The BG-011B Build Burning Gundam is a Gunpla from the anime Gundam Build Fighters Try. Designed and built by Sei Iori, it was piloted by Sekai Kamiki.
The Build Burning Gundam is a Gunpla designed for melee combat, its movement and mobility are noted to be similar to that of GAT-X105B/ST Star Build Strike Gundam, and this is not surprising as it is built by Sei Iori who used an earlier version of the Gunpla during the 11th Gunpla Battle World Championship. Due to its melee combat specialization, Sekai Kamiki can use the Gunpla and perform his Jigen Haoh School's style of martial arts without any problem.
Although the unit itself has no shield, it can use its elbow armor to protect itself against physical projectiles; this is known as 'pinpoint shield defense'. The Build Burning can be equipped with the 'Winning Knuckle' (a large fist formed from parts of the SD-237 Winning Gundam) or the Winning Gundam's Core Fighter to increase the power of its punch. The transparent blue parts on Build Burning's clavicle, forearms and lower legs are capable of storing Plavsky Particles for later emission. These parts are an application of the Star Build Strike's RG System and more of them are hidden below the Gunpla's external surface.
When the fighter unifies his senses with the Gunpla through powerful auto-suggestion, he assimilates with it and increases its performance by more than 3 times. In this state, the Build Burning's performance is comparable or even more than that of Star Build Strike with its RG System activated. While under assimilation, the Build Burning's last known specifications before hitting measurement error was Power Output - 1400, Mobility at 1200, and 0.11 in Plavsky Particle reaction speed. Assimilation can last as long as the fighter's willpower holds out, but its weakness is that damage to the Gunpla is reflected in the fighter's body.
When assimilation occurs with the Build Burning, the emitted Plavsky Particles will turn orange, and the transparent blue parts will also turn orange due to the change in the particles' color. The Build Burning also gains the ability to use fire in its attacks and fire effects can also be emitted from its back. These fire effects can be used to increase the suit's propulsion power. Unlike other Gunpla, the Build Burning's propulsion system does not produce standard particles or flames when activated, instead emitting Plavsky Particles.
