Murk Upchuck is the Omnitrix's DNA sample of a Murk Gourmand from the destroyed planet Peptos XI and currently Peptos XII.
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 yellow, he has whisker-like lines and his teeth are more aligned with visibly sharp canine teeth
He wears a black, green and white suit with his stomach appearing. The Omnitrix symbol is located on his upper left arm.
Powers and Abilities
Upchuck has one, adhesive tongue that can stretch to great lengths, allowing him to latch onto large objects and reel them in with relative ease.
Upchuck's mouth can stretch, allowing him to swallow objects larger than himself. He is connected to other Gourmands with a trans-space bladder dimension where they store all the "food" they eat. He can sense any danger to his people through his stomach.
By breathing air out of his mouth, Upchuck is able to fly and even survive in the vacuum of space.
The items ingested by Upchuck are converted into explosive balls of liquids that can be expelled with great accuracy. The explosive power of these "loogies" depends on the chemical composition and overall size of what Upchuck ate to create them.
Upchuck can eat and spit out energy, such as lasers, in the same way they eat and spit out acid matter.
Murk Upchuck can spit out slime, which can be slippery and is capable of melting ice.
Murk Upchuck can carry heavy objects in his stomach, such as the Alpha Nanite's container, and release them without having to turn them into a "loogie".
Although Upchuck hasn't trained himself to do so, he can eat the Ascalon and even a Celestialsapien, who would either be digested or spat back out.
Unlike Perk Upchuck, Murk Upchuck can ingest human/Earth food.
Upchuck has a limit to how many big objects he can swallow at once.
Upchuck is slow when he eats a lot of things and become excessively fat. Otherwise, he is somewhat quick, considering his small size.
If Upchuck does not spit out something he eats, he will get very fat and rendered immobile until he spits it out.
There is a limit to what Upchuck can ingest, as the energy beams of an Evolved Galvan made Perk Upchuck inflate into a ball.
