He' s Crash Bandicoot's evil 10th Dimensional counterpart and his neutral rival. He has sharp teeth, long claws, green eyes with red pupils, spines sticking out of his back, and his feet come out of his shoes somewhat. He has a much darker fur color than Crash's, his arms are also much longer, and his hair is less spiky than Crash's. While Crash uses easy simple attacks, Evil Crash has erratic and dysfunctional ways of attacking. He's impulsive and aggressive, and is shown to be somewhat immune to objects that would cause harm to Crash, such as Nitros, TNTs, and even enemies. He is much stronger than Crash. Evil Crash is also a carnivore and lives on a steady diet of meat. This might explain why he captured Nina and chased Cortex. Evil Crash hardly looks like his realistic counterpart, but slightly shares his personality.
He may be also the brother of Evil Coco.
He is first seen in the first cutscene of Twinsanity Island where Cortex thinks he's hugging Crash, noting "Your fur is so soft, and warm." Crash and Nina back away, then Cortex looks over at Evil Crash, who then hops over Cortex and kidnaps Nina, leading to the next level where Crash must pursue Evil Crash. After finding Evil Crash with Nina tied in ropes, Cortex bravely says "Let her go, take me instead!" Then ends up in Evil Crash chasing him. After the chase is over, Crash can continue the next level. At the end of the game, he ate the Evil Twins when they fled into his house. He is seen in a background picture in the credits in a huge rollerbrawl with the other characters of the game.
Crash Tag Team Racing
Evil Crash appears as a skin in CTTR, sold in Mystery Island for 2500 coins and going by the name of Nega Crash, which has a much different look from the real Evil Crash. Nega Crash has actual fingerless gloves, has no hair on his back, has a foot hole on one of his shoes, and has spines on his back. He was originally going to appear as a racer.
Crash Boom Bang
Evil Crash was going to make a appearance in Crash Boom Bang but for unknown reasons he was cut from game. However he does make a cameo in one of the minigames.
