Sentinel is a robot devised by UNECOM's biggest brains, including Anya Turgenova. It is highly intelligent and heavily armed but sadly all involved skimped on the fail-safes. Presumably no-one involved read Avengers comics.

As the latest technological advance in human weaponry for the battle against the Renegades, UNECOM proudly unveiled Sentinel with the Guardians present. Scooter then helped hook it up to the sum total of human knowledge, at which point it decided to kill all mankind. Obviously there was no way to switch the thing off and Sentinel brushed off the Guardians' attempts to deactivate it. Sentinel decided it had to eliminate all organic life on Earth as inferior, broadcasting this plan to the planet's population for no clear reason. Its' claim of total intelligence took another knock when it fell for Cy-Kill's usual pitch about it being best if they worked together, and the Renegades joined it in attacking Chicago. Leader-1, Turbo and Scooter - unable to get reinforcements from GoBotron due to solar flares - tried to stop Sentinel but were unable to even slow the robot down, and it buried the Command Center under rubble when Matt Hunter, A.J. Foster and Nick Burns attempted to attack with the craft's weaponry. Scooter resorted to projecting a hologram to feign defeat. While the Guardians recovered Sentinel and the Renegades devastated New York, Washington, D.C. and Boston. Such was the carnage that Blaster and Heat Seeker volunteered to brave the solar flares to bring the Power Suits to Earth. Courageous fought Sentinel in the Grand Canyon but the robot was a match for even the Power Warrior. However, Leader-1 pointed out to Sentinel that the Renegades were impure themselves, having organic brains. Infuriated, Sentinel turned on his former allies, chasing them off into space and leaving Earth alone. Sentinel
