    Jiro Osamu was the body double for the original, aging Mr. Unknown, Japan's vigilante protector. His master would take part in the detective work while Jiro would fill in for any physical work Mr. Unknown would be required to take part in. But with the villain Lord Death Man appearing in Tokyo in order to kill all of it's Super Heros, Jiro's master is murdered, leaving him to take on the full time role of Mr. Unknown.


    Mr. Unknown was created by writer Grant Morrison, first appearing in issue #1 of Batman Incorporated, drawn by artist Yanick Paquett. Mr. Unknown was the first of many "international Batmen" that Morrison used in his new concept of Bruce Wayne's global franchising of the Batman identity.

    Jiro originally was essentially the backup to his master Mr. Unknown, but after the death of his master, he would attempt to take on the mantel of Mr. Unknown in order to help Batman. Instead of continuing to fight crime as Mr. Unknown, Jiro would be drafted into Batman Incorporated as the Batman of Japan.

    When Batman started his new crime fighting venture, Batman Incorporated, his first priority was to travel to Tokyo, Japan with Catwoman to recruit Japanese crime fighter Mr. Unknown. Unbeknownst to Batman, Japanese villain Lord Death Man had set out to kill all Japanese crime fighters and captured Mr. Unknown. After melting Unknown's hands off, Lord Death Man breaks a container of acid over his face, killing him.

Batman and Catwoman arrive to the scene, and with Batman busy fighting off the henchmen, Catwoman is left try and save the girl, despite her hatred of water.

    After the situation at Jiro's apartment is solved, Jiro's talks to Batman and informs him that while his boss, the original Mr. Unknown only did detective work due to his age, he was his body double and did all the physical aspects of the crime fighting job.
