Megatron is a heroic Predacon from the Shattered Beasts universe.
"Everyone has the right of freedom."
-Megatron responding to one of Primal's rants
Megatron is a kind, benevolent leader. He always treats his troops with the utmost respect and care, never considers cheating even when it looks like he'll lose. Now that he is being forced into a war against the Maximals he has vowed to protect all innocents.
Not to say he can't fight, he has the power of the original Megatron and he is a brillant stratigist and tactitican.
