Omnis are a race spread far throughout the galaxy. They are robots, but nobody knows where they came from. They were just spat out from the depths of space.
Omnis run on pure, raw carbon. They can't get enough of it. They tear up solar systems to find it. They will even tear up a Kiladako to get at the tiny carbon supply in the centre of their bodies. The two races hate each other.
Omnis are not strong, or intelligent, but their numbers are great. They are born in huge Omnis factories that can produce 10,000 per metric day each.
Omnis roam the galaxies, finding carbon-rich planets and turning them into wastelands. Each individual Omnis has a mouth in which it feeds carbon and converts it into power.
Omnis act as one. They all speak the same language, through their minds. They have no leader or gods. They think that they are gods and everything else is below them. That is why they call themselves the Omnis.
Relationships
Omnis do not believe in alliances. They are enemies to all, and see carbon-based races as food.
