Cortex's Hoverboard

Cortex's Hoverboard is a hoverboard seldomly used and owned by Cortex. Cortex uses this hoverboard when battling Crash, when he uses his laser gun to attack. So far, it has been destroyed in every one of it's appearances.

Crash Bandicoot
Cortex uses his hoverboard when battling Crash in his final boss fight, where he rides it out of the castle to confront Crash on the blimp. The hoverboard is destroyed at the end of the boss fight, blasting Cortex off down to the island.

Crash Bandicoot 2: Cortex Strikes Back
The hoverboard can be briefly seen when Cortex is falling in the intro, where it explodes behind him.

Crash Bandicoot 3: Warped
Cortex uses his hoverboard when fighting Crash in the last boss, where it appears to have to have two copies.

Crash Twinsanity
The hoverboard reappears with a new model, where Cortex uses it in his boss fight, where it has three copies. When a missile from Mecha-Bandicoot accidentally hits the hoverboard, it goes out of control and flies into a mine with Crash and Cortex, where it is last seen jammed into the ground.

Trivia

 * In Crash 1, when Cortex is defeated, hi Hoverboard explodes and he falls. But in the intro of Crash 2, he is seen falling with it before it explodes.
