"SD Gundam Gaiden: Knight Gundam Monogatari" (機甲神伝説) is the third entry in the SD Gundam Gaiden series. Originally launched in 1992 as part of Bandai's CARDASS card toy multimedia project, it was followed by a theatrical anime adaptation produced by Sunrise on March 1, 1993. Set in the world of Sukaia, the story follows Neo Zeon's search for the legendary "Sacred Mech" that grants dominion over the world. Their investigation leads them to the frontier village of Rugashi and its princess Bera. Knight Gundam GP01 and his comrades rush to the Royal Valley where the Sacred Mech sleeps, only to find it occupied by Neo Zeon's forces. After fierce battles between Knight Gundam GP01 and Knight Gundam GP02, the legendary Sacred Mech awakens and joins the fight, thwarting Neo Zeon's ambitions. Praised for its storyline and character design, this entry successfully blends Gundam elements with fantasy adventure across anime, manga, and games.
