Nanomech

Nanomech is a Humanoid-Nanochip from Nanomechia (non-canon). Nanomech is about a millimeter tall, can shrink and grow larger, has green wings, as well as one large green cyclopian-eye, carbon/silicon-based mechanical body, and triangular three-pointed feet. He is also the alien used to destroy the queen of the hive. The Omnitrix symbol is on his chest. Kevin describes Nanomech as "not like anything Ben has turned into before." This is because Nanomech is part human, part drone and thus making him a hive mind-based organism. From a normal sized perspective, when Nanomech speaks he has a squeaky little Voice, but from a Drone's perspective his voice is very deep.

Note: When Ben transforms into Nanomech, he shrinks, then his Nanomech skin covers his body. It is currently unknown why this happens (Though this maybe due to the fact that his DNA was put into use only soon after his DNA was added). This transformation is only in the movie. He might have regenerating abilities, due to the DNA of Nanomech is part of the Hive's insectoids.

Nanomech can fly, can shrink to microscopic size, produce wire-like tentacles from his back, fire green electricity from the tentacles and his hands, and the ability to adapt to most situations. He is noticeably more humanoid than the other drones (possibly an Omnitrix modification, as it alters DNA in order to achieve the form of a new species, and may have fused the cybernetics of the drones with Ben's own DNA in order to transform).he was first seen in ben 10 alien swarm.

In the Ben 10: Star Command Files episode, What's the Buzz, it is shown Nanomech can fire a green laser from his eye similar to Upgrade.
