I chose Deadends body because it looks like he has a bit of a tail on his back.
Megatron thought that Trypicon was in stasis....well he was sort of. His massive body was in stasis but only because he downloaded himself into a smaller body before the Autobots tore him up into pieces. Trypticon went into hiding from Megatron and started to upgrade himself. He has increased speed now, something he is NOT used to lol.
