Starscream

"Not to call you a coward, master. But sometimes, cowards do survive."
- Starscream convincing Megatron to retreat. Leading the hunt for the AllSpark during the absence of Megatron on Earth has given Starscream a taste for command. He has experienced firsthand the brutality that allows Megatron to maintain control over his Decepticon legions. He craves ultimate control, and looks forward to the day when Megatron makes the mistake that allows Starscream the opportunity to slip a jagged shard of steel between his processors and become the new leader of the Decepticons.
