Leon Dirken started a career in chemistry with good intentions. He took a job with a pharmecudical company and met a brilliant, yet mentally unstable young woman who became obsessed with him. Due to his overwhelming narcisissm, he looked beyond her faults and enjoyed the attention.

When a superior caught him stealing medication, Leon started to draw up plans to murder the man instead of risking his job. He quickly arranged a meeting between himself, his superior, and his unbalanced girlfriend. Using experimental drugs he had previously stolen, Leon arrived early and brought himself to a death-like state in his superior's office. The young woman assumed that Leon had been murdered, and in turn attacked and killed his superior before committing suicide alongside her beloved.

Though the crime was never suspected to be anything more than a crazed murder/suicide and Leon had gotten away clean, he still dediced to quit the position. He had found something much more interesting to do with his time.

As Killer Cadaver, Leon offered his services to various criminals. He arranged to be found "dead" at a phony murder scene, and would infiltrate police stations once left alone in the morgue. Everything from evidence to files to confiscated drugs disappeared by leaps and bounds due to Killer Cadaver's deception. He would often hide a lock pick and a tightly folded Halloween mask on his person for any sort of emergency.

Killer Cadaver remained completely unknown to the authorities for the entirity of his career under this name. However, eventually death almost caught up to him when a disgruntled employer meddled with Leon's drug stockpile, extendeding the death-like state by many hours.

Leon was drugged so heavily that he only became able to move during his own autopsy, when his chest had been cut open and his ribs spread. The examiner was barely able to repair the damage done in a haphazard fashion as Leon screamed, lashed out, and had to be restrained by several officers.

Several years passed without an appearance from Killer Cadaver. What no one knew is that Leon Dirken spent that time gradually going insane, confining himself to a mausoleum. After cutting and recutting himself over and over again, he was left with a face not unlike a Halloween mask. He emerged from his self-imposed Hell as Necropsy, having now moved into the territory of violent, vicious, psychotic killer.

Leon Dirken all but ceased to exist at that moment, and was replaced by a twisted shell of his former self. He had been a criminal, to be sure, but now he was something much worse.

Necropsy sm


Necropsy has come to dispise the living, and seeks to end life wherever he may find it. He resides in a mousoleum and carries out vicious murders under the cover of night. Necropsy often leaves his victims ripped open, and occasionally spread across several city blocks.

The only human beings Necropsy will associate with is a handful of dark and disturbed young men and women who seek him out. Through this small "family" of sorts, he spreads an idealogy of torture and murder. However, even these followers are not immune to his hateful and cruel temper.

From the rare moments when Necropsy speaks of his former life, it is apparent that he does not know his death-simulating medication was originally tampered with. He seems to thoroughly believe that his mock-deaths drew the ire of the Grim Reaper itself. It's possible, but not confirmed, that he may be seeking to atone by delivering an actual death for every one he faked.
