Baterra

Baterra were mechanical shapeshifters created by the Great Beings that lived in the northern parts of Bara Magna.

History
After failing to end the war over the Energized Protodermis, the Great Beings created the Baterra to kill every armed combatant of the war. After the Shattering, the Baterra became stuck on Bara Magna, but continued to attack armed inhabitants. When the Skrall moved north, the Baterra killed many of the leader class Skrall, leaving only Tuma to lead the Rock Tribe.

The Baterra ambushed their enemies by shapeshifting into a tree or something else that fit into the environment. Then, when an enemy strayed by, they quickly shapeshifted into their default form, killed the victim and shapeshifted back before anyone could turn to see what had happened.

Empire of the Skrall
In Empire of the Skrall, Branar was sent on a mission by Tuma to find out if the Baterra were moving to the south or not. However, the Baterra were indeed moving to the south, and almost all his fellow skrall warriors, and most of the vorox were killed. The Baterra let Branar escape to send a warning to the Skrall.
