* ''Manga/MahouSenseiNegima'' has one hell of a wham episode when the Ala Alba are on a trip to the magical world. They arrive in the magical world, and it almost seems like a vacation... until the big bad shows up, stabs the hero through the chest, and beats the crap out of everyone. Then he scatters the entire team across the entire magical world, many into wilderness they're ill-equipped to survive. (Oh, and gets them blamed for his attack and hunted as wanted criminals.)
** Pretty much everything that happens for the first few times Kurt Godel is around. Let's see: reveals the identity of Negi's MissingMom and the fact that said MissingMom is widely (but falsely) believed to be responsible for a genocide, claims to be TheManBehindTheMan who's responsible for pretty much everything bad that's ever happened to Negi, and triggers Negi's SuperpoweredEvilSide, almost getting our beloved WideEyedIdealist to kill him in cold blood.
** In chapter 311, Chachamaru seemingly blows up Fate. But remember how Fate is the 3rd in the Averruncus series? Numbers 4,5, and 6 crash the party, and they make him look as gentle as Nodoka.
** Does anyone remember the first anime? The episode where Asuna '''drops dead''' counts. And the following episode, where it actually manages to [[FromBadToWorse get worse]]. [[DespairEventHorizon Much worse.]] They even dropped the [[MoodWhiplash cheerful intro]], just in case you hadn't caught on yet.
** [[spoiler:In chapter 329, Fate stops fighting and agrees to work with Negi. Then the [[SealedEvilInACan Lifemaker]] makes his entrance by shooting them both. Then in chapter 330, it's revealed that ALL of Cosmo Entelecheia has been revived... even the ones that died twenty years ago.]]
*** [[spoiler:And then Evangeline [[BigDamnHeroes arrives]]... And in the following chapters, it gets revealed that she brought the entire Ala Rubra as back-up]].
** In Chapter 334...Hey guys, ever wondered what happened to [[spoiler:Nagi Springfield]]? Well, guess who got [[spoiler:possessed by the Lifemaker]]...
** Chapter 352: [[spoiler:Asuna wakes up from her hundred-year sleep to find that she overslept for thirty years and Negi ''died'' somewhere in the intervening timespan, despite supposedly being immortal now.]]
