Origin

Justin Jin is a Korean-Canadian teen living in Vancouver, where he helps his single mother run a bakery. His grandfather was Jin Taiko, the avatar of Cyttorak before Cain Marko. When his parents divorced when Justin was 5, his father returned to Korea. Years later, his father would be killed in a random attack. His belongings, including a sliver of the Crimson Gem, were shipped to Justin as next of kin. As soon as he touched the gem, he was imbued with the power of Cyttorak and became the new Juggernaut, since Cain Marko had recently rejected the god and connected to his power in a different way.

Justin rejected Cyttorak's plans for destruction, and the angry god said he had worse plans for Justin than leaving him without powers.

Avengers Academy

When word of a Vancouver Juggernaut doing heroic deeds started getting around, Professor X and the original X-Men went to investigate. After seeing him in action, Professor X offers him a chance to join the Avengers Academy to be trained by Carol Danvers, which he accepts. Early into their first semester together, they were attacked by Swarm. It took the combined powers of the entire class to defeat Swarm, revealing his employer, Hexus, might have an interest in the new school.

After some time together, they were forced into action, despite Danvers' instructions not to, when Stanley Osborn, brother of fellow student, Red Goblin, was kidnapped by a new Sinister Six. Among the Sinister Six was Mysteriant, a lover of classmate Aaron Fischer. Despite Aaron's flirtations with classmate Justin, Aaron sought out Mysteriant, who agreed to help the team get Stanley back.

Mysteriant would make good on being their inside man. He even went as far as to use his illusions to trick his leader, Squid Kid, into thinking he stumbled upon his betrayal. When the Sinister Six ambushed the cadets, it was a trap to keep the villains distracted while the students free both Stanley and the sensitive business data of the likes or Roxxon and Hexus that Squid Kid had been holding for ransom. Although, rather than return it, Mysteriant had it dumped on the internet for the public to see.

Serpent in the Garden

Bloodline witnessed her classmate, Escapade, being kidnapped by Emplate, a vampiric mutant who can move through dimensions just like the new academy campus can. She rounded up any of the class or faculty that happened to be around, including the new residential advisor, Hazmat. Danvers told everyone to stay put while she works with mutant and sorcerers to get to the bottom of it, and Justin followed orders. Unfortunately, Emplate was stealing Escapade's ability to help him move through the dimensions. Once he had her ability, he snuck into Justin's room, dragged Justin to his dimension, and locked him up with Mettle, an Avengers cadet that was presumed dead.

A rescue team made of Hazmat and Bri arrived to save Justin and Shela. When Mettle saw his girlfriend, Hazmat, he found something to live for and then the strength to punch through Emplate's prison walls and return to the campus. Unfortunately, they found the cadets left behind transformed into familiars of Emplate. Justin was cornered by Aaron, under Emplate's influence. Before either of them had to fight each other, Shela reached her full potential, stacking her switches for the first time. She managed to dilute Emplate's infection across her friends, curing them, while taking enough of each of their powers to overwhelm and banish Emplate from this dimension.

Arnie Roth Community Center

When Aaron wasn't attending class, he was working at the Arnie Roth Community Center for the LGBTQ+ community, named for Captain America's childhood friend. One day, Justin was bringing Aaron lunch when, under the guise of a traditional values social media influencer, Sin, daughter of the Red Skull, convinced a number of homophobes to protest the community center. Hydra agents embedded in the crowd faked a mutagenic attack that turned a protester into a monster. Justin manifested his armor and took the monster down in front of Daily Bugle reporter.

There was more violence inside the community center, and Justin charged in to help Aaron. Aaron asked him to start evacuating people. Aaron would fight Sin, but she was better trained them him. He was able to knock a detonator out of her hand and delay a larger attack. Thankfully, Qaari snuck away and put his tech expertise to good use disarming the bomb. When the duo were joined by Kid Juggernaut on the roof, Sin made her escape by helicopter.

As the dust settles, Justin starts dating a reporter who was covering the attack, Marcus Wetherell.

Lost in Time

As revenge for failing to enchant Kid Juggernaut, Enchantress curses the Avengers cadet to speak their hearts’ truths, leading to some awkward conversations. Jara, the lost valkyrie who runs the ice cream shop across the street from campus and has grown to like the students, uses a magic trinket of her own to undo the curse. However, these magical spells weaken the M’Kraan crystal that holds the campus in a superposition across time and space. Kid Immortus needed to send the cadets into time to correct incursions. Aaron and Justin found themselves in WWII working for a platoon led by Arnie Roth.

Among the platoon was Jin Taiko, Justin's grandfather They were taken captive by the Japanese Hydra Supreme and forced to mine for the Crimson Gem of Cyttorak so that Hydra could finish the Satan Claw. With Aaron and Justin's help, they managed to smuggle dynamite so they could blow a dam, but Taiko was injured. The platoon brought him to a temple to Cyttorak where he became the Juggernaut to save his life. This corrected Taiko's timeline allowing Kid Immortus (campus chaplain) to reach Aaron and Justin and rescue them.

One World Under Doom

When Doctor Doom usurped the title of Sorcerer Supreme, he used it to install himself as world emperor. A Hydra splinter group, led by Sin (still using her Cherry Crane alias) used the confusion to hide their new illegal activities as they rounded up seditious residents of America including Jara and Marcus. The cadets locate Marcus on a maglev train Hydra was using to travel the country. As resident heist-master, Shela made a plan for them to board the train.

Blackheart opened portals to campus that the cadets could lead prisoners through, but his magic finally got the attention of Doom. He disliked the interdimensional magic of his mother’s torturer on Earth. He sent a fleet of doombots to take out Blackheart, who needed to be defended by the cadets. Meanwhile, Shela and Justin went to rescue Marcus from Sin and her enforcer, Maphegor, an apostle of Cyttorak. Shela tricked Sin into pushing her off the train so Shela could switch places with her midair, and Malphegor made his escape after Justin broke his crimson staff.

After Justin stopped the train, the cadets were finally confronted by Doom himself. They were completely overwhelmed, but Shela had an idea. She tried to attack Doom, who grabbed her and readied to attack. Shela then switched back with Sin, who took the brunt of Doom’s energy blast. Just as disgusted with Hydra, Doom burned the skin off Sin’s face yet again. Satisfied with whatever success he accomplished, Doom decided to leave Blackheart to his new prison of humanity.
