* AccidentalInnuendo: see HoYay
* AlternativeCharacterInterpretation: In ''Le Journal d'un ingénu'', did Kassandra Stahl truly love Spirou? Or was it just a ploy to convert him into a [[DirtyCommunists communist]]?
* EpilepticTree: Is ''ComicStrip/LePetitSpirou'' Spirou's son or Spirou when he was young? Stories suggest both ideas!
* EnsembleDarkhorse: The Franchise/{{Marsupilami}}.
* FanonDiscontinuity
** Morvan & Munuera tried to integrate elements from all their predecessors into their run (including Rob-Vel and Fournier), but unfortunately for them many fans wrote off the series after the departure of Tome & Janry.
* FoeYay: Fantasio and Seccotine.
* HarsherInHindsight: In the ''Le Groom vert-de-gris'' Spirou is saved from [[ThoseWackyNazis Nazis]] by a Jewish girl. After the war, he decide to ask her out, but learns that [[FinalSolution she was taken in a train by guards]].
* HoYay: Spirou and Fantasio, [[HeterosexualLifePartners obviously]]. There are things like [[http://img80.imageshack.us/img80/799/fantasiomgoe6.jpg this picture]] to keep the rumors alive and kicking.
** '''Taken out of context:''' Fantasio wakes up, apparently in the same bed as Spirou. He's covered in a whitish dripping liquid. He shouts "'''The condom!''' We forgot the condom!" (capote means both hood and condom)
** '''The context:''' Fantasio and Spirou are sleeping in a castle ruin, two separate beds. They used pieces of tarpaulin to keep themselves from the rain, except the one above Fantasio suddenly ripped and unloaded buckets of water on him. He wakes up shouting "'''The hood!''' We forgot the hood!" (on the car, to protect it from rain)
* JumpingTheShark: For some "Machine qui rêve" is where the DarkerAndEdgier trend went way too far [[ArsonMurderAndJaywalking and Seccotine's true name revealed as Sophie.]] It was supposed to be the beginning of of a new era but the negative reception stopped Tome and Janry for writing another book. Another candidate is [[ContinuityPorn "Aux sources du Z"]] where [[spoiler: [[MindScrew Spirou settles down with a previous antagonist and gives to Fantasio his past self to live another adventures]] ]]. Then again it was the last book from the duo Morvan and Munuera.
* MyRealDaddy: Creator/AndreFranquin is often seen as the creator of the series rather than Rob-Vel.
* TheProblemWithLicensedGames: The NintendoHard MegaDrive[=/=]SuperNES game, reviewed by [[http://www.joueurdugrenier.fr/spirou-megadrive-2/ the Attic Gamer.]]
* VillainDecay
** Zorglub, even before his HeelFaceTurn. Also the whole point of ''Le Réveil du Z'', where Zorglub's successor only manages to recreate TheThemeParkVersion of the original's vision.
** Let's not forget Vito "La Déveine" Cortizone, a powerful mafia don who eventually is somehow deported through the little rural town of Champignac with nearly no security.
** The Triangle went from "globe-spanning barely competent criminal organisation" in ''Du Glucose for Noémie'' to "half a dozen idiots who can't even operate their secret lair's traps correctly" in ''L'Abbaye Truquée'', mainly because they lost most of their competent members in previously failed operations told between ''Glucose'' and ''Abbaye''.
