Doctor Neo Cortex is the main antagonist. Cortex is depicted as a mad scientist who seeks to achieve world domination as an act of vengeance for the ridicule he has suffered in the past. He is aided by the wicked Tiki mask Uka Uka, who gives him advice on how to achieve this goal. Under his guidance, Doctor Cortex mutated the local animals into his soldiers, eventually creating Crash Bandicoot, the titular character of the series, but soon rejects him as unworthy of being in his army and removes him from his castle. As Cortex's actions endanger the sanctity of the islands the games are set in, Cortex's plans for world domination are often hampered by Crash along with other characters. Crash's constant interference has made eliminating Crash one of Cortex's top priorities along with world domination. 

For Cortex, I need a voice that's similar to Lex Lang's performance
