Starscream (G1)

Originally a scientist on Cybertron, Starscream was kept out of the Autobot-Decepticon war by his best friend Skyfire (Jetfire). However, on a scouting expedition to what would become the planet Earth Skyfire became lost and Starscream slowly surrendered to his darker urges eventually he betrayed the Autobots and science and joined the Decepticons. Unfortunately, only power drove Starscream to join the Decepticons and he attempted to overthrow his leader Megatron many times. In 2005 after the Battle for Autobot City, in which Megatron was gravely wounded, Starscream usurped Megatron by throwing him and the other wounded Decepticons (mostly the ones he didn't like) out of Astrotrain. On Cybertron his coronation was interrupted by Megatron, now known as Galvatron, who insulted then killed Starscream. However Starscream was restored by Unicron and then blasted into space by the Autobots where he landed on the world of Minecraft and swore to take revenge on Galvatron. However, if need be Starscream can contact his fellow Seekers Skywarp and Thundercracker for assistance, or to just do his work for him.
