Zazz

Zazz is a Zeti and member of the Deadly Six, the main antagonists of Sonic Lost World. When Dr. Eggman came to the Lost Hex, Zazz 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.

Profile
''The wild and crazy member of Dr. Eggman's Deadly Six, Zazz is every bit the metalhead he looks like and his unruly and unpredictable personality makes him destructive even by Deadly Six standards. He hates boredom above all else, and will fly into a rage when held back from a fight. His competitive style is a bit more chaotic than is usually seen in the Olympic Games.''
