Upchuck is the Omnitrix's DNA samples of the Perk and Murk races of Gourmand from the destroyed planet Peptos XI and currently Peptos XII.


Ben as Perk Upchuck

Perk Upchuck has green skin, six sprout-like growths on the back of his head, a dark-green patch of skin on his head, light-green skin on his face and belly and a crooked teeth overbite. He has whisker like lines on his face, and a green tail.

In the original series, Perk Upchuck had white eyes and wore a black open-front suit with white over-sleeves and white bands around his legs and white padding under his three-toed feet. He wore the original Omnitrix symbol on his left hand.

In Omniverse, 16-year-old Perk Upchuck does not wear clothes and his eyes are recolored green. He wears the Omnitrix on his stomach.

11-year-old Perk Upchuck looks almost the same as the original series, but his eyes and original Omnitrix symbol are recolored green and he now has bare feet with short claws.

Ben as Murk Upchuck

Murk Upchuck has swampy-green skin, a tanned stomach and muzzles, black sprouts and black-green spots on his tail, limbs, and back. His eyes are sharp and green, he has whisker-like lines, his teeth are more aligned with visibly sharp canine teeth and his tail is short and straightened, as opposed to Perk Upchuck's curled tail.

In Heroes United, Murk Upchuck's black stripes on his face were longer, reaching his mouth, and he only had two lines instead of three. His claws were attached to his hands through finger stubs.

In Omniverse, Murk Upchuck resembles his previous design, except that his claws are longer and bigger, his sprouts are brighter, and he has less spots on his body. He now has only two teeth in the shape of an underbite, and the markings on his face are thinner and contained by the face, no longer spanning the head. Murk Upchuck wears the original Omnitrix/Ultimatrix/Omnitrix symbol on his stomach.

Powers and Abilities

  • Stretchable Tongues: Depending on his race, Upchuck has either one or four prehensile tongues which can be used to grab things from a distance.
  • Solid Matter Ingestion: Upchuck's stomach allows him to consume practically anything; be it a tire, droid or missile launcher. Upchuck has even consumed energy blasts and a giant Mr. Smoothy.
    • Explosive Vomit: After consuming something, Upchuck spews out explosive vomit which can be used as an explosive projectile.
    • Acid Spit: Upchuck is capable of generating acidic saliva.
    • Slime Spit: Upchuck is capable of generating slime which is able to thaw him out of a block of ice.
  • Enhanced Durability: Upchuck is capable of withstanding an attack that sent him through a concrete wall.
  • Enhanced Agility: Upchuck is capable of dodging energy blasts.
  • Enhanced Speed: Upchuck was able to spin around so fast he created a vortex.


Both Upchucks have a limit to how many big objects they can swallow at once. They also become slow and excessively when they eat a lot of things. Otherwise, they are somewhat quick, considering their small size.

If either Upchuck does not spit out something they eat, they will get very fat and rendered immobile until they spit it out.

There is a limit to the kinds of energy either Upchuck can ingest, as the energy beams of an Evolved Galvan made them inflate into a ball.

Either Upchuck can be temporarily immobilized by a Necrofriggian's ice breath until they thaw themselves free using their slime.

Despite being able to eat a Celestialsapien, neither Upchuck can gain the latter's powers in any form or way.



  • Upchuck does not have a natural predator because his species is at the top of the food chain.
