Excerpt from an Astro City Police Department file:
Real Name: Josef Andros Platapopoulous
Aliases: The Platypus, Platypus Joe, Joe the Platypus, Joey Platypus
Born with physical anomalies that made him deformed and ugly, Platapopoulous had an early life filled with abuse and humiliation. Derisively nicknamed "The Platypus" at an early age, he determined to have his revenge on those that mocked him by making his childhood nickname into a name to be respected and feared.
Spending time in the Australian Outback, Platapopoulous claims to have had "dreamtime" visions that gave him mastery over other men, and mystic insights into the ways of power, but there is little or no evidence of this. Even his accent comes and goes.
At first the strategy appeared to be a huge success, with Jitterjack decimated whole squads from the rival gangs. With the gang war in full swing, each side seemed to blame the other and stepped up attacks on one another. But by the end of January with fighting mere blocks from his base at the Down Under Club Platypus realized there was somebody else behind the scenes controlling everything. As he was planning to make his escape, McManus finally revealed himself as the true power behind the gang war and the one with the actual backing of Pyramid. McManus murdered Platypus and by the morning was the controlling power of the Astro City underworld.
