Jon Durr

Jon Durr

The Secretary of Science in the ruling Government Council headquartered in New Gotham City in the twenty-first century A.D., and the inventor of a revolutionary “experimental time-machine.” When Rak, Jon Durr’s evil assistant and twin brother, discovers that the fusion of Kryptonite with a fragment of the legendary hammer of Thor yields a new substance “with fantastic powers” which, accumulated in sufficient quantities, would enable him to establish himself as dictator of the entire planet Earth, he steals Jon’s time machine and travels into the past, to Gotham City in the year 1963 and then to ancient Norseland in the year 522 A.D., to obtain the kryptonite he needs and to steal the fabled hammer belonging to the Norse trible chieftain Thor. For a time, Rak’s scheme succeeds, but he and his henchmen are ultimately defeated and apprehended through the heroic efforts of Batman, Robin, and Superman (WF No. 135, Aug 1963: “The Menace of the Future Man!”) (TGSB).
