* AcceptablePoliticalTargets: The Germans.
* AdaptationDisplacement: Unless you're French, you probably know the name "Lupin" as ''Franchise/LupinIII'' better than the ''Literature/ArseneLupin'' stories that inspired it.
* EpilepticTrees: The Arsène Lupin in ''NightHood'' lives in the mid-20th century and is somewhat colder than the early 20th century Lupin from the books. Because of that fans have speculated that NightHood's Lupin is actually the original Lupin's son, Lupin II and father of Franchise/LupinIII.
** If you want to carry this further, NightHood's Lupin might as well be the grandfather of LightNovel/AriaTheScarletAmmo's Riko Mine a.k.a. Lupin IV.
* OlderThanTheyThink: Manga/DetectiveConan fans might be surprised to know that Kaito Kid owes a lot to Lupin. From using the sleight of hand to steal jewellery to his dress code (with the only difference being that Lupin wore black while Kid wears white, and Lupin's cape didn't turn into a glider).
