A purple-skinned mutant with the power to teleport, Blink sacrificed herself to save members of Generation X from the Phalanx. Years later she was resurrected by Selene & turned into a killer. A popular character in the Age of Apocalypse, Blink's alternate universe adventures continued in the Exiles.
She has proven many times to be a skilled hand-to-hand fighter, and it is unknown whether her enhanced agility is the result of simple training or a consequence of her mutation.
Blink also has a somewhat unusual appearance with lilac skin, dark pink hair, pointed ears and pupil-less green eyes (this was a change in Exiles: both MU and AoA Blink had white eyes with a blue sheen). She also has pink marks across her face: these were present at birth, and are not scars, tattoos, etc.
