Uka Uka

Uka Uka is the second main antagonist in the Crash Bandicoot series and a voodoo mask spirit who is the evil counterpart of Aku Aku, whom he is the twin brother of. He is ultimately the driving force behind a massive evil plan, which he often uses to work with Doctor Neo Cortex and is frequently upset with Cortex for his failures. Uka Uka has a short temper and, as a result, is very impatient and he blames Cortex every time he fails.
