>>5944590If you're into the poseable nature of Stikfas, Lego's Bionicle and Star Wars figure lines have a lot to offer. Their modular building system primarily uses ball joints, which does wonders for articulation.
The sets you see on the shelves have armor and weapons and stuff, but being Lego, it's easy to take the character flairs off and be left with a blank-slate poseable figure to do whatever you want with.
