Not Skywarp? He's the one actually in the Joe book...
(for my 2 cents, I'm mostly happy with the Hasbroverse so far - but then, I'm a Joe fan primarily. Got a new book for them, plus M.A.S.K. and Revolutionaries to keep my Action Man fix, that's a win for me. Lost track of the IDW's Transformers stuff years back and haven't felt the need to try again; most of my fondness for that universe is based on the 'robots staging covert war while disguised as vehicles among us' conceit, so the increasingly sprawling space opera they've become holds little appeal.)
