[8] Mesmero later joins Weapon X, whose director enhances his powers, enabling him to control entire crowds of people at once.

[12] Mesmero finally achieves a personal triumph by forming a relationship with a woman who had saved his life, promising to somehow help her in turn.

[13] Mesmero eventually returns to villainy, becomes the leader of the Brotherhood of Evil Mutants, and regains his powers under unspecified circumstances.

He had proven unable to control Magneto, which his helmet that negates all telepathic attacks pertain brainwashing[16] and Alysande Stuart, with her capabilities,[17] for unknown reasons.

That feat was only used for escaping an angry Alpha Flight and may have been controlled entirely by the technology of this suit or tied in some way to his mental capabilities.

[20] Early after the formation of the team, Mesmero was killed and his body remained in the Timebreakers' fallen heroes gallery in the crystal palace.

[22] In the Age of Apocalypse timeline, Mesmero joined with a group of telepaths to create a "psychic pyramid scheme" known as the Overmind which leader Quentin Quire uses to empower himself.
