the other Decepticon Seeker jets, many of whom share his physical design. His technical specifications indicate top speed as Mach 2.8 and altitude ceiling as . Launchers mounted on his arm (under his wings in jet mode) can deliver cluster bombs capable of leveling a area and fire his signature null ray, which for brief periods disrupts the flow of electricity in any circuitry it contacts. This action temporarily renders inoperable any electronic device or machine, including Transformers. Animated series Generation 1 Starscream was formerly a scientist and explorer, working with the future Autobot Skyfire, during the Golden Age of Cybertron, shortly before the Autobot/Decepticon war re-erupted. Following the disappearance of Skyfire when the two were exploring a prehistoric Earth, Starscream returned to Cybertron and soon abandoned his scientific pursuits, becoming a warrior in Megatron's Decepticon army as the civil war exploded. Starscream attended the Cybertron War Academy, mentioned in the episode "A Prime Problem". Starscream makes use of his old scientific profession in a few episodes. For example, in "A Decepticon Raider in King Arthur's Court", when he and several other Decepticons were temporarily displaced in time to medieval England, the weapons of the Transformers ceased functioning; Starscream knew how to use available materials to create gunpowder as a substitute for himself and the other Decepticons. In "Starscream's Brigade", he attempts—in what was then only his latest in a series of attempts—to overthrow Megatron as the leader of the Decepticons. After being defeated and exiled in Guadalcanal, Starscream finds the remains of some World War II military vehicles, which inspire him to create an army of his own. He travels to Cybertron using the Space Bridge, forcing the guards and eluding Shockwave to do so. He breaks into the Decepticon Detention Center and steals the five personality components of Renegade Decepticons, then installs them into five wrecked military vehicles and they become the Combaticons. The Combaticons (who combine to form Bruticus) and Starscream then capture four Transformers. When Megatron rallies his troops (except the Stunticons) against Starscream and the Combaticons, he deploys Devastator to fight Bruticus, but Devastator is defeated. Megatron attempts to retreat, however Starscream orders Bruticus to capture Megatron and hold him while he gloats and humiliates him. While this is going on, the Stunticons arrive, combine into Menasor and defeat Bruticus. Megatron then orders Astrotrain to exile Starscream and the Combaticons to a distant asteroid. In
