NAME: Sentinel
AFFILIATION: Sentinel program
SPECIAL ABILITIES: Mutant tracking
BACKGROUND: Scientist Boliviar Trask, as a way to stop the perceived mutant threat to humanity, created the original Sentinels. Trask received government-funds to research his work into eliminating mutants and this was the Sentinels prime 
objective. Trask was invited to debate Professor Charles Xavier, one of the world’s strongest mutants, in a televised debate on mutant-human relations. Trask remained unconvinced of the lack of threat most mutants posed and revealed his Sentinels to the world. The robots then kidnapped Trask and took him to their leader, Master Mold, where Trask was directed to create more.
Eventually, after Trask was given a mindscan of the X-Men who came to rescue him, he realized that mutants were peaceful and that the Sentinels had to be destroyed.
Trask then sacrificed his life to stop the Sentinels and Master Mold in a massive explosion. Other Sentinels have been created and reprogrammed by numerous people including Sebastian Shaw of the Hellfire Club, Bastion, Cassandra Nova and Apocalypse.
