Any generation, doesn't matter. I'd have to say mine is...probably Abominus. I dunno, just really like the idea behind him and such, he's badass. I really do need to see about picking him up some day, is there a reissue of him at all or do I need to browse around for a nice deal on a vintage (or a gift set...)? Anyways, besides him I think Bruticus or Menasor would be my second favs.
