Zavok

Zavok is one of the primary antagonists in Sonic Lost World. He is a Zeti and the leader of the Deadly Six. When Dr. Eggman came to the Lost Hex, Zavok and the other members of the Deadly Six were forced into serving the doctor due to the effects of the Cacophonic Conch. After Sonic the Hedgehog arrived and got rid of the conch, Zavok and the others rebelled against Eggman and took control of his forces. Zavok then enacted his plan to achieve world domination by using Eggman's Extractor to make himself and the other Deadly Six stronger, while destroying Earth, but was ultimately defeated by Sonic.
