Polar

Polar is a polar bear from the Crash Bandicoot series, who debuted in Crash Bandicoot 2: Cortex Strikes Back.

How to Abuse a bear
He first appears in the eighth level (Bear It) of Cortex Strikes Back then later in Level 13 (Bear Down), the last part of level 15 (Unbearable) and the hidden level 26 (Totally Bear). In these levels, Crash will ride him. He is also present in the second Warp Room, near the entrance to Level 8. If the player jumps on him several times, he/she will obtain many extra lives. It is likely Crash took him home.

Polar is on the good side in the Crash Universe, except in Crash Twinsanity, when he is pictured as being one of Crash's enemies, and appeared alongside some of Crash's primary enemies upon being introduced by Dr. Neo Cortex. (possibly to get revenge on Crash for what had happened in his debut title) In the rest of the game series, he is kind and loving. He is one of Crash Bandicoot's buddies and his animal guardian.

Cameo
He is also seen in the intro of warped next to Crash.

On Your Marks!
In Crash Team Racing, when Nitros Oxide attacked Earth, threatening to turn it into a parking lot, Polar stopped his dream of being a literature genius (which he was not accomplishing by reading his books upside-down), and decided to race against the villainous. Polar is a playable character in his Kart. His home track is Polar Pass. His Kart handled tight corners, much like Pura.

In other Games
Crash also rides him in Crash Bandicoot: The Huge Adventure and Crash Bandicoot Purple.

Hypnotism
Later, in Crash Nitro Kart, Polar was brainwashed by N. Trance .He was on the alien racing team. However, in the ending, he hangs with Crash again. He drives a green kart in this game.

Evil?
In Crash Twinsanity, He seems to be mad at Crash for some reason. He is at Cortex's gathering holding a baseball bat to hit him with. This could be because of Crash jumpng on him in Crash 2, or N Trance brainwashed him again.

Two feet
Polar might be able to stand on 2 legs now, since he does in Crash Boom Bang! and Twinsanity.

Polar is also an Ice Cream tester as revealed in the epilouge of CTR.
