X-Men
Robert Kelly was a U.S. Senator and a major proponent of the Mutant Registration Act. He was captured by Mystique (impersonating his aide Henry Gyrich) and Toad and taken to Genosha as a prisoner. There, he was transformed into a mutant by Magneto's radiation machine.

Using his new-found abilities, Kelly escaped Genosha and eventually arrived at the X-Mansion to receive help. However, the unnatural mutation created by the radiation of Magneto's machine caused his cellular structure to break down. He later de-molecularizes into water and was last seen alive by Storm.

Mystique survives her injury from Wolverine at Liberty Island, impersonates Senator Kelly and calls off the Mutant Registration Act. The X-Men notice her impersonation as Senator Kelly on TV.

Kelly, now impersonated by Mystique, gives others the impression that he is now more supportive of mutant rights.
