Burgot [Urgot skin idea]
His body is now in a burger costume and he has one of those hats people wear at fast food places. He wears a apron on his lower body as well. His cannon hand now has french fries in it and his blade is a burger dispenser(Or Spatula). On his back instead of the metal rods he would have Deep fryers filled with oil.
His Q would be a flying burger while his AA's are french fries. His Q could also shoot Spatulas instead of burgers.
His W wouldn't change much maybe make it look smoother, or it could be a burger bun shield
His E would be scolding fryer oil (The oil where french fries are "cooked")
And for his ultimate he could scream "ORDER UP"
