|This article is about a/an hero in Choujinki Metalder.|
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".
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.

His human guise, Ryusei Tsurugi (剣 流星 Tsurugi Ryūsei?), is directly modeled after that of Dr. Koga's son Tatsuo of whom he lost during the war.

The Metalder Key (メタルダー Metarudā Kī?) is a Metal Heroes Ranger Key released as part of the Ranger Keys Metal Hero Edition in Bandai Premium. It is unknown if it will appear in a future crossover. Of course as with all Ranger Keys, should it exist, it would be able to transform one, i.e. one of the Gokaigers, into Metalder.
