|Senator Robert Kelly|
- "Ladies and gentlemen, the truth is that mutants are very real, and that they are among us. We must know who they are, and above all, what they can do!"
- ―Senator Kelly
Senator Robert Kelly was a human turned-mutant and the main proponent of the Mutant Registration Act.
Robert Kelly was a US 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.
