Polar

Polar is a polar bear from the Crash Bandicoot franchise. He's a friend/pet of Crash. He first appeared in Crash Bandicoot 2: Cortex Strikes Back. Here, Crash rode him through some of the game's levels to collect Power Crystals and escape attacks from larger, more menacing polar bears. He returned in Crash Team Racing, this time being playable on his own. He joined Crash's team to help defeat Nitros Oxide. In Crash Nitro Kart, he's once again playable, however, he's no longer on Crash's team. He was kidnapped and brainwashed by N. Trance, who hypnotized him into racing on his team. However, Team Bandicoot rescues him at the end of the story, and returns home with him.

Trivia

 * Polar made a cameo appearance in Crash Twinsanity as one of the villains wanting to have their revenge on Crash. However, this is merely a joke, and he's not actually a villain.
