In Omniverse, 16 year old Upchuck has two different looks, due to there being two types of Gourmand. Perk form resembles his Alien Force/Ultimate Alien design except that his claws are longer and bigger, his sprouts are brighter and he has less spots on his body. His Murk form closely resembles his 11 year old form without clothes.


11 year old Upchuck

11-year-old Ben as Upchuck in Omniverse is a Murk. He looks almost the same as the original series, but now has green eyes the Omnitrix symbol on his left hand is now green, and he doesn't have the padding on his feet.

Powers and Abilities

Upchuck has four very 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 himself. He can also spit his logies on the ground to fly.


Ben 10: Omniverse

  • In Store 23, Upchuck made his first cameo re-appearance. (Murk)
  •  In Tummy Trouble, Upchuck was used to settle peace negotiations for the Gourmands. (Both Perk and Murk; x4)


  • As seen in Tummy Trouble, Upchuck is so far the only alien able to switch between the two races of his sample's species.
