This armor eventually achieved sentience due to Stark downloading Jocasta into the armor, a strike from Whiplash's whip and the armor's lack of Y2K compliance. This corrupted the usual failsafes Stark had installed to prevent such an occurrence happening as Jocasta unintentionally infected the armor with the 'Ultron Imperative,' a system that would cause Ultron's creations to rebuild him if he was ever destroyed. Lightning strikes sustained during a fight with Whiplash providing the necessary 'nudge' to push the armor into full sentience based on Stark's own mind.
