Fan Casting Toymaster in Return to the DC Universe

A mechanical genius from Japan, Hiro Okamura is always seeing the big picture. He first met Superman when dealing with Metallo, due to the metal that makes up Corben's new body is something his grandfather worked on, and was taken by Emmett Vale. Becoming an ally to Superman, Hiro would help him and Batman save the planet from a Kryptonite meteor among other ventures, even becoming friends with Conner Kent's Superman and Red Robin. Thought to be a robot made by Winslow Schott, Hiro is very real, now calling himself "Toymaster" as he works with the JLA's support staff at the Hall of Justice.
