Mole-Stache[DJW 1] is the Omnitrix's DNA sample of an unknown species from an unknown planet.


Mole-Stache is a rodentoid alien with a green and black jumpsuit in which his ears stick out and also has a pair of white gloves. He has a big blonde mustache and beaver-like teeth, as well as a slight potbelly. He also wears a green and white belt in which the Omnitrix symbol is located.


Mole-Stache speaks in a stereotypical gentleman manner and tends to use high vocabulary.

Powers and Abilities

  • Malleable Mustache
  • Elastic Mustache
  • Comakinetic Combat
  • Mustache Flotation
  • Comakinetic Flight
  • Strong Mustache
  • Enhanced Strength

Mole-Stache's mustache is free-forming and about as maneuverable as any limb, able to stretch and form itself into a variety of shapes. While doing so, he can perform with it feats like wrapping enemies up, forming hands, catching drafts, and carrying himself around. It can also be used as a parachute or propellers.

Mole-Stache appears to have skill in hand-to-hand combat with the mustache, as he easily defeated Fistrick with it.[1]

Mole-Stache can fly by twirling his mustache around like a helicopter.[1][2]

Mole-Stache's mustache is strong enough to lift a truck[1] and a tree.[3] On his own and despite his small size, however, Mole-Stache is strong enough to carry a Revonnahgander with his bare hands while flying and without any trouble.[1]

Mole-Stache can dig into hard surfaces, much like a real mole.

If Mole-Stache's mustache is cut or shaved off, it would quickly regenerate.[DJW 2]

Strength Limit

Aside from his malleable mustache and derived powers, Mole-Stache has no visible skills, hence why Ben regarded him as a useless alien upon transforming into him for the first time.[4]

Mole-Stache can have trouble staying upright while carrying something as heavy as a truck with his mustache.[1]

Mole-Stache's name is a portmanteau of the words "mole", referring his appearance, and "mustache", which alludes to his ability to fight with his malleable mustache.


  • Mole-Stache speaks with a British accent.
    • The reason for this is the British are stereotyped as gentlemanly.
  • Mole-Stache is one of four aliens unlocked by Driba and Blukic; the other three being Walkatrout, Pesky Dust, and The Worst.[4]
  • Ben 23 does not have an alternate counterpart to Mole-Stache in his Omnitrix.[5]
  • In his first appearance, Mole-Stache shared the same voice as Ben due to the Omnitrix malfunctioning. The out-of-universe reason for this was because the crew originally did not envision him as a usable alien for later episodes.[DJW 4] Mole-Stache's voice was eventually changed in Breakpoint because the crew liked how he turned out.[DJW 5]
  • Mole-Stache was initially planned to appear in No Honor Among Bros, but the scene had to be cut for time.[DJW 3] During said scene, Ben would have learned how to use Mole-Stache's powers while fighting Yetta.[TJ 1]
  • Albedo's Ultimatrix does not contain Mole-Stache's DNA.[DJW 6]
