Gundam Build Fighters (Japanese: ガンダムビルドファイターズ, Hepburn: Gandamu Birudo Faitāzu), often abbreviated as GBF, is a 2013 Japanese science fiction anime television series based on Sunrise's long-running Gundam franchise.

The series was first unveiled under the name "1/144 Gundam Mobile" project by Sunrise,[1] before its official announcement.

As the only child, his family owns a small Gunpla shop and his talent is well-honed, however his weak piloting abilities have led him to a series of first-round losses.

Once the GP Bases are set, the Battle System (バトルシステム, Batoru Shisutemu) disperses "Plavsky particles" (プラフスキー粒子, Purafusukī Ryūshi, a portmanteau of "plastic" and "Minovsky particles"), which react only to the plastic material of Gunpla and animate them into the game.

A Gunpla's combat statistics are determined by its build quality; modifications such as adding scratch-built parts and paint weathering will increase its stats.

The 16 Gunpla Fighters with the most points will advance to the final tournament, a knockout stage that decides the World Champion.

It is later on revealed that Plavsky particles are processed from Arista (アリスタ, Arisuta), a crystal originating from Reiji's home country of Arian (アリアン).
