Crash Bandicoot: The Wrath of Cortex
Under Cortex's command, Crunch was forced to battle Crash multiple times in the game, and each time he would use the powers of an evil Elemental mask to assist him. However, using the energy from Power Crystals, Aku Aku was able to seal away each Elemental mask and forced Crunch to seek the help of his creator. After the final boss battle, Crunch is accidentally freed from Cortex's mind control and has a change of heart, escaping with Crash from the villain's space station. Afterwards, Crunch thanks Crash and his allies for saving him.
Crunch made a brief appearance during the intro of the game's first boss fight. He is seen wearing an birthday hat and holding a cake.
Crash of the Titans
Crunch is seen hanging out with his friends in front of Crash's house when Cortex's airship appeared and kidnapped both Coco and Aku Aku. Cortex then fires a freeze ray which hits Crunch and freezes him from the neck down. Crunch then spent most of the game frozen in place until the ending when he finally breaks free after Cortex's Doominator robot collapses right beside him.
Crash: Mind over Mutant
Crunch became one of the unfortunate victims of the NV entertainment devices. Transforming him into an monsterish version of himself under the control of Dr. Neo Cortex and Dr. Nitrus Brio. When Crash and Aku Aku confronted N. Brio at the junkyard, the doctor orders Crunch to destroy them. But the heroes take control of Crunch and make him attack N. Brio instead. After N. Brio's defeat, Crash managed to pull off the NV device from Crunch's head which reverted him back to normal and restored his free will again.
