Appears in Death of Ben 10

Gutrot is the Omnitrix's DNA sample of an unknown species from an unknown planet in Earth-1010.


Gutrot has the appearance of a mechanical humanoid in a green outfit. He has a purple-flesh head and shoulders, with white gloves. On his stomach is a window, within which his internal chemical lab can be seen. The Omnitrix symbol covers the area that would, for most humanoid species, be the mouth.

Powers and Abilities

Gutrot possesses an incredibly in-depth knowledge of chemistry, innate to the form. He fully understands the effects of any kind of chemical and has a database-like knowledge of chemicals that he can create and use. He is also generally quite intelligent.

Gutrot's innards contain many elements and compounds that can be mixed and altered to create a plethora of different gaseous chemicals. He is effectively a walking chemistry lab. He can expel the gasses created within from any of the nozzle-like orifices located around his body.

Chemicals Gutrot is shown to produce include:

  • Potassium Bicarbonate - KHCO3
    • Fire Extinguisher fluid. Great for putting out fires.
  • Oxygen - O2
    • A highly explosive gas. Great for fuelling fires. Also required for human survival.
  • Methane - CH4
    • A highly explosive gas.


Wind can unintentionally move the gasses he tries to generate.

Gutrot must use any flammable gasses with care.

Gutrot's gasses may prove futile against suitably shielded opponents Gas masks, for example, may hinder his attacks


Death of Ben 10

Ben Prime used Gutrot to help Ultimate Ben 10 infiltrate San Diego Ironworks in Chapter 14.

Both Ultimate Ben 10 and Ultimate Ben 10'000 used Gutrot in Chapter 16: Part 2 to help defeat Ollopa. They used Oxygen, then Methane (to compliment Ben 23's use of Mr. Mucky) to fuel Ollopa's fire. Due to the nature of Ollopa, this weakened him to the point of passing out.
