The TBG-011B Try Burning Gundam is a Gunpla introduced in the anime Gundam Build Fighters Try. Piloted by Sekai Kamiki, it is an upgrade of the BG-011B Build Burning Gundam.

Compared to its predecessor, the BG-011B Build Burning Gundam, the Try Burning has reinforced joint armor and is installed with a new system known as the "Burning Burst System" to maximize its Plavsky Particle emission. Similar to the Build Burning, the Try Burning's transparent blue parts are for storing Plavsky Particles for later emission, and more of them are hidden below the armor. Although the suit has no shield, it can defend against projectile and ranged beam attacks using its elbow armor like its predecessor. The suit can also release Plavsky Particles from it soles in an attempt to protect itself from attacks below. Normally, these Plavsky Particles are used for propulsion, much like those released from the Gunpla's back.

When Sekai assimilates with Try Burning, its performance improves by more than 3 times and the transparent blue parts turn orange from the change in the Plavsky Particles' color. Furthermore, all the Plavsky Particles stored in the suit can be released at once, and this causes the entire Try Burning to be engulfed in flames. The suit also gains the ability to generate a barrier during assimilation. The weakness of assimilation is that the damages sustained by the Gunpla are reflected onto Sekai. Before the finals of the U-19 Championship, the Try Burning was remodeled so that its polycaps are interchangeable with that of its teammates. This allows the damaged Try Burning to be repaired using its teammates parts, allowing it to fight properly during the overtime battle as the team's representative.
