Archer led an away team to take control of the "Defiant" while the "Enterprise" was destroyed by the Tholians. He and his team, plus survivors from the "Enterprise", discovered the "Defiant" was not only from another dimension, but the future and that the alternate dimension never had a Terran Empire. After successfully crushing a rebellion against the Empire, Archer attempted to take the futuristic vessel to Earth where he would proclaim himself Emperor. However, before he could do so, he was killed by his universe's Hoshi Sato, who poisoned him, took the ship and claimed the Terran throne for herself.
