Cool, but gross.

Gwen's opinion on Goop.[1]

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


Ben as Goop

Being a 200-pound,[merch 1] single celled-organism[DM 1] that is neither liquid nor solid but a colloidal suspension,[DM 2] Goop is a humanoid pile of goo that can take any shape at will. Goop has bright green eyes and an Anti-Gravity Projector that allows him to be mobile in Earth's gravity and also projects his voice. His brain is spread throughout his body.[DM 3]

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

In Heroes United, the black outlines around Goop's eyes were thicker.

In Omniverse, Goop has a nose-like beak and 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 looks mostly the same as Ben's Goop except his body, eyes, and the Ultimatrix on his Anti-Gravity Projector are recolored red.

Powers and Abilities

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[2] or adhesive.[3] He can shoot it in continuous streams similar to a water hose[2] or in blob-like projectiles.[3] He is even capable of spitting out either slime or acid despite having no visible mouth.[3][4]

Goop is capable of making himself[5][6] and his touch acidic at will.[7][8] His acid is also able to dissolve a large variety of materials.

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.[9]

Goop can produce multiple slime tentacles from his body to grab multiple opponents.[10]

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.[11]

Goop can breathe underwater, as seen when he was in the sewer waiting to ambush Ben.[12]

Goop can change his density depending on his desire.[DM 4]

Goop can pass under an enemy's foot in order to make them slip.[13][10]

Goop can stick and scale on walls without difficultly.

Goop can survive in intense heat, such as the one on his home planet Viscosia.[merch 1]

Goop can mimic the shape of simple objects to fool an opponent.[merch 2]

Similar to Ghostfreak, Goop has movable eyes.[DJW 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.[DM 5]

With his Anti-Gravity Projector, Goop has enough strength to dismantle a Techadon robot from the inside[14] and effortlessly subdue Magister Prior Gilhil, someone who could easily overpower an armored Osmosian.[15] 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 due to the edges of it being razor-sharp. In fact, if Goop is fast enough with his Anti-Gravity Projector, he can temporarily prevent a Methanosian from regenerating.[12]

Thanks to his Anti-Gravity Projector, Goop is capable of high-speed flight, being able to easily evade Trombipulor's shots.[16]


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 collapses into an immobilized puddle 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's Anti-Gravity Projector can be disabled by a shot from a Positron Blaster, which makes him spin around extremely quickly and then separate into multiple parts.[11]

Goop's Anti-Gravity Projector can be switched off.[6]

Goop can be hurt if he is spun really fast in a centrifuge, which will cause him to begin separating into his constituent compounds.[17]

While running, Goop is not very fast and cannot outrun humans.[18]

Goop cannot regenerate if he is being continuously attacked.[2][10]

Goop is vulnerable to being blown away by a Geochelone Aerio's aerokinesis.[19]

Goop is vulnerable to suction, as shown when he got sucked into Trombipulor's nose.[16]

Goop is vulnerable to an Evolved Galvan's energy beams.[20]

Goop can be affected by a Nemuina's sleeping dust.[DJW 2]

Goop is vulnerable to being hypnotized.[DJW 3]

Ben 10 Alien Force: Vilgax Attacks

Goop is a playable alien in the game.

Xbox 360, Nintendo Wii, PlayStation 2, and PlayStation Portable Versions

Due to the Omnitrix rebooting after Ben's abuse of the quick-change feature during his battle with an animated Mr. Smoothy mascot, Goop was temporarily locked until Ben's arrival on Terradino.

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.

Only Goop and Swampfire are available on Ben's arsenal upon his arrival on Vulpin.

  • Each alternate counterpart of Goop has a different color and flavor: Ben Prime's Goop is green/lime-flavored, Negative Goop is red/raspberry-flavored, Muck-A-Muck is blue/blue-raspberry-flavored,[DJW 4] Bad Goop is mint green/licorice-flavored, Mad Goop is orange/sour orange-flavored, Nega Goop is grey/black pepper-flavored, Benzarro's Goop is purple/grape-flavored,[DJW 5] Argitrix Timeline Argit's Goop is peach/peach-flavored,[DJW 6] and Gwen 10's is pink/strawberry-flavored.[DJW 7][DJW 8]
  • Goop is one of the five aliens who escaped from the original Omnitrix; the others are Way Big, Ghostfreak, Chromastone, and Spidermonkey.
  • Unlike other aliens, during night time scenes, Goop's eyes are shaded.
  • Ben believes Goop's voice prevents others from taking him seriously.[10]
    • When Goop speaks in Omniverse, a crackle of static is heard at the end of each line as if he is speaking through a walkie-talkie.
  • Goop's Anti-Gravity Projector isn't part of his Polymorph biology; he just has one due to the difference of gravity between Viscosia and Earth.[DM 3] The projector is created using the same mechanism in which nanomachines break down Ben's clothing during his transformations.[DM 7]
    • Goop's Anti-Gravity Projector became a substitute for the missing Anti-Gravity Multiplier on the planet of Piscciss.[18]
    • It was Derrick J. Wyatt's idea to put Goop's Omnitrix symbol on his Anti-Gravity Projector in Omniverse. In his first drawing, the Omnitrix symbol was supposed to be floating inside Goop.[DJW 9]


  1. Ben was able to easily remove the Omnitrix from Vilgax while the latter was Goop because the device wasn't bonded to him and not due to any possible inherent weakness with Goop's body composition.[DM 6]
