The Try Fighters (トライ・ファイターズ, Torai Faitāzu) are the main protagonists of the series and are based at Seiho Academy (私立聖鳳学園, Shiritsu Seihō Gakuen), the same alma mater as the core characters of the previous season.
Initially the underdogs in the sport, the Try Fighters fight their way to become the West Tokyo Champions and secure a spot in the national championship.
Team FAITH (フェイス, Feisu) represents Joto Municipal Middle School (常冬中学, Jōtō Chūgaku).
The team is named after FAITH (Fast Acting Integrated Tactical Headquarters), an elite division of ZAFT from Mobile Suit Gundam SEED Destiny.
Team Von Braun (フォンブラウン, Fon Buraun) represents Granada Academy (グラナダ学園, Guranada Gakuen) of Tokushima Prefecture.
The team consists of former Argentine Gunpla Battle Champions Mario and Julio Renato and their younger brother Serio.
The configuration of these units is a nod to the titular mecha trio of Sunrise's 1987 anime series Metal Armor Dragonar.
The team is singlehandedly defeated by Lucas Nemesis' Crossbone Gundam X1 Full Cloth in the quarterfinals of the national tournament in episode 20.
