Avengers: The Children's Crusade was a nine-issue limited series, plus a one-shot titled Avengers: The Children's Crusade - Young Avengers #1, published by Marvel Comics between 2010 and 2012. The series represented the long-awaited reunion of the creative team behind the original, critically acclaimed Young Avengers series: writer Allan Heinberg and artist Jim Cheung. The series was conceived as a direct sequel to their initial run and as the definitive resolution to one of the biggest unresolved plot threads in the Marvel Universe at the time: the whereabouts and mental state of the Scarlet Witch. Wanda Maximoff had been largely absent from comics since she uttered the phrase “No More Mutants” at the end of House of M in 2005, an act that decimated the mutant population from millions to a few hundred. Heinberg and Cheung's story aimed to bring her back to the forefront, answer the lingering questions about her sanity and motivations, and explore the fallout through the eyes of the young heroes she inadvertently “created,” particularly her reincarnated sons, Wiccan (Billy Kaplan) and Speed (Tommy Shepherd). The publication schedule was notoriously slow, with significant gaps between issues, stretching the story's release over nearly two years. This was largely attributed to the immense detail in Jim Cheung's artwork and Heinberg's commitments to other projects, including television writing. Despite the delays, the series was highly anticipated and received praise for its emotional depth, character-driven narrative, and stunning visuals, effectively serving as the “Season Two” of the original Young Avengers.
The catalyst for Children's Crusade is not a single event, but the culmination of years of trauma, mystery, and burgeoning power.
The story's roots lie in the immense, unchecked power of Billy Kaplan, the Young Avenger known as Wiccan. As Billy's magical abilities grew, he became one of the most powerful sorcerers on the planet, a candidate for Sorcerer Supreme. However, his control was tenuous. After a single thought nearly neutralized a group of Sons of the Serpent terrorists, the Avengers became deeply concerned. They saw in Billy's untrained reality-warping a terrifying echo of the Scarlet Witch, the woman whose breakdown led to the deaths of several Avengers (including The Vision and Hawkeye) and the near-extinction of mutantkind. For Billy and his twin brother Tommy (Speed), the connection was personal. They were the reincarnated souls of Wanda's lost children, a fact that drove their desire to find her. They believed she wasn't a villain, but a broken woman who had been manipulated and was in need of help. They theorized that if they could find her, Billy's immense power could potentially cure her amnesia and reverse the Decimation. The final push comes when a new Master Pandemonium attacks the Young Avengers. During the battle, Wiccan's powers flare out of control, forcing the Avengers to intervene. Fearing the Avengers would take Billy into custody for “testing” and dissection, the Young Avengers decide to go on the run. With a cryptic clue from Magneto, who also desperately sought his lost daughter, their quest began: a “crusade” to find the Scarlet Witch and save her, regardless of the consequences and in direct defiance of the most powerful heroes on Earth.
As of now, the Children's Crusade storyline has not been adapted in the MCU. The narrative framework and character relationships of the MCU differ significantly from the comic canon that sets up this event. However, the MCU has laid substantial groundwork that heavily borrows from the themes and character dynamics of Children's Crusade:
A future MCU adaptation would require significant changes, but the core emotional story—of children searching for a lost, powerful, and misunderstood mother—remains a potent possibility for a future phase of the cinematic universe.
The narrative of Children's Crusade is a globe-trotting, super-powered manhunt that escalates from a personal quest into a world-threatening crisis.
The crusade kicks off with the Young Avengers, led by Wiccan, going rogue. Their first stop is a facility where the original Vision's body is held, hoping to find a clue. They are immediately intercepted by the Avengers. The confrontation is tense, with Captain America (Steve Rogers) and Iron Man trying to reason with the kids, while others, like Wolverine, advocate for a more direct, even lethal approach to preventing another Scarlet Witch-level disaster. The standoff is broken by the arrival of Magneto. He reveals his grandfatherly connection to Wiccan and Speed and offers to help them find Wanda, arguing that family should stick together. Despite their deep mistrust of the Master of Magnetism, the Young Avengers accept his help and escape with him, officially becoming fugitives.
Guided by Magneto, the team travels to Mount Wundagore in Transia, Wanda and Pietro's birthplace. There, they are ambushed by Quicksilver, who is furious with Magneto for involving the children. Pietro reveals he also searched for Wanda and found a woman matching her description in a nearby village. The reunion is shocking. They find a powerless, amnesiac Wanda Maximoff living a simple life in the village, seemingly with no memory of her past as an Avenger or a mutant. She is engaged to be married. As the team tries to jog her memory, they are attacked by a squad of Doombots. The true architect of the situation is hinted at, but before they can process it, Wolverine and the Avengers arrive, leading to a massive three-way battle between the Young Avengers/Magneto, the Avengers, and the Doombots. In the chaos, Iron Lad (a younger Kang the Conqueror and founder of the Young Avengers) returns from the timestream, bringing with him the new Stature (Cassie Lang) and a reprogrammed Vision. Iron Lad teleports the team and Wanda away from the battle and into the timestream.
Iron Lad's goal is to go back in time to prevent the events of Avengers Disassembled. However, a distraught Wanda stops him, stating that even if she is a monster, she cannot allow the past to be rewritten. Her emotional outburst causes her to regain her memories and her full, god-like powers. She teleports the group to Latveria, directly confronting Doctor Doom. It is here the central mystery is unraveled. Wanda reveals that on the eve of Disassembled, she sought Doom's help to resurrect her lost children. Doom, a master of both science and dark magic, attempted to help her channel the cosmic “Life Force” to achieve her goal. But the power was too immense for a mortal mind to contain. It overwhelmed Wanda, shattering her sanity and causing her to lash out at the Avengers. Her subsequent reality warp in House of M was a side effect of this possession. Doom then took advantage of her broken state, whispering in her ear and manipulating her to his own ends before wiping her memory and hiding her in Latveria, planning to one day claim the Life Force for himself.
With her mind restored, Wanda is consumed by guilt. She successfully purges the external Life Force from her body with help from Wiccan and Doom. Seeking atonement, she offers to undo her greatest sin: the “No More Mutants” spell. The X-Men, led by a hardened Cyclops, arrive on the scene, demanding Wanda be turned over for justice. This leads to an epic confrontation: The Avengers vs. The X-Men vs. The Young Avengers, all centered on the fate of Wanda and the future of mutantkind. As the battle rages, Wanda and Wiccan begin a complex spell to restore the powers of all willing mutants. However, Patriot (Eli Bradley) fears her power is still unstable and shoots an arrow at her to disrupt the spell. Magneto intercepts it, but the distraction allows Doctor Doom to make his move. He ambushes the group, stealing the Life Force for himself and becoming a god-like being. The combined forces of the Avengers and X-Men are powerless against the omnipotent Doom. He offers to use his power to solve all the world's problems, but under his absolute rule. As he casually defeats the heroes, Stature (Cassie Lang) makes a desperate, heroic charge against him. Doom dismisses her with a single energy blast, killing her instantly. Witnessing Cassie's death fills the Young Avengers with rage. Wiccan, pushed to his limit, unleashes his full potential as the Demiurge, a being with the power to rewrite reality itself. He successfully strips the Life Force from Doom, and together, he and a weakened Wanda use the power to resurrect Scott Lang (Ant-Man), Cassie's father, as a final gift to their fallen friend.
The fallout from Children's Crusade was significant and far-reaching:
The emotional core of the story. Their “crusade” is born of youthful idealism and fierce loyalty.
The voice of authority and caution. Having lived through Wanda's breakdown firsthand, they see her as a planetary threat and the Young Avengers as reckless children playing with fire.
The victims of Wanda's greatest crime. For them, this is not about redemption; it's about justice.
The central question of Children's Crusade is: Can Wanda Maximoff be forgiven? The story reframes her past actions, shifting the blame from pure madness to external manipulation by Doctor Doom. This complicates the narrative, forcing characters and readers to grapple with degrees of culpability. Is a person responsible for their actions if their mind was compromised? The X-Men say yes, the Young Avengers say no, and the Avengers are caught in the middle. This exploration of trauma, mental health, and responsibility is the story's most mature and enduring theme.
The event is a stark clash between generations. The Young Avengers operate on pure, unblemished idealism. They believe in second chances and see a broken person who needs saving. The adult heroes—the Avengers and X-Men—are jaded by experience. They have seen what Wanda's power can do and prioritize global security over the potential for one person's redemption. This conflict highlights the eternal struggle between the hope of youth and the cynicism that comes with age and trauma.
Family is the story's driving force. It's about two sons searching for their mother. It's about a grandfather (Magneto) and an uncle (Quicksilver) trying to salvage their broken family. It's about the found family of the Young Avengers willing to defy the world for one another. And it's about the sins of the “father”—Doctor Doom's manipulation—visiting tragedy upon the “children.” The narrative powerfully argues that family, whether by blood or by bond, is a force capable of both healing the world and breaking it.
While a direct, one-to-one adaptation is unlikely, Children's Crusade provides a compelling roadmap for the future of the MCU's mystical and street-level narratives.
Ultimately, the emotional core of Children's Crusade—a new generation of heroes trying to heal the wounds left by the old—is a timeless theme that fits perfectly within the ongoing narrative of the MCU's post-Endgame world.
