Upchuck

He is one of the original aliens from Ben10

Powers
Being a Gourmand, 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 can also stretch, allowing him to swallow and digest objects fairly larger than itself. Upchuck possesses several acid-filled stomachs that dissolve almost all forms of matter, except ironically, ordinary human food and other organic matter. The items ingested are converted into explosive balls of liquids that can be expelled at will with great accuracy, he can also make them curve, like a boomerang, shuriken, or frisbee. This ability was demonstrated in Ben 10 Secret of the omnitrix. Upchuck also seems to be able to take a surprising amount of punishment for a creature of its size, able to take the brunt force of a moving car impact as well as surviving after being thrown through a wall.

In Alien Force, Upchuck can now eat food, Unlike in Ben 10 when he couldn't.
