Juggernaut (X-Men: Evolution)

This version of Juggernaut was Xavier's half-brother, a mutant whose powers were awakened by mysticism. In this series, his strength and intelligence are significantly less than in other continuities, although he can still throw tanks and other vehicles, and he was still described as unstoppable. Some time prior to the events of the series, he had been defeated by Xavier and incarcerated in a high-security prison under the supervision of Captain Stone. He was permanently sedated to prevent him from breaking out, although during the series Mystique managed to free him on several occasions.

In his first appearance, he attempted to attack Professor X, so Mystique could steal Cerebro. However, he betrayed Mystique and was defeated through the combined forces of the X-Men and the Brotherhood. After this he was returned to his containment cell.

In his second appearance, his prison unit was sabotaged by Mystique to draw Xavier away from the institute: Xavier's presence was required to keep Juggernaut out of action while the prison was repaired. Although Juggernaut was kept sedated throughout the procedure and did not escape, Mystique used Xavier's absence to successfully steal a data disk with information on all of the X-Men and New Mutants.

In his third appearance, he went on a rampage while Xavier was left in his place in stasis in prison, leaving the X-Men to stop him from attacking a dam. He is defeated when Cyclops unleashes the full power of his optic blasts against their foe, giving Rogue a chance to steal some of his power. She then throws him into the air, allowing Iceman to freeze him into a block of ice, and he falls into the river.
