Ryushou and Hishou, who were resurrected by the power of darkness, are united by using their newly acquired power, Ryuhi Hengen transformation technique. They are waiting with their Darkness Army at the Anaheim Mountain where Shodai Gundam Daishogun and others are heading. The two have been greatly enhanced by the power of darkness, and their combined power is immeasurable. The Flying Dragon Cannon, which combines the Ryushou's Dragon Flame Cannon and the Flying Twin Swords of Hishou, is a weapon so powerful that it can burn the entire area to a scorched wasteland with one blow. In addition, Ryushou's armor sword that was on Ryushou's back is attached to his arm, and his fighting ability has also improved significantly, making it difficult to defeat even Shodai Gundam Daishogu and Ikazuchi's combined attack.
