Mercury Charsiuman was a character in Tatakae!! Ramenman. He was voiced by Takaya Hashi. Charsiuman was Victory Ramenman's elder disciple, but because he was not chosen to inherit the Touryuu Gokui Sho he ran away. Several years later he and Ramenman have a showdown, but he is defeated by the Moudatsu Houkai Ken. Though he seems to die, he reappears afterwards and competes in Emperor Wan's Tournament, only to be defeated by Dokuroken Gundam. (Source: Kinnikuman Wiki)
