Nanochip

Nanochips (aka Microchips or Nanites) are a biomechanical alien species.

Biology
Nanochips are tiny mechanical insects that come in two known colors: blue or a combination of red, yellow, and orange. They operate in a hive and are produced by a Queen.

History
The Queen produces them from her body and, after she takes up residence in Victor Validus' body, she produces them from there and they have the ability to take over a person's mind. The Nanochips are hybrids which are part organic matter and part machine, as pointed out by Kevin Levin. The Queen was destroyed by Ben in the form of Nanomech.

Surprisingly, the nanochips returned, and the team discovered that the chips took over Elena Validus' mind and had made her the Queen of the Hive. After Elena sacrificed herself for Ben by destroying her nano self, the chips still had some life in them.
