History

The Guard Eyes were weapons created by Alus to protect Eldora from outside invaders. Believing the mountain-dwellers to be invaders, Alus used them to attack the mountain-dwellers. For a time, the Guard Eyes were opposed by Masaki Shido and Cuadorn. However, Alus eventually captured Masaki and brainwashed him into serving him. After presumably learning about the existence of Gunpla Battle Nexus Online from Masaki, Alus created mobile suits based on the Gunplas from GBN, with the Guard Eyes functioning as their control units. Because of the Guard Eye's monoeye, Alus' army was named "One-Eyes" by the mountain-dwellers.

Some time following the defeat of its creator, Alus, one surviving but stranded Guard Eye was found by Calico and Zabun. Initially frightened, the Guard Eye later accepted their offer of riding their vehicle.
