Zazz

Zazz is one of the main antagonists in Sonic Lost World. He is a Zeti, and is one of the members of a group known as the Deadly Six, who antagonizes Sonic the Hedgehog in this game. 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. But after Sonic arrived and got rid of the Cacophonic Conch, Zazz and the other Deadly Six members rebelled against Eggman, and took control of his robotic forces.
