First Appearance: Wonder Woman 14 (1945)
Creators: Alice Marble and HG Peter
Abilities: Nazi spy armed with pistols, grenades, and good old-fashioned greed and charm.
Backstory: Rudolph Hessenpfeffer was a clever Nazi spy and murderer known as the “Gentleman Killer”. Like any good spy, The Gentleman Killer was manipulative and relied on a number of natural abilities, like lies and deceit, to keep himself ahead of his pursuers. In a series of escalating conflicts, he would menace Wonder Woman and the denizens of a new mysterious realm.
While on the run from Wonder Woman and her allies, the Gentleman Killer and Diana are transported to a pocket dimension known as Shamrock Land, where the native Leprechauns are technically just as troublesome as Hessenpfeffer, but that doesn’t mean they don’t need rescuing! The Gentleman Killer manages to elude Diana, and escape to underground caves. Not knowing that he is an invader and criminal, he is welcomed by the Princess Elaine. Both charming and masterful in his deceptions, he would lie his way into a position of power, becoming the new Prime Minister of Shamrock Land, who rules with a greedy hand- even convincing the tribe of leprechauns to trade away their magical darts. Diana must shake off the stupor created by magic moonbeams to oppose him and rid the realm of the menacing Nazi thug.
