A handful of pun-based skin ideas. Some I would actually want to see in the game, some... not so much.

RagnarOS (computer-based)

Lt. Murktaugh (he's too young for this shit)

Azmodank or Illidank (with a Pepe face)

Xul'jin

A Li Li skin for Li-Ming and a Li-Ming skin for Li Li

Bitches (the world's ugliest pimp)

Nazeebro (wearing a t-shirt, jeans, and a beer helmet)
