History YMMV / BlakeAndMortimer

* MoralEventHorizon: In ''The Art of War'', [[spoiler:Olrik crosses it by trapping Blake and Mortimer in an experimental remote controlled stealth bomber and sending it on a collision course with the newly built UN headquarters to start World War III with the intent of framing Blake and Mortimer as the worst traitors in history [[ForTheEvulz simply because he can]].]]

** ''The Atlantis Enigma'': [[ChronicBackstabbingDisorder Magon]] does not even consider the number of his compatriots who will die in his coup, and calmly considers the elimination of the Barbarians who helped him once they have lost any usefulness. And just as calmly plans to conquer the surface of Earth with another genocide as a result.

** It got an explicit mention in the text for the first time ever in ''The Last Swordfish'', when two patrons at the Centaur Club sneer at Blake and Mortimer's apparent intimacy and gossip maliciously that they are unmarried men living in the same house and are always together where ever they go. Later on, they are shocked when the pair bring Nasir to dinner at the club, revealing them as racists as well as homophobes.

* JerkassWoobie: [[ArchEnemy The colonel Olrik]], of all people, goes through a lot in ''The Septimus Wave''. Not having recovered from the late Septimus's brainwashing in ''Recap/TheYellowM'', he found refuge in Miss Sing's Chinese establishment, where only morphine injections prevent him from completely going insane. [[BigBadDuumvirate The four Big Bads]] and Mortimer's activities with two Telecephaloscopes (one of Septimus's machines) doesn't help him; he has visions of a horde of Septimus wanting him back, only increasing his mental instability. The main antagonists kidnap him with the intention of brainwashing him again. The aforementioned Septimus horde actually exists and wants to capture him at all costs, forcing him to make an alliance with Mortimer. Desperate to get rid of the {{Mind Rape}}s for good, Olrik even accepts to take over the Mega Wave to end the phenomenon, [[HeroicSacrifice despite risking to permanently lose his sanity on the process]]. In the end, he hasn't recovered from his experience and is reduced to repeating a MadnessMantra in Bedlam Hospice. Despite being the overarching villain of the series, Olrik's weaknesses are heavily present throughout the book, making him a surprisingly sympathetic character.

* HarsherInHindsight: ''Secret of the Swordfish'' is about Tibet conquering the whole world. It predates the historical Chinese annexion of Tibet by a few years.

* HoYay:
** Between Blake and Mortimer, who are usually living together. Over the course of the series, it becomes clear that they are by far the most important people in each other's lives. At one point, they are taken prisoners and sleep on the same bed.
** Lampshaded by two patrons at the Centaur Club who say that Blake and Mortimer are unmarried men living in the same house and are always together where ever they go.

* SpiritualAdaptation: ''The Curse of the Thirty Denarii'' is basically an unofficial adaptation of ''Film/RaidersOfTheLostArk''. A story located in the Mediterranean region? Check. A biblical artifact serving as MacGuffin? Check. The artifact is rumored of having supernatural powers? Check. The antagonists are a group of Nazi looking for said MacGuffin? Check. A submarine appears as a Deus Ex Machina in favor of the bad guys? Check. [[spoiler:The good guys are the first ones to find the artifact, then the villains stole it from then]]? Check. [[spoiler:The mystical power of the artifact kills the Nazi antagonists]]? Check.
* SpiritualSuccessor: To Hergé's Tintin adventure series. In fact Jacobs and Hergé were close acquaintances, and Hergé would often make a reference to Jacobs in his works.
