This article is about a/an hero in Choujinki Metalder.
"Wind, Clouds, Sun! I ask you from the bottom of my heart- why was I born in the world like this?! (風よ、雲よ、太陽よ!心あらば教えてくれ。なぜ、この世に生まれて来たのだ?! Kaze yo, kumo yo, taiyō yo! Kokoro areba kotaetekure. Naze, kono sekai ni umaretekitanoda?!)"
―Metalder after his first fight with Coolgin.[src]

Metalder (メタルダー Metarudā?) is a "Choujinki", a powerful war android built by Dr. Koga at the end of World War II originally as a countermeasure against the Americans. He was hidden in a secret base of the Japanese Imperial Army until Dr. Koga activated him years later to fight the Neros Empire. Whenever his energies reach a peak from rage, with the cry "Ikaru!" (怒る!? "Anger!"), he transforms into his metallic form. Powered by 'super-gravitational energy', his killing techniques include "Laser Arm", "G-Kick", "Metal Tornado" spinning kick, "Head Crash" ram, "Plasma Punch", "Metal Bomber" punching attack from above, And "1000 Hand Punch".


Choujinki Metalder

He was hidden in a secret base of the Japanese Imperial Army, the Silver Carcass, until Dr. Koga activated him years later to fight the Neros Empire.

Metalder lived in the Silver Carcass with Springer, a dog that was able to speak through a machine created by Dr. Koga. He had a human guise known as Ryusei Tsuguri. His two friends were Mai Ogi and Hakko Kita who both became aware that he was Metalder shortly after meeting him.

At the end of the series he defeats God Neros but in the process, his super-gravitational energy is greatly damaged, as a result whenever he moves longer, he will explode and the world will be destroyed by its impact. With Kita's help, Metalder is spared from destruction, but at the cost of his human form and his ability to fight as a Choujinki.
