerful superhero, Omni-Man/Nolan Grayson, a male Vitrumite from the planet called Viltrum, and human mother, Debbie Grayson. Mark inherited his powers from his father such as superhuman strength, speed, agility, reflexes, nigh-invulnerability, longevity, and flight, and soon became the superhero, "Invincible" as he strived to use his powers to fight evil.
• Nolan Grayson / Omni-Man: Mark's father, Debbie's husband, and formerly the most powerful and greatest superhero of Earth known as "Omni-Man". He was originally sent by the Viltrumites to prepare the Earth to be conquered by them, but has a change of heart and begins showing compassion for others after nearly killing Mark after his secret is revealed. He works together with Mark, Allen, and his second son Oliver to combat the upcoming threat of the Viltrumites before he is crowned their new emperor when it's revealed he was the son of Emperor Argall.
• Debbie Grayson: Mark's mother, Nolan's wife, and stepmother of Oliver Grayson.
• Oliver Grayson II: Mark's alien half-brother. The result of a relationship between Nolan and a member of the Thraxans named Andressa, who have short life spans, growing at a rapidly increased rate compared to humans, though his father's DNA is slowing his aging over time. Although his mother is an insectoid, he resembles a Viltrumite/human with purple skin (later fades to pink). Andressa tells Mark to take Oliver to Earth, so that he can have a life with the people there, because their lifespan is longer than her people's and he gets adopted by Debbie. He first takes the sobriquet of Kid Omni-Man and then Young Omni-Man as he attempts to rehabilitate the memory of Omni-Man in the general public. Oliver was later killed by Thragg while protecting Terra Grayson.
• Samantha Eve Wilkins / Atom Eve: A former classmate of Mark's and member of the Teen Team. Eve was created as a result of a government experiment to create a human super-weapon for the military. She was born with an extensive knowledge of biological and chemical sciences, and can manipulate all matter on a molecular level, although a neural mental block was implanted while she was a fetus that stops her from manipulating living animals and other beings. In the event of a severe enough or near-fatal trauma, Eve is able to break her mental block and her powers are bolstered to nigh-omnipotent levels for a few seconds. Her biological mother, Polly, died giving birth to the latter, and her scientist creator, Elias Brandyworth, was killed by the government agent Steven Erickson. Eve currently lives with her foster parents, including her abusive foster father Adam Wilkins, and her foster mother Elizabeth. Eventually, Eve and Mark realize their true feelings for each other and the pair start dating, fall in love, and get married after Eve gives birth to their daughter Terra.
• Terra Grayson: The daughter of Mark Grayson and Atom Eve who would go on to become the second Invincible.
• Markus Murphy: Terra's half-brother. Also known as Marky, he is the son of Mark and Anissa after the latter raped the former. He would go on to become Kid Invincible.
• Lord Argall: The former emperor of the Viltrumites and the father of Omni-Man and grandfather of Invincible and Oliver Grayson. He was revealed to have been killed by Thaedus which plunged Viltrum into a civil war.

• Allen the Alien: Previously a Champion Evaluation Officer who worked for the Coalition of Planets, he tested the skills of various powered heroes on each planet in order to determine if there was a suitable "champion" who could defeat a Viltrumite. He was born in a breeding program after his race was almost eradicated by the Viltrumites. He was bred to hopefully be able to defeat a Viltrumite and was the only successful child born of the program.

  • The Immortal: Unkillable leader of the Guardians of the Globe and currently married to Dupli-Kate. He can resurrect himself as long as most of his body parts are near each other. He was a Celtic warrior who got exposed to a radioactive meteor that gave him his powers. Throughout the ages, he was a knight, a conquistador, an American Revolutionary, and Abraham Lincoln. In the present storyline, he is alive and was briefly beheaded by Omni-Man during his massacre of the Guardians of the Globe. The Mauler Twins dug up his body and reattached his head causing Immortal to live again. Revealed to rule the world as a mad tyrant in the far future, he is killed by a time-travelling Invincible at Immortal's behest, and his body parts are separated and buried far away from each other blocking his ability to resurrect. Invincible attempts to prevent the future Immortal from going mad by giving Immortal the assistance of Robot's brain to rule with suggestive guidance after Invincible leaves him in charge of Earth following Robot's downfall. However, Robert Kirkman has confirmed (in the PENvinciPALS section of Issue #144) that by providing Immortal with this assistance, Invincible inadvertently causes the very outcome he was trying to prevent via a causal loop.

He continues using his drones to work remotely (though he creates several he can be physically present within), and trains his mind to be able to split his concentration across several simultaneous activities or conversations without faltering.

  • Monster Girl: Amanda is a girl who was cursed by a gypsy, able to shapeshift into a large ogre-like creature with superhuman strength and invulnerability. Each change into monster form causes her normal self to become physically younger, until her boyfriend, Robot, figures out a solution that halts those side-effects of the curse and allows her to develop normally. She follows Robot through a portal to fight the Flaxans, where they both become trapped for nearly a millennium of subjective time in the Flaxan dimension before returning to their home dimension only a year after departure (Amanda with a body that has aged by 12 years).

• Battle Beast: Thokk is a white lion-like alien. After liberating his home world from alien oppressors he became obsessed with fighting and felt an insatiable need to engage in combat. His only goal in life being to find a champion who could best him battle. First thought of as a villain in Invicible's initial encounter with him, Battle Beast turned out to be mostly neutral, not caring for good or bad, and lived only for combat and so would go wherever he could find it. He was imprisoned on the same Viltrumite Prison Warship where Allen the Alien and Nolan were held. Allen used Battle Beast's lust for battle to convince him into helping with their jailbreak and later joining up with the Coalition of Planets against Thragg by promising lots of combat and fighting against the Viltrumites, the strongest beings in the universe. Battle Beast and Thragg eventually met in hand-to-hand combat where they battled non-stop causing massive damage across the planet upon which they fought. After several days, Thragg was barely able to beat Battle Beast with Battle Beast's final words being "Thank you."
