Zavok is a red Zeti with a very stocky build. The majority of his upper body is pure red. He has five-fingered hands that end with sharp cyan-colored nails. His lower jaw sticks out, showing a row of spiked fangs. The upper half of his head is black save for red markings around his eyes, which are purple with yellow sclera. Zavok has what appears to be a relatively thick cyan-colored unibrow that forms a vaguely V-shaped crest. Sticking out from the sides of his head, Zavok has two vicious curved horns that are striped in varying shades of dark gray. Zavok appears to be bald, sans for a cyan ponytail sticking out from the back of his head. Zavok has two rows of sharp black spikes sticking out of his shoulders. His only attire seems to be a pair of black bracelets with gray spikes jutting out.
At some point in the past, a man named Dr. Eggman invaded the Lost Hex with his many Badniks. He enslaved Zavok and the other members of the Deadly Six with an ancient relic. Soon, he was freed unwillingly by Sonic the Hedgehog and thus exacted his revenge with his team by taking control of Eggman's Badniks with their electromagnetic powers. The Deadly Six were later stopped by Sonic, relinquishing their control of the Badniks. Following their defeat, the Deadly Six took over one of Eggman's bases he left in Lava Mountain Zone and remade it in their image, calling it Zeti Castle.
The Last Minute
One day at Zeti Castle, Zor reported to Zavok how the Eggnet was in chaos due to Dr. Eggman's doings on the world down below. The two were soon visited by a person named Dr. Starline. He introduced himself as an assistant to Eggman and requested that the Deadly Six help them with a current crisis that they were in. Starline let Zavok know that Eggman did not actually know he was on the Lost Hex but told him that working with the Eggman Empire once again would give the Deadly Six an opportunity to make amends with the doctor, command incredible power and destroy Sonic. Hearing all of this made Zavok accept Starline's proposal. After the doctor left however, Zavok confided in Zor how Starline made a mistake and that they would capitalize on it. Zavok soon assembled the entire team to inform them of Starline's offer and how they would immediately betray him, though they all seemed to barely listen to him. Zeena initially showed dislike for the idea of going back to Eggman as it could very well be a trap. Zavok immediately snapped at this, saying that since they underestimated the doctor the first time, they were now well prepared. Zavok planned for them to punish Eggman for their humiliation, destroy Sonic for defeating them, and then destroy their world below.
Some time later, Master Zik praised Zavok for his initiative on letting the Deadly Six bide their time to let their anger and hatred fester but warned that their vengeance against Sonic and Eggman must be exact. Soon, the duo were met by Starline, who told them that today's events cemented the fact that the team's help was needed. To prove that they could exert their will over machines, Zavok took control of a Moto Bug and has it drive around. Starline then told that after he made last minute preparations on his end, he would come back for the Deadly Six. After Starline left, Zik gloated as to how he was naïve and they would swiftly betray him. Zavok declared that they will use the Zombots to destroy Eggman, Sonic and the entire world below for merciless vengeance and absolute victory. Soon enough, the Deadly Six were brought onboard Eggman's Faceship via Starline's Warp Topaz.
All or Nothing
Upon seeing the Deadly Six, Eggman immediately sent Metal Sonic to attack them. Zavok swiftly used his electromagnetism to control the robot and tauntingly reminded Eggman how they were able to control robots. Following this, Starline presented the Cacophonous Conch and blew into it to try and control the Zeti. Once Zazz saw that Starline had left an opening after using the conch, he headbutted him which allowed Zeena to take the conch and give it to Zavok. With Eggman and Starline defenseless, Zavok commanded Metal Sonic to attack them; however, Starline hurriedly opened a Warp Portal that transported him, Eggman and Metal Sonic away. Noting that they were now left with the Faceship, the means to create Eggman's Metal Virus, and the fabled Chaos Emeralds, Zavok decided to remove an Emerald and place it on his chest to empower himself with it. He was met with praise for his intuition by Orbot, who claimed that he and Cubot were too spineless to turn on the Deadly Six; after Zavok commanded that the robot take them to the largest known pockets of survivors, Orbot complied but not before telling them that he will log their orders to keep them well coordinated. With this, Zavok plotted out the Deadly Six's new plan; each of them would take one Chaos Emerald to be empowered by so that they can control thousands of Zombots around the world instead of random, shambling masses. He planed to bring utter devastation to the world that Eggman and Sonic had been fighting over for so long; once every living thing had been infected and neither party had anywhere else left to run, they would give them mercy of a slow end by the Zombots themselves. The Zeti set out into the world controlling many Zombot hordes, as well as terrorizing several uninfected citizens. While Zavok stayed in the Faceship, he stated to Master Zik that he was not resting on his laurels and would see to it that they infect everything from coast to coast by that night, and by tomorrow, the world.
Zavok continued to question Orbot and Cubot about Eggman's whereabouts and had them search all of his bases, no matter how remote or obscure. They soon came across Angel Island, which Orbot began to lengthily explain about. Cubot interrupted, saying that there was an alert in the Metal Virus factory. While running down to the factory, Zavok believed that this may be Sonic sabotaging his plans and plotted to rip him in half.
Zavok is a strong-minded individual who cares only for power and his team, the Deadly Six, though he can snap at them if they step out of line. He is a malicious character, yet has a calm demeanor with little patience for time wasting. He despises those who pose a threat to him and sees himself as a figure above all others.  Zavok is also a very vengeful person and has no qualms in enslaving or destroying an entire world just to take revenge on someone that upset them, as evidenced when he and the other members of the Deadly Six tried to turn every individual on Sonic's world into Zombots with the Metal Virus just because they despised Dr. Eggman and Sonic. Zavok is also quite a tactical thinker and knows to always seize opportunities when they present themselves.
