Biography
Zaardon, real name unknown, was a balding heavyset man who appeared to be in his mid-thirties and was a residence of Gotham City. Clearly a lunatic, he adorned himself in a black, textured costume, a helmet, and cape and began referring to himself as the Soul Reaper. A complete lunatic, Zaardon came under the influence of a man named Theo Galavan, whom Zaardon regarded as his master. Galavan gave Zaardon a mysterious blue drink and forced him to consume it. He then sent him out into the streets of Gotham to wreak havoc.

Former homicide detective Jim Gordon, now working as a traffic cop, witnessed Zaardon creating a scene on a busy sidewalk, shooting off twin guns and taking hostages. Gordon fought with Zaardon and apprehended him. He brought him back to Gotham City Police Headquarters and booked him under the name "Zaardon". Zaardon made sure that he spelled his name with two 'A's, and Gordon told him that he was a cinch for Arkham Asylum.

The blue elixir that Galavan had him drink caused Zaardon to cough up a powerful sedative in gaseous form. At Arkham, several patients were within the sphere of influence of the knockout gas, which enabled Theo Galavan to liberate them from the asylum as part of his plan to start his own super-villain team.
