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—however, after Sonic got rid of the conch, the Deadly Six rebelled and took control of Eggman's forces.

In the 3DS version, Zavok appears during the sixth day of Sonic's Story in Road to Rio mode. If the player talks to him, he challenges them to a match of Boxing Plus. If the player accepts and wins, Zavok is unlocked as a playable character in Boxing and Boxing Plus in other modes.

In the Wii U version, Zavok has a high power stat, fairly low speed, and middling technique. In this version, there is a chance of Zavok appearing on Copacabana Beach during the Boxing tournament. If he is talked to, his flag is earned. Additionally, he can appear after said tournament is won and challenge the player to a Boxing match - if the player defeats him, he is unlocked as playable in Boxing.

Profile
''Zavok is the strongest of the sinister Zeti and the leader of the Deadly Six. As the last disciple of Master Zik, he's a certified force to be reckoned with. Along with his formidable physical prowess, a calm demeanor and penchant for quick-thinking makes his well-suited to leadership. His greatest joy is in improving his skills, which makes the straight-forward competitive nature of the Olympic Games quite appealing.''

Profile
''Smart and cool under fire, Zavok's power recognized by everyone, even his mentor. The other Deadly Six have a lot of respect for Zavok.''
