I say, Mole-Stache! This is quite unprecedented!

– Mole-Stache.[1]

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

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. When reverting to Ben, his nose will also hurt.[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.


  • The design for Mole-Stache came from Jerry, drawn by Steven Choi and Chap Yaep.[DJW 4]
  • 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 5]
    • Mole-Stache's voice was eventually changed to a British accent in Breakpoint because the crew liked how he turned out.[DJW 6] Mole-Stache speaks with this accent because the British are stereotyped as behaving 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]
  • Mole-Stache was initially planned to appear in No Honor Among Bros, where he would master his powers during a fight with Yetta, but the scene had to be cut for time.[DJW 3][TJ 1]
  • Albedo's Ultimatrix does not contain Mole-Stache's DNA.[DJW 7]
  • There were no plans to feature Mole-Stache in the reboot because the crew envisioned him as being only being exclusive to the Ben 10: Omni-Charged game based on the show.[DR 1]
    • PHL Collective requested for Mole-Stache's inclusion in Omni-Charged,[DR 2] partially because he worked well with the VR mechanics for the game.[AC 1]
