This is known of Tiger Hart.
- He was created by Fletcher Hanks.
- He is (or was) a man at his physical peak.
- He appeared in one story, in what Jupiter is described to be very similar to medieval Earth of legends.
In that story, Sohinoor-diamond (which had been stolen from all of its owners, who all had faced terrible misfortune) and princess of Jupiter had been stolen by a violent barbarian. He retrieved them both. The barbarian chased him down, with his men. Just before he would`ve had to fight against the cruel man, he destroyed the diamond, deeming that it has caused too much suffering. It is not known who won the brawl between Tiger Hart and the crooks, but most likely, it would`ve been Tiger Hart.
