Zomom's entire body is somewhat circular in shape, giving him a rather chubby appearance. His upper body is a vibrant orange-yellow color. His thick arms end with equally large five-fingered hands with yellow nails. His lower body is pure black, and Zomom's legs are so stubby to be nearly non-existent. His flat feet are each tipped with a pair of yellow claws, with a third on the heel. Zomom appears to have some sort of stubby tail.
Zomom has thick yellow lips and he appears to be missing some teeth and others seem chipped. Unlike the other Zeti however, Zomom's teeth are square in shape instead of sharp fangs. Zomom has small red eyes with yellow sclera, with black markings surrounding each eye. However, his eyes rarely both point in the same direction. Zomom is fully bald, unlike the other Zeti. On the top of his head Zomom appears to have four relatively short yet sharp horns, each one being striped black and red. On his wrists Zomom wears a pair of black bracelets with gray spikes.
At some point in the past, a man named Dr. Eggman invaded the Lost Hex with his many Badniks. He enslaved Zomom 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.
The Last Minute
Zavok later assembled the entire team to inform them of Dr. Starline's offer to help handle Dr. Eggman's crisis on the world below and how they would immediately betray him, though Zomom did not pay much attention to him while he ate his sandwich. 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. 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 Cacophonic 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. Zomom took the turquoise Chaos Emerald and set out to Vista View. There, after taking control over all of the Zombots, he forced the children of the village to provide him with food. When one child brought an unsatisfying portion for the Zeti, he commanded a few Zombots to come by and infect him; Zomom then declared that either the villagers feed him or else he would feed them to the Zombots.
Later, when Zomom was wolfing all the food down in a restaurant, he was confronted by Miles "Tails" Prower and Amy Rose. Zomom was able to recall Tails as one of Sonic's friends. In an attempt to trick the latter into handing over the Chaos Emerald he had, Tails and Amy "explained" to Zomom that they were entrusted by Zavok to escort his Emerald to him. Zomom refused, as this would mean losing control of the Zombots that kept bringing him food. Zomom then prepared to fight the two, as they had interrupted one of his many meals. Zomom chased Tails and Amy while trying to attack them, though he was temporarily stopped after he was hit in the face by Amy's hammer; the Zeti was then trying to eat Amy's hammer. While the owner tried to pull it out of his mouth, Tails attacked him as well, forcing him to spit it out. Enraged, Zomom declared that "he was gonna chew them real hard now before swallowing", but when Tails mentioned something about dropping his lunch box while he was chasing them, the Zeti turned back to go find it. After tearing through a couple of buildings, he realized that he had been tricked and returned while now feeling "hangry". He raised his hands and commanded the Zombots to attack Tails and Amy, forcing them to escape to higher grounds. As the two continued to evade the Zombots from above, Zomom called them annoying. He then burrowed under the ground, causing a mini earthquake to collapse the building Amy and Tails were on. Zomom followed them while burrowing underground towards the town gate. Just as he was underneath it, he popped out. This was revealed to be a trick; Amy and Tails slammed the gate shut onto his stomach, trapping him. As the duo expressed their victory to him, they took his Chaos Emerald and left. Zomom demanded them to give it back, as this would mean he could not control the Zombots anymore. He then became stunned upon seeing the Zombots surround him.
Out of the Blue
After Super Sonic and Super Silver had reversed the effects of the Metal Virus all around the world, the Zombots were no more and were cured. Once the villagers of Vista View found Zomom trapped underneath the gate, they assembled more items to place down on top of him so that he would not move. The Zeti still managed to grab the gate, push it upwards and free himself. Looking at the grooves made in his stomach, Zomom acknowledged himself looking like a waffle and demanded that the villagers bring him waffles.
Eventually, Zomom was caged by the residents of Vista View, who would only give him three meals a day, leaving him weak from hunger. While Zomom had to watch the inhabitants have a feast without him however, Zavok and Zazz showed up, who freed him and allowed him to take his anger out on the inhabitants. After then regrouping with the rest of the Deadly Six, Zomom joined his pack as they set out to attack the new Restoration HQ. Before that however, they attacked the inhabitants of Orchardville in order to confuse their enemies and leave the Restoration HQ vulnerable. Zomom and his pack hit Restoration HQ soon after. While there, they defeated the local guards and caused a lot of damage. Zomom in particular went the machine shop to look for potential victims, but Dr. Starline showed up and used his hypnosis tool to make him return to the rest of the Deadly Six without telling them of his presence. Zomom and the Deadly Six tried afterward to get into the control room, but then Sonic showed up to challenge them.
Zomom proceeded to participate in the fight with Sonic, during which he got shot by Whisper's Variable Wispon. Despite this, he eventually managed to grab Sonic. However, he was then neutralized by a Zeti Zapper that Tails put on him. Forced to surrender, Zomom and his pack were deported back to the Lost Hex in the Zeti Launcher by Sonic and Tails. Arriving in the Lava Mountain Zone, Zomom and his teammates then watched as the Zeti Launcher self-destructed and their Zeti Zappers deactivated. Zavok then consoled Zomom and the others by saying that they would not fall for such tricks anymore, and as the Zeti who has achieved more than all the others who came before them, they would learn from this experience and eventually enact their revenge with more brutality than ever.
Zomom's defining traits are his stupidity and gluttony; he is very gullible and can fall for the simplest of lies, and he has a boundless appetite. Favoring food over battle, he is willing to eat anything that looks remotely edible or comes into contact with his mouth, even weapons such as the Piko Piko Hammer. Even when he does not have immediate access to food, he will take note of shapes that resemble it, causing him to become even hungrier. Zomom is also quite short-tempered, showing no tolerance for people who interrupt his meals or fail to bring him enough food.
Like all of the other members of the Deadly Six, Zomom is malicious, enjoys violence, and does not care for the well-being of anyone other than his fellow Zeti. He 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 him or his pack, as evidenced when he and the other members of the Deadly Six tried to use the Metal Virus to turn every individual on Sonic's world into Zombots out of hatred for Dr. Eggman and Sonic. Zomom only finds true fear from his leader, Zavok.
Powers and abilities
Zomom is incredibly strong, able to smash buildings with the simple swing of an arm and incapacitate even Sonic with a single hug. He also has a high level of durability as demonstrated when he received a hit from Amy's hammer face-first and a laser shot shot from the Variable Wispon without sustaining any serious injuries. Zomom is also able to use his massive build to his advantage crashing down into the ground to create large tremors that are strong enough to destroy an entire building. In addition, Zomom is a very profound burrower; by putting his arms out to the sides and spinning around like a top, he is capable of digging through the ground at great speeds.
Like all other Zeti, Zomom's powers are greatly inhibited when the Cacophonic Conch is blown, which causes him great pain. His electromagnetic capabilities are as well hindered by EM shielding.
