I can just imagine the meeting that took place re: Takara Beast Wars Metals - Megatron's design...
Boss man: So...Megatron. He's a T-Rex, that's pretty cool. But how can we make him cooler?
Staff member 1: Let's make him fly
Staff member 2: Yeah, make him fly and have wheels. That's how he rolls!
Boss man: Awesome idea's guys. I also suggest we position his fists close to his chest in alt mode so he can still punch people in the face
*cheers all around*
