Sentient Class-I Independent Operation Unit

The Sentient Class-I Independent Operation Units were a race of giant biomechanical sentient machines.

Physiology
The Sentient Class-I Independent Operation Units were composed of two sexes, male and female. Males would merge with the female, sharing its essence with his partner. Young units were born within the female for a time, and spent a time under the crust of planets, and incubated, they are born upon emerging from the surface and separating from their mother.

All Units are connected to one another, as they share a collective knowledge referred to as a Great River.

History
The Sentient Class-I Independent Operation Units once roamed the universe in pods, however many were killed during a random meteor storm, the survivors were conscripted into the Armor Hunters, who's leader, Control, saved some. They later began serving as mobile bases for the Armor Hunter squads.

Due to the Armor Hunter's fanaticism, the species wiped itself further into extinction. Only one is known to have survived.
