The KISS comic was cool because Gene Simmons was actually a comics fan..in fact, selling comics was one of his earliest money-making schemes. Well, as much as he is a fan of anything, the two biggest things he a fan of is sex and money (not necessarily in that order).
The Micronauts were awesome and the toys were really cool as well. I'm kinda surprised they haven't been brought back. They were sort of the forerunners of other toys to comics/cartoons franchises.
Rom was a really good character written by the very underrated and very tragic Bill Mantlo, was was Micronauts.
