Dr. Jonathan Ohnn debuted in 1984’s Spectacular Spider-Man #97, and he made his first official appearance as The Spot in the following issue. Ohnn was a scientist working for The Kingpin, researching ways on how to duplicate the radiation levels of the superhero Cloak as a way to mimic his powers. Ohnn succeeded in opening one of these black portals, but the experiment required so much power that New York City experienced a blackout, and fearful that the portal would close, Ohnn stepped through it and found himself in another dimension, although not the same one that Cloak access when using his powers.
