In the SNES version of Super Punch-Out!!, Gabby Jay is the weakest opponent that you face in the game. The story behind him is that he was born in France, and originally worked as a waiter in a cafe near the Eiffel Tower, soon he somehow felt the need to take up boxing. His only win was against Glass Joe according to the SNES Super Punch-Out!!'s instruction booklet (which earned him a diploma from the "Glass Joe School of Boxing"). Like Glass Joe, Gabby's signature move is the 'Taunt Punch', which he jumps away from his opponent, shouts "C'mon!" twice, jumps slowly toward his opponent and throws a punch. He will also shout "Yay!" sometimes which allows him to recover half of his health. Gabby Jay's offensive and defensive skills are also poor, which takes quite a while to throw any punch. He wears gray boxing gloves, and his palette swap is Bob Charlie. He will shout "Yay!" three times should he be able to win.
When Gabby Jay shouts "C'mon!!", hit him before he returns to the center.
When Gabby Jay moves to the left or right after his corner man tells him to stop attacking, hit him in the opposite direction to the direction he moves.
