Based on illustrations of a knight-style SD Gundam by Koji Yokoi, SD Gundam Gaiden features fantasy Japanese role-playing game styled visuals and storytelling, similar to the Dragon Quest franchise by Enix.
Characters are based on characters and mecha from Mobile Suit Gundam, Mobile Suit Zeta Gundam, Mobile Suit Gundam ZZ, Mobile Suit Gundam: Char's Counterattack and Mobile Suit Gundam 0080: War in the Pocket.
