Events in Big Willy Unleashed!Edit
Kluckin serves as the primary antagonist after killing off Patty Wurst in Harbor City. After the events in Harbor City, the duo travel to Fairfield in aid to find where Kluckin hiding. They fail but they did destroy a group allied to him. Pox brings Crypto to Fantasy Atoll, an island located near Malaysia, as a tactic to beat Colonel Kluckin. After killing Mr. Pork they discover where Kluckin's hiding: Vietmahl.
As they land, they discover that the area is entrenched in war. After knocking out Kluckin's base's defenses, Crypto and Pox are kidnapped by the traitorous Trahn and Kluckin and he reveals his plan: he takes the dead bodies from the Vietmahlese War and others in South East Asia and turns them into meat for his restaurant, a similar plan used by Pox for his restaurants.
Soon, Crypto faces his nemesis in Vietmahl in a mechanical version of a rain forest god and subsequently, he is killed as Crypto (in his Big Willy robot) managed to destroy his robot after the intense battle.
He only appears in Destroy All Humans! Big Willy Unleashed.
