These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Carlisle, from the little we see of him gives off this vibe, dissecting children while still alive in order to understand how they can use magic and to provide his family with superpowers, and starting a plague for no reason other then he can. Richard also gives this off, doubling as The Caligula. So much so, he manages to shock members of The Authority so much they rethink their own actions and step down from power (!).
Twilight VII: The Dog Bites Back/The Gathering Storm/The Dark Tower
Anti-Climax Boss: Discussed but ultimately averted. The Crimson King is killed offscreen before he can finally be confronted, by The Saint of Killers, but he is fought instead and actually makes a better villain, as he planned to climb the staircase and kill GOD. And Stephanie Meyer, with her formidable reality bending powers, is more a threat then she appears. Even if she does just drool and shout out "EEEE!"
Big Lipped Alligator Moment: Ivenzo/Zexion confronts Leon and reveals himself to be Doctor Insano in one post only for the events to be totally ignored in his player's next post because they were considered too insane even for this game.
Can't be listed here, for fear of crashing the entire internet. But most characters get at least one.
However, Elijah Snow's Karaoke gambit is a particularly fine example.
Crowning Moment of Funny: Death and Thanos are spending time together, now that he's dead again. So Thanos, on the advice of Morpheus, creates a copy of The Little Mermaid by manipulating his cells to into the shape and cellular structure of a DVD to watch with her as a sort of date. We are then treated to an explanation of Thanos the nihlist trying to make sense of it.
Trapped by Mountain Lions: Some of the subplots seem to have little to do with the premise of the game, though they are eventually drawn together somewhat satisfactorily.
