Didn't look into them, no. Most I've seen is golden showers.
Well I'm less concerned about the fans. I can't trust the developers to include customs that have a right way to be used. Many of the items they added in Tekken 7 are just random objects sitting on the character's head. A Jenga stack, a miniature SUV, a desk fan. It's like no one has any creative vision as to what the characters might actually wear, so they just throw random junk in random places.
