OMEGA SENTINEL, like OMEGA SUPREME, is one of the legendary Guardians of Cybertron. He is commander of the Guardians, who feels that his only purpose is to protect and defend. His primary programming has made him a stoic figure devoid of emotion. He will analyze a battle situation using logic and, when necessary, brute strength.

He believes that these qualities are a tactical key to victory when battling the DECEPTICON forces.
