Holly Wood - El Gado's palette swap. He sported a goatee, wore a beige suit and a bandanna on his head. In some occasions, he came dressed in red and brandishing molotov cocktails, which he threw at the heroes just before leaving. This version was much weaker than usual, and required only one hit to be killed off.

Slash - Axl's palette swap. He had short, curly, dark hair.

Two P sported an orange mohawk, wore shades, dressed in orange and blue and had a dragon symbol on his back, while J had his blond hair upright, dressed in yellow and dark blue and had an atomic biohazard symbol on his back. In the game, they tend to strike when the player has their back turned on one of them.
