I believe Lim did work on Ex-Mutants when it was at Eternity Comics. I could be wrong. Ex-Mutants was great, loved the concept but the only stuff I read was when Malibu did it.
You are correct, sir! Lim penciled most of the first Eternity run (Have 'em all). Pelletier penciled the Malibu run up to the crossover (Genesis?). My run of the Malibu series is like DAP's undies: SPOTTY!
Lim's run is a hoot. That freaky cross-eyed guy with the 'fro cracked me up EVERY. TIME.
Ron also had quite a way with anatomy back then. Folks that cry foul over Liefeld's stuff should take a peek at Lim's early work. It's dripping with enthusiasm (Ewwww...) and THAT is the stuff that kicks it up a few notches higher than most of the books that flooded the market during the B&W boom. I'd never part with the run.
