Mecha-Bandicoot

Mecha-Bandicoot is a Bandicoot-like Mech that first appeared in Crash Twinsanity as a first boss alongside Dr. Neo Cortex and N.Gin, whom the latter was using him to destroy Crash Bandicoot with missiles and chainsaws, but ending with Crash defeating Mecha-Bandicoot, making it throw a temper tantrum and stomp a hole in the platform it was on, leaving it crashed at the bottom of a cave. Later, in the Evil Twins' boss fight, Crash is controlling him in order to defeat the Evil Twins. It's armed with a missile launcher, a chainsaw and a plasma cannon.
