Upchuck is the Omnitrix's DNA sample of a Perk Gourmand from the destroyed planet Peptos XI and currently Peptos XII.


Perk Upchuck has green skin, six sprout-like growths on the back of 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.

He wears a black, green and white open-front suit with white over-sleeves and white bands around his legs. The Omnitrix symbol is located on his left arm.

Powers and Abilities

Upchuck has four very strong, adhesive tongues 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.

Perk Upchuck can make his "loogies" curve like a boomerang, shuriken, or frisbee. He can also fire powerful streams of his explosive vomit like an energy beam by building up digested matter and releasing it all at once.

Perk Upchuck is able to take a surprising amount of punishment for a creature of his size, taking the force of a moving car impact, as well as surviving after being thrown through a wall.

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.


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.

Perk Upchuck cannot consume Earth/human food. 

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