Crash Bandicoot: The Wrath of Cortex
Crunch was created by Cortex to kill Crash by using the Elementals. Using the Elemental's power, Crunch took on different forms to fight Crash but was eventually defeated each time. After the final battle, Crunch was free from Cortex's mind control and became good, escaping with Crash and thanking him and his allies for saving him.
Crash Bandicoot: N. Tranced
Crunch was captured along with Coco and Fake Crash by Dr. Nefarious Tropy and brainwashed by N. Trance to help the pair achieve world domination. Crunch was outfitted with a shield, gun and jetpack before facing off against Crash in an aerial battle. Crash managed to defeat Crunch and free him from mind control once again. Crunch would then aid Crash in foiling the villain's plans.
Crash: Mind Over Mutant
Crunch became one of the unfortunate victims of the NV entertainment devices. Transforming him into a monstrous 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.
- The original developers and creators of the Crash games from Naughty Dog had stated that Crunch did not fit the universe and style of the game for some reason.
- It is unknown why Crunch has a mechanical arm, but it seems the arm can modified to fire projectiles, as seen in Crash Bandicoot 2: N-Tranced and Crash: Mind Over Mutant.
- In concept art for Crash Twinsanity, there appears to be a little island with Crunch and Fake Crash being surrounded by sharks.
