I never noticed it till now when a parent was outraged by her 8-years old son who was playing the Pokken game. It's like hardly noticeable in the DS as it is spikey and you can barely see it. Though I have to admit, the Pokken game did design it poorly in the 3D model.
I understand they're just simply feathers sticking out, but dang, why did they have to have the feathers stick out right there, and for Pokken to make it so round? xD
I always thought he had a lower body similar to Erza's "no armor" pants. I never realized there were feathers sticking out of his crotch.
