Apo-Apo

Apo-Apo is a mask similar to Aku Aku and Uka Uka, though it is unknown if he is a reincarnated spirit like them. He was introduced in Crash Team Racing: Nitro-Fueled as an invincibility mask item as part of the Rustland Grand Prix. He protects those racing on the Megamix Mania track as well as racers wearing Rustland themed skins. He will also appear during the podium animations for characters wearing Rustland skins.

Appearance
Apo-Apo is a brown wooden mask with yellow eyes and metal armor that features nine spikes, two on each side and five at the top along with metal teeth, and three green feathers on each side of his face. There is also what appears to be spots of rust on his armor.

Trivia

 * His design is essentially an amalgam of Aku Aku and Uka Uka in their Titans designs.
 * "Apo" derives from the word apocalypse, of which the Rustland Grand Prix he was introduced in is based on.
