The LGZ-91 Lightning Gundam was a custom Gunpla built by Yuuma Kousaka of team Try Fighters. It was based on the RGZ-91 Re-GZ from the 1988 anime film Mobile Suit Gundam: Char’s Counterattack. The Lightning Gundam retained the anime version’s ability to transform into a waverider mode by combining with its Back Weapon System. Yuuma’s customized Lightning Back Weapon System could function as a separate unit, and in waverider mode the Lightning Gundam could transport another Gunpla on its back. The Lightning Gundam’s shoulders featured a pair of high performance sensors that boosted the targeting range. The Lightning Gundam’s armaments included vulcan guns, a beam vulcan, beam sabers, missile pods, beam cannons and a handgun that could combine with other parts to form a rifle. Fumina Hoshino convinced Yuuma to return to Gunpla Battle and join the Try Fighters team as it competed in the 13th Gunpla Battle Japanese U-19 Championship. As part of Fumina’s support plan with her SD-237 Winning Gundam, modular parts from her Gunpla could combine with Yuuma’s rifle to form the enhanced Winning Launcher. When the Try Fighters advanced to the tournament finals, Yuuma upgraded the Gunpla into the LGZ-91Fb Lightning Gundam Full Burnern.
