Uka Uka

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