As a comics fan long before I was a wargamer, and a wargamer now most of my life, I am an irredeemably dedicated fan of the SuperSystem superhero/supervillain miniatures skirmish game, and of the game-specific line of Superfigs miniatures which accompanies it (the dedicated SuperSystem website seems to be down presently; information--as well as a tremendous variety of play-aids--can be had at the SuperSystem Annex and award-winning miniatures painter Agis Neugebauer has a showcase of his Superfigs work.
Great as Superfigs are, one can never have too many four-colour hero and villain models. Reaper Miniatures has some dedicated candidates in their wonderful--and wonderfully diverse--Chronoscope line (how I would love a shot at developing a coherent miniatures skirmish game out of *this* collection of models!), but it is their more recent Pathfinder Fantasy series which has my current attention: ostensibly Paizo's 'D&D 3.5+' fantasy system, the Pathfinder world must have a great deal more than traditional dungeon-delving going on, if these epic good guys and bad guys are wandering around in it! I have used links to Paizo's site as I have used them often through the years (and they offer a discounted price on most of the miniatures in question); if you want to see more and/or order directly from the source, Reaper has a great reputation for customer service, as well, and you can start at http://www.reapermini.com.
Grey Gardener (a pulp masked hero if ever one walked down a shadowy alley)
Red Mantis Assassins (male and female)
Plague Doctor (especially suitable for a pulp campaign)
Skinspawn (a perfect henchman for the above)
Whispering Tyrant (the figure which of them all just radiates 'master villain')
I hope some of this piques curiousity about SuperSystem--I know I could use more opponents, and more Friendly Local Game Stores (FLGS) willing to carry the line!
