Ok, who will kill Megatron if he's done in? Optimus - Makes the most sense. They're old arch enemies and this could be how their feud ends. Ratchet - Unlikely, but could happen. Bumblebee - Payback for his voicebox. Smokescreen - He's destined to be the next Prime. He could get his moment of glory by ending the war. But, I feel his glory moment will come in the movie. Predaking - A lot of people's favorite choice. But, he left and fought Megatron in 'Synthesis'. I think his chance has passed. But, he could still very easily do it. Starscream - Tired of all the abuse, he seizes his opportunity and returns to his old ways. Other - Please explain in the comment section who you think does it and why if you vote other.
