Emil was a hard-bitten Belgian bounty hunter and sometimes mercenary. He had come to Gotham in search of a mysterious terrorist who is responsible for raining flaming chucks of debris and "Evil" Donald Pleasance down over the Belgian countryside. He was always accompanied by his assistant, Dennis, who was, in fact, a clone of Evil Donald Pleasance.

Emil and “Dennis” were killed in a gunfight with Falcone Gangsters on January 20, 1934 when the bounty hunters attempted to take Tony Farms--The Puma Man while he was guarding a union boss from the aforementioned gangsters.
