Metal Hero Series
Other similar heroes, such as "Nebula Mask Machine Man", "Kyodai Ken Byclosser", "Lady Battle Cop", and "Choukou Senshi Changéríon", were also produced during the time that the Metal Hero Series were on the air, but are not included as part of the Metal Hero Series for various reasons. "Machine Man" and "Bicrosser" were created by Shotaro Ishinomori, while Changéríon's armor is not metallic. It's unknown if Lady Battle Cop is part of Toei's shared universe.
