I want to say something about Optimus that you'll probably wont like. I dont think he was all that much of a badass. Okay, in transformers 1 he needed Sams help to kill Megatron because he was getting mauled by Megs. In Rotf he was kicking Decepticon tailpipe, but he still needed Jetfires parts to defeat The Fallen and Megatron. I will admit that, but in Dotm he got nearly killed by Sentinel. My point is Optimus always seems to have to get some type of help to beat the main antagonist.
