Other Info 
Anthropologist Dr. Bolivar Trask saw mutants as a threat to humanity. Ironically, Bolivar had two children who were born mutants: Larry and Tanya . Larry had powers of precognition and Tanya could travel through time. (To learn about Dr. Trask's children, click on their highlighted names above.)

At one point, when Dr. Trask was publishing anti-mutant articles, he engaged in a public debate with Charles Xavier about human/mutant relations. Xavier argued that mutants were just like humans and not evil. However, Trask was not convinced and ended up revealing his mutant-hunting robots: Sentinels. However, when Trask activated the Sentinels, a few rogue Sentinels actually kidnapped both Xavier and Trask and brought them to Master Mold (the main robot that created the Sentinels). Master Mold had decided that humans and mutants were inferior to robots and coerced Trask to construct Sentinels for him instead.

Eventually, Xavier summoned his X-Men which resulted in a fight between the X-Men and the Sentinels; however, Beast was captured. To reveal the X-Men's secrets, the Sentinels told Dr. Trask to use a device to read Beast's mind. When Trask did so, he discovered that the X-Men were mutants who were actually trying to protect humanity. Realizing that he was wrong about mutants, Dr. Trask decided to help the X-Men in defeating the Sentinels. To do so, Trask sacrificed himself to destroy the entire Sentinel base.

Later, the Purifiers--under the orders of Bastion--resurrected Trask (using Technarch technology) to be part of a team of the world's foremost mutant killers. Dr. Trask was reported to have the highest record of mutant kills--16,521,618. (To learn about the team and/or character above, just click on their highlighted names).

Bolivar Trask makes an appearance in third X-Men movie: X-Men: The Last Stand. In the movie, "Trask" is the head of the Department of Homeland Security and seems to have no connection to Sentinels. In addition, the movies changed the ethnicity of Trask from Caucasian to African American. UPDATE: An actual Bolivar Trask appears in the movie, X-Men: Days of Future Past.
