Zavok

Zavok is a Zeti and the leader of the Deadly Six, the main antagonists of Sonic Lost World. When Dr. Eggman came to the Lost Hex, Zavok and the other members of the Deadly Six were forced into serving him, due to the effects of his Cacophonic Conch, though after Sonic rashly got rid of the conch, the Deadly Six rebelled and took control of Eggman's forces.

Zavok makes an appearance as a playable character in Mario & Sonic at the Rio 2016 Olympic Games in the Boxing Event. This marks his first playable appearance.
