Other times, Cortex himself does the brainwashing. Crunch was originally conceived with brainwashing intact so that he would obey Cortex faithfully.
Crunch has been brainwashed on three separate occasions. The first time was in Wrath of Cortex, where he was brainwashed by Cortex to obey him and the Elementals faithfully (However, this occasion may not have been the result of brainwashing, but the mere fact that Cortex created Crunch.). He eventually breaks free and befriends Crash.
The third time occurs in Crash: Mind Over Mutant, where he is brainwashed by N. Brio and the "NV," a do-anything personal digital assistant. He is outfitted with a helmet with goggles, and becomes ferocious and giant. He is broken free once again after Crash defeats him.
Coco has been brainwashed three separate times. The first time happens in Crash Bandicoot 2: N-Tranced. She is brainwashed by N. Trance to kill Crash, and the two engage in battle. She escapes his control after Crash defeats her.
The third time happens in Crash: Mind Over Mutant, where she is brainwashed by N. Brio and the "NV," a do-anything personal digital assistant. Her body mutates into a scary, monstrous creature. She is later defeated and freed by Crash.
Polar and PuraEdit
Polar and Pura are brainwashed by N. Trance to race for his team in Crash Nitro Kart. They are both brainwashed by N. Trance's helmets, and stay under his control for the entire circuit. Neither change in personality or appearance while they are brainwashed.
Polar is shown to have been freed in Team Bandicoot's ending, relaxing on the beach helmet-less with Crash, Coco, and Crunch. Being the other ally of Crash that was brainwashed, it can be assumed that Pura was freed as well.
Dingodile is brainwashed by N. Trance to race for his team in Crash Nitro Kart. He wears one of N. Trance's helmets, and stays brainwashed for the entirety of the circuit. His eyes turn green (the same color as N. Trance's eyes) after being brainwashed and look in opposite directions, and he appears extremely brain dead. This hints that Dingodile recieved the much more powerful brainwashing than Polar and Pura, and was the slave that N. Trance was most fond of.
In Team Bandicoot's ending, Polar is shown to have been freed from N. Trance's hypnosis. However, in Team Cortex's ending, Cortex, Tiny, and N. Gin are accidentally teleported to Terra, leaving Dingodile, still brainwashed and under N. Trance's powerful mind control, stuck in the coliseum with N. Trance and Emperor Velo. It is unknown how Dingodile escaped his brainwashing, or even if he did at all.
