This is the form that Godmaru inherited from the Kidou Daishougun's Armor, which holds the power of Tentei, the pinnacle of Heaven Warriors. The Kidou Daishougun's Armor was said to be hidden within the Mobile Heaven Castle, which itself was a gigantic suit of armor. Godmaru donned this armor to fight against Masei, who had absorbed the Tengaiou and become the Batou Daishougun, and became the Cho Kidou Daishougun. The Tenoh Sword can also be used to unleash Godmaru's special move, Phoenix Flame Phoenix Slash, which has reached the realm of Flame Water.
The Sky Phoenix Wings, which spread from both shoulders and contain the power of the phoenix, are made of Crystal Kirahagane, a treasure of the heavens, and are said to enable the wearer to fly freely through the sky. It is possible that the person who is said to have defeated a legendary monster in the past was also a person from earth who wore this armor.
