Nanomech

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

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).

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

From a normal 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 round the Omnitrix similar to Stinkfly. His legs have also changed shape.

Powers and Abilities
Nanomech has the ability to fly, and fire green bioelectric energy bursts from his hands.

Nanomech can shrink to microscopic size.

Nanomech can return to his normal size, but can't grow any bigger.

Nanomech’s wings glow when he flies.

Nanomech is very agile and fast.

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