Gordo the Gruesome is one of the Dome of Doom Champions. He is an ape-like creature that has a big mouth and a big temper.
Gordo is a large, obnoxious fighter, and the first fighter Jack fights in the Dome of Doom. He is implied to be the champion (or a high-ranking fighter) prior to being dethroned by Jack.
His tactics include intimidation by shouting insults and taunts at his opponent before fighting him, and fighting with his fists and feet. Once enraged, Gordo grows even more monstrous and gains long, sharp nails on his feet and hands.
