Psylocke (Mei Melançon)

When the mutant "cure" was created, Psylocke joined the Omegas and protested, saying that there was nothing wrong with mutants and therefore, nothing to cure. Callisto decided to join Magneto's Brotherhood of Mutants. The rest of her group, which included Psylocke, Quill, and Arclight, followed, and became prominent members of the Brotherhood.

Psylocke and the Omegas participated in the battle of Alcatraz Island where she, Quill, and Arclight entered Worthington Labs while the rest of the mutants fought outside. Psylocke helped capture Warren Worthington II, and attempted to kill him by throwing him off the balcony. However, his son saved him before he could hit the ground. When Phoenix began to destroy Worthington Labs with her disintegration wave, Psylocke and the rest of her teammates ran out and died.
