Wheeljack must have one of the weirdest Transformers robot heads there are... Two flaps for ears that glow whenever he talks, and some kind of mouthmask that no other transformer robot has.

Wheeljack is the mad scientist, ok, but why didn't any of his autobuddies try telling him that it might be a good idea to test his inventions a little before putting them to full use? Just because he's a loony, doesn't mean that everyone else should be.

Needless to say, Wheeljack was one of my least favourite Transformers.
