I made characters called Sphere Strikers. They are characters heads, strictly round, and hold objects without hands. They can be anything, from ninjas to clones to superheroes.
I make comic books about them. I am working on Sphere Strikers Ninjago.
(For you Ninjago fans,there is a funny part when Samukai says his best men are searching for the Sword of Fire, and then Nuckal and his army turn out to be one of "his best men".)
What are your geometric defenders?
