Hiro Okamura, is a teenage mechanical genius from Japan with an IQ of 210. First appearing as Toyman when he targets Metallo, claiming the cyborg's body was based on a material stolen from his grandfather.
He later aids Superman and Batman in destroying a kryptonite meteor that threatens the Earth and strikes a deal with Batman to provide him with various technological implements. Many of his inventions are inspired by anime and manga, including giant mecha (notably his giant Composite Batman-Superman robot).
Through Superboy and Robin III Okamura has a honorary membership with the Teen Titans and through Batman and Superman, an honorary membership with the Justice League of Amercia. Okamura joins Robin and the other Teen Titans at the Titans Tower for Superboy's funeral, clutching a Superboy Action Figure.
In Superman/Batman #45, he offers to assists the duo in their quest to rid the world of Kryptonite, using spider-like nanobots to collect Kryptonite molecules in the air. His offer becomes a necessity as Lana Lang, in a last-ditch effort to get rid of Kryptonians and keep Lexcorp afloat, turns a set of Kryptonite caches into "dirty bombs", which irradiate the entire planet. Hiro comes to the save, settling for a Power Girl-bot to "date". Instead, he gets his dream date, a dinner in Paris with the real Kara, and the status of honorary member of the Justice League.
A future version of Hiro, allied with the Titans Army, travels back in time to modern day to cement their power-base in Teen Titans #52.
