Arachnina

The Arachnina is Nina's mech suit, which is half-robot, half-spider. It has all the weapons in the Cortex family arsenal, in particular a laser beam and a sawblade. When Nina fought Crash Bandicoot with this arachnid terror, Crash used the robot against her by jacking it, and destroying the Doominator. To jack it you have to jack a Battler or a Rhinoroller to jack the Scorporilla and then use the Scorporilla to jack the Arachnina.

Moves
Light Attack Spidey Combo: The Arachnina attacks with its blades.

Special Attack Robtomize : The Arachnina folds up into a faster, more spider-like form and unleashes a Laser Blast.

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

Arachnina is the biggest titan in the game, easily twice the size of Shellephant, Scorporilla or Yuktopus, previously the largest monsters in the game.
