Charles Xavier II

Charles Xavier II is an alternate reality mutant who is currently imprisoned in Earth-616.

Biography
Charles II is the child of Charles Xavier and Mystique who was apparently conceived while she was in the form of Moira MacTaggert. Charles II was given up at birth and left to make his own way in the world after accidentally killing his adoptive mother when his powers emerged. He eventually tracked down his birth mother, but by that time, she had been killed and replaced by his half-brother, prompting the two to join forces.

Believing that the current team of X-Men disgraced his father's dream due to their divided state since his father's death, Charles II telepathically took control of various members of the X-Men and recruited them into his new Brotherhood, allowing them just enough control to realize what was happening to them even if they couldn't fight it. He attempted to undo some perceived damage that had been done by going back in time to force the temporally-displaced young X-Men to return home, but this plan failed, resulting in Charles II beign paralyzed when he was stabbed by Colossus.

Eventually, the Brotherhood were able to find the young X-Men at Cyclops' new school, but their attacked failed due to Jean Grey's new ability to absorb telepathic energy and use it against others, allowing her to break the Brotherhood of Charles II's control and defeat him. He was subsequently imprisoned by S.H.I.E.L.D. with a telepathy-blocking collar, preventing him from using his powers.

Powers
Telepathy: Charles II demonstrated powerful psychic abilities and prowess in both offensive and defensive uses of his telepathic ability. It is unclear whether his powers rival those of his father, but he was able to block a young, but still extremely powerful, Jean Grey from reading his own and others' thoughts. His level of control appears to be refined enough to use Cerebro, as he did when searching for the young Scott Summers and Jean Grey. Yet, reflecting his more malevolent personality, Charles II favors, and apparently excels in, the field of mind control, as was shown by him simultaneously controlling all the members of the Brotherhood.

Weaknesses
Paraplegia: After being stabbed by Colossus with the Soulsword, he has suffered from paralysis from the waist down.
