Ack! Denied. I thought you were referring to the Transformers Prime cartoon circa 2010-13, rather than the G1 cartoon. Silly me.

As for the next question; I think it was Camshaft. One of those mail-away exclusive bots who never appeared in the cartoons nor in toy-form on general retail (I'm also trying to answer these as soon as I see them, without looking up the answer. I'm guessing that's one of the rules).
