Rocky Balboa is a fictional professional boxer from the Rocky film series.
Rocky appears in the arcade game Rocky III vs. Clara Peller, found at Captain Blip's Zapateria. Player 1 is Rocky, while player 2 is Clara Peller. The two characters move back and forth inside a boxing ring while continuously spouting the same bits of dialogue, with Rocky saying "You ain't so bad," and Clara Peller asking "Where's the beef?"
He is also one of the many people on "Ned's List of Laudable Lefties".
