Hakai-O (ハカイオー Hakaioo) is a commercial LBX model product manufactured by Prometheus. It serves as Hanzou Gouda's personal LBX in the Danball Senki series.
- Haganjin (破岩刃): Hakai-O's trademark heavy sword.
- Gaou Cannon (我王砲): Hakai-O's installed attack function. Enery is charged through the cannon's funnels and then fired towards the opponent, destroying everything upon impact. The only disadvantage for this function however is that once fired, the model's systems will shut down temporarily, making it vulnerable for attack.
- Its Bandai model is ranked 10th in the LBX Popularity Poll Ranking Special.
