Damn this is very cool like the title says All Hail Megatron!Awesome.My favorite Megatron incarnation is G1 (Of course)TF Prime's megatron,IDW Megatron and the war within Megatron.To be honest in my opinion you don't have to put color to it.It rocks just like it is.
Isn't Beast Wars Megatron supposed to be the smallest?
Anyways, love this group pic! I'm having trouble figuring out who the Megatron is that's standing between G1 and Animated. I want to say Galvatron because of the pattern on his belly, but the helmet looks like G1 Megatron's.
