The Decepticons then stole the entirety of the Autobots’ fuel supply and attacked them once more.
But Optimus, having anticipated a trick on the Decepticons’ part, arrived at the battlefield with a new supply of fuel for his troops.
Starscream's scheming was a constant throughout the Earth conflict, and it culminated in his expulsion from the Decepticon ranks, following which he created the Combaticons to serve as his personal army, only to have them turn on him, forcing him to rejoin Megatron's ranks. Following Megatron's climactic battle with Optimus Prime in 2005, Starscream set his commander's battered body adrift in space and promptly appointed himself the new Decepticon leader.
In the midst of a grandiose coronation ceremony, however, Megatron returned, recreated as Galvatron by the power of Unicron, and promptly blasted Starscream to ashes.
He and Thundercracker employed Sleep Nets to capture Bluestreak and Sideswipe.
As the Decepticons incarcerated the Autobots, Starscream expressed concerned that they had missed one; Bumblebee was nowhere to be found.
Even on the few times he has taken command of the Decepticons, he quickly loses control of a situation, but is too arrogant to realize when he's in over his head.
