- "Can't let you do that, Star Fox!"
- ―Wolf O'Donnell
Wolf had been a bounty hunter who was hired by Darth Animal to hunt down and kill members of The Super Smash Brotherhood. Wolf's main enemies were member Fox and his sidekick Falco. Before being hired by Animal, Wolf helped Darth Pillsbury and Gunter try to assassin Darth Elmo. Wolf had dueled with Animal later and nearly killed the Madclaw! if only Animal didn't use Force disco on him.
Wolf had snuck aboard Fox's ship, the Lylat Cruise. Fox and Falco were rushing to Yoshi's Island to pick up Yoshi and the traitorous Samus. Darth Animal ordered Wolf to kill Fox and Falco, then trick Yoshi to board the ship then kill him, capture Samus, freeze her in Carbonite, destroy the Lylat Cruise, then kill the other brotherhood members, and finally kill leaders Mario and Darth Squidward. However, Fox and Falco caught Wolf trying to blow up the fuel tanks. Falco threw a bomb on Wolf, before being shot by Wolf. Wolf died in the explosion. Star Wolf had been destroyed.
Darth Animal had learned of the death of his personal guard. He then met up with Floyd Pepper who became his trainer.
