Goop is the Omnitrix's DNA sample of a Polymorph from the planet Viscosia.


Goop is a humanoid pile of goo that can take any shape at will. He has an Anti-Gravity Projector that allows him to be mobile in Earth's gravity and also projects his voice. Goop wears the Omnitrix symbol on his chest.

He has a green slime body, bright green eyes, and a gunmetal Anti-Gravity Projector on top to keep him on his gravity.

Powers and Abilities

Goop is indestructible, making it difficult to defeat him by attacking his body.

Goop can stretch, bend and deform himself into any shape or form.

Due to being made of slime, Goop can hold objects inside his body. He can also do this with individuals to protect them, as shown when he rescued the Piscciss Volann Prisoner.[1]

Goop can regenerate and rebuild himself with ease.


Goop's Anti-Gravity Projector allows him to change his shape, form, length, width, and height at will, and grants him the ability to fly and levitate.

Goop's Anti-Gravity Projector can increase its gravitational pull, allowing it to pull Goop along when he has extra weight inside of him.[1]


Goop is limited to his Anti-Gravity Projector controlling his body. If it is separated from him or turned off, Goop's body collapses into an immobilized puddle until it recollects it or until ben reverts back to normal.

  • Goop was incorporated into the reboot exclusively for Ben 10 Versus the Universe because he is considered a favorite of the crew.[DR 1][DR 2]
  • Goop's design in the reboot is heavily resembles his Classic Timeline counterpart's appearance in Alien Force and Ultimate Alien but with elbow spikes similar to his Omniverse design.
  • Goop has only been referred to as "the booger guy" by Ben and Azmuth; his name is listed in the end credits of the movie.
  • Goop is the first regular alien featured in the reboot to only be used once on-screen; this trend would continue with Way Big, Spidermonkey, and Buzzshock.
