* CompleteMonster: In the 1939 film serial, the evil criminal mastermind [[BigBad the Wasp]], real name [[spoiler:Dr. Andre Bennett]], seeks to dominate the US's communication grids, using a series of bombings that target populated areas, including a dam. He also seeks a special radium device to give him the ultimate power he desires. When he tries to eliminate Mandrake, the Wasp even targets populated areas such as a train or large building with his bombings. In addition, the Wasp is also a [[BadBoss terrible boss]], gassing his subjects for [[YouHaveFailedMe failing him]] or even for [[HeKnowsTooMuch knowing too much]] about his organization, willing to stop at nothing to TakeOverTheWorld.
* FairForItsDay: Lothar being an African prince as well as the team muscle may seem very stereotypical. But compared to almost any other black characters in the forties and fifties, he was portrayed with much respect and dignity. He ''was'' originally just a ScaryBlackMan who accompanied Mandrake like a servant, carried luggage and beat people up if the plot called for it; he also tended to vanish whenever he wasn't needed in a story. [[CharacterDevelopment Upgrading him]] to an independent and smart [[TrueCompanions True Companion]] with lines and his own background story was a pretty huge advancement.
* GermansLoveDavidHasselhoff: Although he will never be quite as beloved in Scandinavia as Lee Falk's other creation, ComicStrip/ThePhantom, Mandrake is a very popular backup feature in the Scandinavian ''Phantom'' comic books.
