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


Ben as Goop

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

In Alien Force and Ultimate Alien, Goop wore the Omnitrix/Ultimatrix symbol on his chest.

In Omniverse, Goop has a nose-like beak and he has an amoeba-like shape. His Anti-Gravity Projector has been redesigned and the Omnitrix symbol is on the top of it.

Albedo as Negative Goop

In Alien Force, Negative Goop looked exactly like Ben's Goop.

In Omniverse, Negative Goop is red and his Anti-Gravity Projector is white on the top with a red light on the bottom. Negative Goop's Ultimatrix symbol is on his Anti-Gravity Projector.

Powers and Abilities

  • Shapeshifting
  • Elasticity
  • Flight
  • Acidic Slime
  • Acidic Touch
  • Slime Spit
  • Slime Tentacles

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

Goop is able to generate and shoot slime from any part of his body. The slime he generates can either be acidic[1] or adhesive.[2] He can shoot it in continuous streams similar to a water hose[1] or in blob-like projectiles.[2] He is even capable of spitting out either slime or acid despite having no visible mouth.[2][3]

Goop is capable of making himself and his touch acidic at will.[4][5][6] His acid is also able to dissolve a large variety of materials.

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

Goop can produce multiple slime tentacles from his body to grab multiple opponents.[7]

Goop can regenerate and rebuild himself with ease.

Goop possesses enhanced strength and can increase the impact power of his attacks by stretching himself backwards and using the recoil to launch enemies with a single punch.[8]

Goop can change his density depending on his desire.[DM 1]


Goop's Anti-Gravity Projector allows him to change his shape, form, length, width, and height at will, as well as granting Goop the ability to fly and levitate. If Goop loses his Anti-Gravity Projector, the Omnitrix/Ultimatrix can immediately generate a new one.

With his Anti-Gravity Projector, Goop has enough strength to dismantle a Techadon robot from the inside[9] and effortlessly subdue Magister Prior Gilhil, someone who could easily overpower an armored Kevin.[10] Goop has even defeated both Gwen and Kevin in combat with both his strength and slime.

Goop can control and launch his Anti-Gravity Projector at enemies to attack them, the edges being razor-sharp.[11]


Primus (512)

Goop rendered immobile

Goop is limited to his Anti-Gravity Projector controlling his body. If it is separated from him by more than two feet or turned off, Goop's body goes completely inert until it recollects it. He can only struggle to move, since he cannot change shape or make appendages to move without his Anti-Gravity Projector.

Goop can be hurt by being spun really fast in a centrifuge, which causes him to begin separating into his constituent compounds.[12]

Goop cannot reform if he is being continuously attacked.[1]

In Alien Force and Ultimate Alien, because of his slime body, Goop's Omnitrix/Ultimatrix symbol could be easily pulled off, reverting Goop to normal and removing the original Omnitrix/Ultimatrix from the user.[13] He now lacks this weakness in Omniverse, however, as the Omnitrix symbol is on his Anti-Gravity Projector.


  • In Primus, Ben turned Vilgax into Goop and pulled the Omnitrix off his chest, removing the Omnitrix from Vilgax.

Goop has the ability to stick to slime-covered walls and wall jump, thus reaching otherwise inaccessible areas.

Acid Hose is an unlockable combo move for Goop.

Goop is vital for progression on the Terradino, Mor' Otesi and Null Void levels of the game.

Goop is a playable alien in the game.

Due to the Omnitrix sorting out after Ben fiddled with it, Goop was temporarily locked. Goop was reunlocked at the beginning of Level 10.
