The AGP-X1/E3 Alus Earthree Gundam (アルスアースリィガンダム?) is a variant of the Alus Core Gundam that appears in Gundam Build Divers Re:RISE and is piloted by Alus. It can also be piloted by the Guard Eye, and in this state, it is known as Eldora Earthree Gundam.
The Alus Earthree Gundam was created independently by Alus through analyzing Hiroto's PLANETS System and is developed based on the combat data of the Earthree Gundam. It thus has the same exact structure as the Earthree Gundam and is likewise formed through the docking of the central Alus Core Gundam with the Alus Earth Armor. Its capabilities are also similar to the Earthree Gundam's, being most effective when used with a basic battle style and is capable of handling any situations. Like the Alus Core Gundam, the sensor on the Alus Earthree Gundam's head glows red when it is controlled directly by Alus. This glow is not present when the machine is operated by the Guard Eye, and in this state, it is known as Eldora Earthree Gundam.
