Omega Sentinel is immense -- immensely strong, immensely logical, and immensely powerful. Once sent to Earth to locate the missing Omega Supreme, the Omega Sentinel was found instead by the Decepticons, and lent his awesome firepower to their cause. Megatron described him as a cross between Shockwave's mind and Devastator's power. Although not as ambitious as Shockwave, the Omega Sentinel was also loyal only to his sense of logic, and would switch allegiences at a moment's notice if his analysis dictated it. The Omega Sentinel's deep devotion to logic made dealing with the highly emotional human populace of Earth difficult at times. Fortunately, as a Decepticon, the Sentinel could simply destroy anything that struck him as illogical and be done with it.
