The Impact Miniature kickstarter, who's goal is to create a whole bunch of chibi style miniatures for both collectors and traditional games players, has released a bunch of new images and videos showing off their ideas for pony models. We even got a Cthulu pony, complete with tentacles and bat wings!
Have some videos:
It looks like most of them can be modified as you see fit, via replaceable parts. They released a spreadsheet with all of the possible combinations. If you want to support the project, hit up their kickstarter here!
