Optimus Prime is K.A.R.R.!
Wow, I was watching Knight Rider: Knight to King's Pawn and could not believe my eyes when they merged this with Transformers.
K.A.R.R. is the evil version of K.I.T.T the talking car. Apparently K.A.R.R. can transform from a car into a robot just like an Autobot. To make it even more interesting they used Peter Cullen for the voice of K.A.R.R. He is the voice actor who does the voice of optimus prime.
At first glance this is the stupidest thing ever… I was totally wrong, it was so awesome!!! Recipe for a fun time =
