Nanomech is the Omnitrix's DNA sample of a Nanochip.


Nanomech is about an inch tall at full size. He has grey skin with a green circuit-like design on it. Nanomech possesses green wings as well as one large, green cyclopean-eye. His body is a carbon/silicon-based alloy, and he has triangular feet. He wore the Omnitrix/Ultimatrix symbol on his chest.

From a human-sized perspective, when Nanomech speaks, he has a squeaky high pitched voice, but from anything of his size's perspective, his voice is very deep.

In Omniverse, Nanomech's circuit design is gone, being replaced with a design pushing more to his Alien Swarm design, and the Omnitrix symbol is where his eye was. He has different wings, he speaks with a more robotic tone, but still high-pitched and he has four small eyes around the Omnitrix similar to Stinkfly. His legs have also changed shape. His body also emits a bright green glow that completely surrounds him.

Nanomech's bioelectricity and flight

Nanomech has the ability to fly. He is very agile, and his wings glow when he is airborne.

Nanomech can reduce his size, even to microscopic scales. He can return to his original size, but cannot grow any larger.

Nanomech can launch green bioelectrical energy from his hands, ranging in forms from beams to orbs.

Nanomech has the ability to adapt to his opponents. This ability was first confirmed and displayed in Alien Swarm, but has not been looked into since.


Nanomech's size can be a problem if fighting larger opponents. In Inspector 13, this is proven true when Kevin as Nanomech was harmed by a fly swatter.


Alien Swarm

  • Nanomech first appeared in Alien Swarm. Nanomech was unlocked by scanning the Nanochips. Also, Nanomech destroyed the Decoy Queen of the Alien Chip hive. He was used to enter Victor's brain and battle the queen. After a grueling battle, Nanomech destroys the Queen and thus the entirety of the chips, freeing everybody from their control.

  • During the Birthday Bash in Cartoon Network Universe: FusionFall, players could get a Nanomech helmet that looked like his live action movie version. But after Ben 10: Ultimate Alien premiered, it changed to match the cartoon version. This item has been re-released as a code item.
  • Kevin states that he can't take Nanomech seriously because of his voice.
  • According to Dwayne, Benchip was Nanomech's working name.
  • According to Inspector 13's technology, Nanomech is an unknown bio-mechanical organism. The Plumber's scanners see him as an unknown bio-mechanical creature. 
  • In the movie, his voice is deeper and sounds robotic, while in the series, he has a high, squeaky voice.
  • Kevin describes Nanomech as "not like anything Ben has turned into before" because Nanomech is part human/part drone and thus makes him a hive mind-based organism (so he is a Human/Nanochip hybrid).
  • Nanomech is the only one of Ben's aliens that is part-human.
