Starscream Supreme

Starscream Supream was created by Starscream as an attempt to literally blow Megatron away. When Lugnut lost control of the Supream clones, somehow a program Starscream left behind took control, and activated a bomb inside of the clone's spark chambers, just like his first attempt at cloning himself. The bombs would have exploded at a range of 100 miles, killing all Decepticons, Autobots and humans caught in the blast. One clone was defeated by Omega Supreme, and the other one was caught in it's own blast, which was sheilded by a forcefield created by the Allspark that Prowl and Jazz recreated from the fragments.
