Vertigo

Vertigo is a native of the Savage Land who obtained superhuman powers at a young age by genetic engineering. Her powers enable her to render a person severely dizzy and even unconscious.

She was initially a member of the Savage Land Mutates, empowered by Magneto, with whom she first battled the X-Men and Spider-Man.

Later, although not a mutant, she joined the Marauders, a group of mutants working as assassins for the enigmatic geneticist known as Mister Sinister. Sinister wanted his assassins to destroy a large community of mutants, known as the Morlocks, who lived under New York City, as he had deemed them genetically useless. The Marauders did succeed in annihilating a large number of the underground mutants. While the Marauders were accomplishing this, they also clashed with the X-Men, X-Factor, Thor, and Power Pack. With the Marauders, she also attempted to kill Madelyne Pryor.

Sinister later sent Vertigo along with the other Marauders to fight the X-Men in New York City just before the extra-dimensional incursion known as the "Inferno". She was apparently killed in battle with the X-Men. Her alliance with Sinister was short-lived at that time, as she soon rejoined her Savage Land Mutate allies.
