Starscream

Starscream, also known as Commander or Lord Starscream and nicknamed Screamer by the other Decepticons, is Megatron's 2nd-In-Command during the War For Cybertron. As a Decepticon, Starscream was loyal to Megatron but always tried to become the leader of all Decepticons. During the Attack on the Nemesis, Starscream did get what he wanted, but his brothers saw the opportunity to lead the Decepticons as well, and he reluctantly allowed them to share the leadership position with him. When they arrived at Earth with the Nemesis, Starscream told every Decepticon (except the Vehicons) to get an Earth-vehicle form. All of the Decepticons did and Starscream, Thundercraker, and Skywarp all have an F-16 Harrier Jet. Later, Megatron returned as Galvatron with the Combaticons' help. Galvatron fought Starscream but as usual Starscream called on bigger backup which was the Leaper that had challenged Megatron before. While the Leaper fought Galvatron, Starscream and his brothers left the scene becoming rogue Decepticons.
