Upchuck

Upchuck
Upchuck (voiced by Dave Wittenberg) is a Gourmand (from the French word meaning glutton) from the planet Peptos XI (Peptos being the Greek word for 'cooked' or 'digested'[1]).[23] Upchuck has four strong, adhesive tongues that can stretch to great lengths, allowing Upchuck to latch onto large objects and reel them in with relative ease. Upchuck's mouth and stomach also stretch, allowing him to swallow and digest objects larger than himself.

As a Gourmand, Upchuck possesses several acid-filled stomachs that dissolve all forms of matter, except, ironically, ordinary human food. The items ingested are converted into explosive balls of liquids that can be expelled at will with great accuracy.[23] Upchuck also seems to be able to take a surprising amount of punishment for a creature of his size, able to take the brunt force of a moving car impact as well as survive being thrown through a wall.

Upchuck first appears in the episode "The Visitor", when an alien named Xylene enters a code into the Omnitrix, activating the form.
