Tenmaou

"“Descend from the heavens! All-powerful messenger of the Underworld! Tenmaou!!” —Nobunaga's summoning call" Tenmaou (天魔王) was a strong demonic super robot, the flagship machine of Yomihara under the official designation "Six Heavens' War God Machine", (六天武神機) and the personal mecha of Nobunaga Oda, the main villain of Samurai Dragon Amatsu and the Lady in the Water. In Kaiju of Retribution Tatsura, it was reconfigured into the much more powerful Tenmaou -Type Destroy-.

Appearance
Tenmaou is a towering mechanical behemoth standing at 70 meters. Its Diabolium armor is obsidian black, with golden plates and linings all over the body. Its head is shaped like a shogun's helmet with golden horns, red visors on its face and a crest with white, yellow, green, blue, purple and red gems attached on its forehead. On its shoulders and knees are large golden V-shaped plates with purple lighting in the middle.

Samurai Dragon Amatsu
After Hiyoshimaru and Yakumo were defeated, the mastermind behind the crisis Nobunaga Oda revealed himself before the heroes. Yukimura Katsuki challenged Nobunaga in battle for the safety of Japan and the release of Shiranui Mizuki. Nobunaga accepted and unleashed his greatest creation yet, the menacing and towering mechanical monstrosity that was Tenmaou, which quickly overwhelmed Amatsu in combat.

Kaiju of Retribution Tatsura
Within fifteen years, the gravely-damaged Tenmaou was repaired and remodeled as Tenmaou -Type Destroy- with far stronger weapons and better enhancements. This version would fight in the Battle of Kyoto before it was destroyed when Amatsu sacrificed himself to bring it into the Sun, taking Nobunaga with it.

Tatsura vs. Hellbourne
With -Type Destroy- annihilated, the next incarnation of Tenmaou had to be made from scratch. It would have the same build as the original, but look radically different. That would come in the form of Tenmaou -Type The End-, to be piloted by Shiranui Mizuki.

Kaiju World War: Part 1
Tenmaou was seen as a prominent symbol of anti-kaiju combat and armies, both from the Underworld and the surface world, wanted to emulate its effectiveness in the battlefield. Therefore, they built entire lines of robots, using Tenmaou as basis. Tenmaou -Type Zero- would be built, mass-produced and used by the sections of the Underworld Legion, while on the other hand, the United States Forces branch of the Earth Defense Force would create Tenmaou -Type Five- that would support armies in anti-kaiju combat but not produced as much and on a rate as -Type Zero-.

Kaiju World War: Part 2
During the final battle against Ryuuji Kuroi, he conjured hundreds of apparitions of previously defeated enemies to fight on his behalf, which included several copies of the original Tenmaou, -Type Destroy-, -Type Five-, -Type Zero- and -Type The End-. These copies, along with Ryuuji himself, were soon all destroyed by the combined efforts of the Taimanin, Justice Alliance and Young Braves Brigade.

By the end of the War Against the Forbidden, other than a few standing models of -Type Five-, the only remaining version of Tenmaou that is still active is Tenmaou -Type God-, which proved to be Tenmaou's strongest incarnation, also piloted by Shiranui.

Abilities
Tenmaou's abilities, when shown and put into effective use in the battlefield, proved that the robot posed to be an extremely dangerous and strong adversary against Amatsu and other kaiju.
 * Diabolium armor – Similar to Hiyoshimaru, Tenmaou has armor that was forged in Diabolium, a powerful substance from the Underworld which when turned into metal can be made impervious to damage from almost all sorts of human weaponry. However, the substance is enhanced by dark magics to increase its defense in kaiju combat and give it additional advantages.
 * Conventional Invulnerability – Therefore, Tenmaou cannot be harmed by any form of conventional weaponry, even nuclear weapons.
 * Magic Immunity – Tenmaou's enhanced Diabolium armor rendered it so that it could not be affected by any magical spell, ability or effect.
 * Super Durability –
 * Super Strength –
