Formed via the PLANETS System by combining the compact Core Gundam (or Core Gundam II) with the Earth Armor support craft, it is themed after Earth, the third planet of the solar system. Serving as Hiroto's primary machine, it enhances base combat parameters to provide an all-round, highly versatile platform suitable for a wide range of combat operations.
Overview
The Earthree Gundam (PFF-X7/E3) is a mobile suit appearing in Gundam Build Divers Re:RISE, built and piloted by Kuga Hiroto. Formed via the PLANETS System by combining the compact Core Gundam (or Core Gundam II) with the Earth Armor support craft, it is themed after Earth, the third planet of the solar system. Serving as Hiroto's primary machine, it enhances base combat parameters to provide an all-round, highly versatile platform suitable for a wide range of combat operations.
Appearance
The machine features a signature blue-dominated color scheme and a traditional Gundam-style facial structure. It is constructed by equipping the underlying Core Gundam with external Earth Armor components. Visually, it is armed with two head-mounted vulcan cannons and two beam sabers stored on its back, while holding a customized beam rifle combined with armor components and a single shield in its hands.
Personality
As an inanimate Gunpla, the machine possesses no consciousness of its own, yet its battle demeanor directly reflects the calm and tactical mindset of its pilot, Kuga Hiroto. Designed without extreme specialization, it provides a stable and dependable base configuration that adapts flexibly to any combat scenario, silently embodying Hiroto's inner resolve and personal growth throughout his battles.
Abilities
Through Core Docking, the unit significantly boosts its core capabilities, delivering balanced performance across diverse combat situations. Its fixed armament includes two head vulcans and two rear beam sabers, alongside a beam rifle and shield. By connecting the beam rifle to the energy pack embedded inside the shield, it can recharge to unleash a devastating high-power beam shot. Additionally, it can perform seamless armor exchanges with other PLANETS System units and function as a sub-flight platform to transport allied machines.
Background
The machine was developed by Kuga Hiroto as the first armor unit under the PLANETS System, receiving its name from Earth through his interactions with Eve. Initially paired with a G-3 colored Core Gundam, it saw deployment in major GBN engagements including the Second Coalition War. During the conflict on Eldora, it served as BUILD DiVERS' main frontline unit, engaging in base defenses and convoy escort missions. Despite intense encounters against the rival Alus Earthree Gundam and having its armor temporarily hijacked by Alus in the final battle, it remained central to Hiroto's journey and triumphs.
Relationships
Kuga Hiroto is its builder and pilot, relying on it as his primary standard machine. Eve served as the conceptual inspiration behind its planet-based designation and design system. The adversary Alus analyzed its structure to produce the rival Alus Earthree Gundam and later forcibly combined with the Earth Armor during the final battle. Together with Kazami, May, and Parviz of the BUILD DiVERS team, the unit spearheaded numerous joint tactical operations.
Trivia
The name Earthree combines the word Earth with Three, symbolizing Earth's status as the third planet in the solar system. In real-world merchandise, it has received multiple Gunpla releases, including standard HG 1/144 kits, clear event exclusives, SD Gundam Cross Silhouette models, and Real Type color variations. In video games such as Mobile Suit Gundam EXTREME VS. 2 OVER BOOST, it appears as a 2500-cost versatile playable unit capable of dynamically swapping between multiple PLANETS System armors.
