I've recently invested in more Heroclix to chop up and turn into new characters, plus various Copplestone/em4 miniatures to represent Police, Henchmen and street-level Vigilantes. So far I have Mime and Red Death (the Batman-esque supervillain who influences most of the schemes of the other villains) complete and a bunch more on the painting table.
Comments? Suggestions? I love how cheap this project is, with only two or three miniatures needed for each faction (although I have got various different factions and henchmen-types planned).
