I once drew a 20+ page spread of generic Gobots fighting generic Renegades. I was 10 or 11 then, so I guess that makes me a closet fan.

But the only episode I liked (probably the only one I watched too) was the one about them finding ancient Machine Men in the centre of Gobotron (was the episode called "The Gobots / Renegades that Time Forgot" or something like that?).
