One of the recent superhero miniature ranges I've been really excited about is the Pulp-City range from Pulp-Monsters.
Pulp City has a range of different models from homages to new and original characters and so far all of the figures I have gotten from them are outstandingly well sculpted and cast.
The 3 characters today are members of a super-team called "Heavy Metal" which relies on alot of technological heroes but also includes some aliens and a few others.
I'm finishing up a few more figures that have been 'mostly' finished over the next few days so you should be seeing a few more superheroes (and villains) around these parts.
Nuclear Jones, Iron Train & Androidia
