Starscream once led the Cybertronian High Guard, waging a long and arduous guerilla war to destroy the evil forces of Sentinel Prime. Volatile and easily provoked, but cowardly when things start really going bad, Starscream's "might makes right" philosophy often brings him to blows with trespassers, pacifists, or people who just don't agree with him. Starscream believes the idea of a unified Cybertron is a myth because all that counts is the strength of one bot over. He lost command to D-16.
