"The mutant threat is the defining issue of our time. We can choose to stem the impending tide of extinction or we can stand by passively and allow it to wash away any remnants of our species."
―Bolivar Trask[src]

Bolivar Trask is the owner of Trask Industries and created the Sentinels.


X-Men: Days of Future Past

Bolivar Trask was one of the world's leading weapons designers in the early 70's, but after the mutant involvement in the Cuban Missile Crisis, Trask covertly began performing experiments on mutants, using their abilities to further his own research. He believed that the only response to the perceived mutant threat was to eradicate it. As a response he created the Sentinels, robotic mobile weapons platforms that seek out and target mutants. In 1973, Trask met with Congress to lobby for implementation of the Sentinel program. However Senator Brickman argued that it would be pointless to target the mutants since they only represent about a tenth of a tenth of a tenth of the population. The decision is made to shut down the project, to Trask's displeasure.

Trask's experiments caught the attention of Mystique. When infiltrating Trask Industries while disguised as Trask, she discovered files showing Trask had experimented on the corpses of several mutants, including Angel Salvadore and Azazel. Unaware of Mystique's investigation, Trask headed to the Paris Peace Accords to present his program, and blueprints for the Sentinels to the foreign officials there, along with Major William Stryker, Jr.. Trask, who was carrying a device that could detect the presence of mutants, then discovered Mystique, who was disguised as a Vietnamese general.

Original Timeline

X-Men: Days of Future Past

Mystique murdered Trask by shooting him in the head. Moments later she was incapacitated by Major Stryker. Trask's murder impressed on world governments the need for the Sentinel project. Analyzing Mystique's DNA over fifty years, the Sentinels were upgraded to be able to adapt to the powers of any mutant.

New Timeline

X-Men: Days of Future Past

Before Mystique could fire, Wolverine, Xavier, Hank, and Erik arrived to stop her. Trask managed to escape during the commotion.

Following the near assassination, Trask, Stryker, and other officials met in the White House as news reports of the mutants' sightings were shown on television. Trask convinced President Nixon that someone like Mystique can easily impersonate a Secret Service agent or even the President himself and order a nuclear strike. Nixon allowed for the Sentinel program to receive the proper funding. Trask's scientists found Mystique's blood on the street and took it as a sample, and Trask requested that Mystique be taken in alive, so he can study her DNA.

On the day of the unveiling of the Sentinels at the White House, they began to activate as Magneto is controlling them with the train track metal he secretly inserted into them the night before. Mystique, disguised as a Secret Service agent, grabbed her gun and started walking towards Trask, but Xavier stopped her. Everyone fled as the Sentinels began firing, and the Secret Service took Nixon, Trask, and Stryker into the safe room in the White House, unaware that Mystique was among them.

Erik then pulled the safe room out of the White House. After giving a speech, Mystique, disguised as Nixon, came out to stop him, shot and grazed him through the neck with a gun, and then knocked his helmet off to take him down. She then aimed her gun at Trask, ready to kill him. Xavier once again pleads with her to reconsider but says that the decision is ultimately hers. Mystique drops the gun and leaves.

Later, a newspaper article mentioned that Trask was arrested for selling military secrets, likely from having pitched the Sentinel program earlier to the foreign officials at Paris.

A mid-credits scene in The Rogue Cut reveals that Trask is imprisoned in Magneto's former cell beneath the Pentagon.
