Remember Sandy Collora, the guy who created the Dead End Predators? He has a Kickstarter for some of his original designs.
The Tiburonera Tribe is apparently based on a short film he also funded through Kickstarter, and are perfect for putting with 6" (Hasbro, Mattel) or 7" (Four Horsemen, NECA) figures. Collora had an earlier campaign a few years ago, to create 3¾" retro-styled figures (sadly, we never heard about that one), but these are the big, modern kind of figures you see on the shelves today. What collection couldn't use some more cool monsters in it?
