Build Fighters, commonly abbreviated as BF, is the fictional timeline of the anime television series Gundam Build Fighters and its related projects.
Build Fighters takes place in a world much like the modern era, a few decades into the future. Technologically speaking, the main differences are more advanced holographic technology, and the presence of Plavsky Particles and related technologies such as the Gunpla Battle system.
Unlike most other Gundam timelines, the world of Build Fighters is almost entirely peaceful, with no major conflicts mentioned. The only Mobile Weapons are the real-life Gunpla models, based of the previous Gundam series, which all exist as fiction in this world.
The Build Fighters Timeline is one of the few timelines to date to include two separate dimensions; the main Build Fighters universe, and the universe containing the country of Arian. Not much information of Arian's world is shown, other than it does contain space colonies like most other lines in the Gundam saga.
Unlike other Gundam timelines, no exact dates are given for events.
