Furious Fighter Ben K

Furious Fighter Ben K (ベンK) is an armored warrior with a large hammer named after the legendary Saitō Musashibō Benkei. Ben K wins the honor to hunt down Metalder after defeating Gebaros in the Ghost Bank. He secretly attacks Ryusei by throwing a hatchet at his leg. With an injured leg, Ryusei leaves Mai behind and retreats into the woods. Ben K has the advantage with his mighty hammer, but Metalder manages to store just enough power to destroy Ben K's helmet. However, despite Metalder's wish to kill him, he spares Ben K's life upon realizing he was a human. After that, Ben K abandons the Empire. He returns in Episode 13 to help Metalder save Hidouman's captives, the miner and his family. He is killed by the Shadow Light Fighters, whom he simultaneously defeats. Like the legend, Ben K dies standing with arrows in his body. Aside from his hammer he has also used a pair of kamas.
