Goop is one of Ben Tennyson's alter-egos introduced in Ben 10: Alien Force. He is the Omnitrix/Ultimatrix's DNA sample of a Polymorph from the planet Viscosia.


Goop is a slimy single-cell organism that take various shapes. His usually appearance is a humanoid shape with pure green eyes and no visible mouth or nose. He has a small spike on his left shoulder and a long spike on his right shoulder, He has three fingers and a thumb on ease hand, and has two blobby feet, and wears the Omnitrix/Ultimatrix symbol on his chest. Floating above his head is a small UFO-like device which a Anti-Gravity Projector which helps stabilize his form due to his species having gravity weaker on Viscosia than most planets. 

In Omniverse, Goop has a more amoeba-like appearance with a beak-like nose, and has spikes on his shoulders and elbows. His Omnitrix symbol is now on top of his Anti-Gravity Projector rather than his chest. 

Powers and Abilities

  • Flight: Goop's Anti-Gravity Projector allows him to defy the laws of gravity.
  • Regeneration: Goop was able to regenerate from being punched in half, crushed, shot with lasers and exploding.
  • Shapeshifting: Goop can easily reshape his body to fit whatever purpose he needs.
  • Acid Manipulation: Goop can turn his body acidic to the point where he can melt a stone creature. He can also shoot acid out of himself.
  • Enhanced Agility: Goop is agile enough to dodge lasers.
  • Underwater Camouflage: Goop's physiology allows him to be completely invisible underwater.
  • Goo Projectiles: Goop can fire acidic projectiles made out of himself.
  • Limited Gravity Manipulation: Goop's AGP was able to generate a gravitational field strong enough to stabilize an entire planet and pull it together (though this required him to actually become the planet itself).
  • Enhanced Strength: Goop was able to lift two of Eon's minions into the air.


Goop's biggest weakness is his Anti-Gravity disk, if turned off or destroyed, Goop will lose the ability to maintain his form and will be unable to move as well as being reduced to a slimy puddle and completely immobilized. Despite not able to feel pain, Goop can still be harmed if he is spun really fast in a centrifuge. Goop cannot regenerate himself if he is attacked continuously. Goop can be blown away by a Geochelone Aerio's aerokinesis.
