Earth-Two Roh Kar[]
He was Martian, and he was a Manhunter, but he was not the Martian Manhunter. AFAIK there's no record (at least in any Golden Age comics) that he ever met J'onn J'onzz. Roh Kar only appeared in one Batman story, in Batman #78, Aug 1953. Stoop Davy Dave (talk) 12:25, December 2, 2016 (UTC)
