I've got to admit, I'm enamored with Heroclix, but I have absolutely no clue how to play the game. The figure assortment allows for molded bits of plastic featuring characters who otherwise don't exist in the round. It also features tons and tons of characters that saturate the market otherwise, but it's a nice additional niche for comic fans to dip their collecting toes into.
I'll occassionally pick up a 'Clix (is that even proper slang?) or two at shows, and have amassed a nice collection of characters I like, including most of the Doom Patrol. Since we started talking about the role playing games with Gar, I think we'll start a Heroclix investigation with Salad Head, from the DC 75th Anniversary Heroclix set coming out that it includes a wide array of Gar.
