Arachnina

The Arachnina is Nina's mech suit, which is half-robot, half-spider.And it has all the weapons in the Cortex family arsenal and more. It has many attacks, such as a laser beam and a sawblade. It contains everything in her arsenal, as well as some that were "borrowed" from Cortex. When Nina fought Crash Bandicoot with this arachnid terror, Crash used the robot against her by jacking it, and destroying the Doominator.

Whenever Crash "jacks" Arachnina, you see crash jumping on top of Nina and pushing her out of sight.
