The Baterra were a generation of mechanical beings, created by the Great Beings, to fight in the Core War.
After the Great Beings had failed to end the Core War in peaceful ways, they eventually built the Baterra, robots designed to kill every being wielding a weapon.
After the Shattering, several Baterra ended up on Bara Magna. They encountered the Skrall, and pushed them south, towards the desert.
- The Bohrok were similar to the Baterra in terms of appearance.
