Zazz is an antagonist in the Sonic the Hedgehog series. He is a Zeti and a member of the Deadly Six. When Dr. Eggman came to the Lost Hex, Zazz 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, Zazz and the others rebelled against Eggman and took control of his forces. Afterwards, Zazz followed Zavok's plans to make him and the other Deadly Six stronger by using Eggman's Extractor, while destroying Earth, but was ultimately defeated by Sonic.
Many years prior to Sonic Lost World, Zazz was brought into the Deadly Six when Master Zik formed the group.
In Sonic Lost World, Zazz and the Deadly Six met Dr. Eggman, who used a Cacophonic Conch to enslave them. Zazz then begrudgingly helped Eggman in his scheme for world domination by capturing Animals for an army of Badniks. When Zazz joined Eggman and the Deadly Six for a Badnik-making lesson where Eggman told how they would help him beat Sonic the Hedgehog, Zazz left upon Zavok's permission to fight Sonic himself, only to lose to the hedgehog.
While in Windy Hill, Zazz and his team came across Sonic. On Eggman's orders, Zazz confronted Sonic while Eggman and his fellow Zeti left, only to be beaten again. Resuming the Animal hunt, Zazz would be punished by Eggman with the Cacophonic Conch when Zavok spoke against Eggman's criticism of their efforts. Zazz and the Deadly Six later endured further scolding for their failures by Eggman with the Cacophonic Conch when Sonic appeared and knocked the conch away. Now free, Zazz and his team took control of Eggman's Badniks and had them attack everyone at the site, with Zazz joining an attack on Eggman, before Orbot, Cubot, Eggman, Sonic and Tails chose to flee.
Having regained their freedom, the Deadly Six took control of Eggman's operations on the Lost Hex. While Sonic still opposed them though, Zazz was involuntarily used by Master Zik to demonstrate his physical prowess when he went after Sonic. Zazz subsequently went along with Zavok's plan to destroy the Earth with Eggman's Extractor and use the energies it harvested to make the Deadly Six stronger, thus getting their revenge at Eggman. Joining Zavok when he contacted Sonic's group to discourage them, Zazz taunted them with their impending deaths before Eggman cut them out.
As the Deadly Six plotted to turn Sonic into their robotic slave, Zazz helped set a trap up for Sonic, only to find Tails caught in it when it returned. As Zor then arrived to announce the failed capture of Sonic, Zazz scowled in response. Using their Extractor-enhanced strength, Zazz and Zomom would later ambush Sonic and his allies, knocking everyone except Sonic into a lava pit. Zazz subsequently teamed up with Zomom and Master Zik to finish Sonic off for revenge, only to be beaten for good. What happened to Zazz afterward is unclear.
And he is reprised by Robbie Rist in the English dub and Yutaka Aoyama in the Japanese dub.
