After the Fallen was destroyed and Starscream spreading rumors that Megatron had abandoned his master to Prime, Megatron has been targeted by other Decepticons feeling that their 'Glorious' Leader does not deserve to be leader of the Decepticons.
But Megatron won't give up without a fight. As soon as he deals with his peers he'll deal with a certain treacherous Decepticon.
You may have went a little too far on the detailing. I'm gettin' lost look ing at it. But, otherwise great pic, great idea. Treacherous Decepticon-Starscream? Let me guess, even though it was his idea for them to leave, the moment they got back to base he started spreading the rumors!
I can actually feel the rage radiating from Megatron's eyes, and the head in his claws shows he means business!
