Starscream is a fictional robotic character in the Transformers franchise produced by the American toy company Hasbro and the Japanese toy company Takara Tomy. He is the second-in-command of the Decepticons, a villainous faction of alien robots that seeks to conquer their home planet of Cybertron and the rest of the known universe. As with all Cybertronians, Starscream can disguise himself by transforming into vehicles, in his case a fighter jet, and he is usually portrayed as a treacherous and cowardly air commander who seeks to overthrow the Decepticon leader Megatron and assume control of the Decepticons.
