Senator Robert Kelly appears in Marvel: Ultimate Alliance
Robert Kelly was born in Philadelphia, Pennsylvania on June 28, 1946. As member of the U.S. Senate, Robert Kelly long regarded the growing number of mutants as a threat to national security. To cope with this supposed danger, he promoted legislation such as the Mutant Registration Act, requiring those with powers of genetic origin to disclose their abilities to the government. This proposal prompted the second Brotherhood to attempt to assassinate Kelly in Washington, D.C. The Brotherhood did not succeed, thanks to the intervention of the X-Men.
The failed assassination attempt fueled the Senator's resolve to pass the Registration Act. He cultivated a partnership with industrialist Sebastian Shaw, who built mutant-hunting Sentinels and supported Kelly's plans. Unbeknownst to the Senator, Shaw was a mutant and the Black King of the Hellfire Club. Following one of his meetings with Shaw in New York, the Senator's limousine was demolished by debris from a fight involving the X-Men. Kelly survived -- but his wife, Sharon, died in the wreckage. Kelly's grief strengthened his position that mutants were too dangerous to be allowed to run rampant, and he ordered the production of more Sentinels
Kelly supported "Operation: Zero Tolerance" until he realized the android known as Bastion, programmed to exterminate mutants, was using the program to convert innocent humans into Sentinels and trampling on the rights of U.S. citizens. When he withdrew his support, the Senator became one of the Sentinels' targets. To save his life, he called on the X-Men and wielded his political influence to enlist the worldwide intelligence and peacekeeping organization S.H.I.E.L.D. to shut down Bastion. His political views unaffected by the experience, Kelly declared his candidacy for president on an anti-mutant platform.
Marvel: Ultimate Alliance: Story
He is captured by Arcade and is imprisoned somewhere in Murderworld (he is located in the cart to the left when exiting the fake Castle Doom). A side-mission involves searching for him in Murderworld.
If he is found, he will support the Mutant Aid Bill which will allow government funds for schools (similar to Professor X's) which will be successful in training young mutants in how to control their powers.
If he is not found, he achieves freedom on his own and successfully sponsors a bill where all mutants are sent to re-education camps where they will be brutally educated to not use their powers.
