Nacho Cheese is Pizza Steve's father and the main antagonist of Nacho Cheese. He is voiced by Henry Winkler.
He is a triangular tortilla chip coated with golden orange cheese dust. He also wears a pair of sunglasses on his face and also has his arms and legs made out of cheese.
More boastful and arrogant than Pizza Steve could ever be, he is incredibly selfish and self centered. He needs literally everything to be about him and does not care about anything or anyone other than himself. He's so self centered that he doesn't even care about his own son and would gladly throw him under the bus if it means he gets extra attention.
- He has similar characteristics to another character Henry Winkler portrayed, Arthur "Fonzie" Fonzarelli from Happy Days.
