Dingodile is a genetically enhanced combination between a dingo and a crocodile as he has a crocodile's tail and a dingo's body with an Australian accent.
He makes his first appearance in Crash Bandicoot 3: Warped, after which he makes regular appearances in the series up until Twinsanity.
His latest appearance is in Crash Bandicoot Nitro Kart 2.
Dingodile is often equipped with a flamethrower, which is fuelled by a large gas tank worn on his back. The flamethrower is occasionally traded for a water gun. He is also known to attack with his tail.
It is generally assumed that Dingodile was created by Doctor Neo Cortex, but some sources claim Doctor Nitrus Brio to be his real creator.
This may be one of the reasons of why Dingodile has no trouble betraying Cortex from time to time. Links Crash Bandicoot Wiki Crash Mania
