History PyrrhicVictory / AnimeAndManga

* The end of ''Anime/CodeGeass'' goes something like this -- [[spoiler:Lelouch is dead, Suzaku had to fake his death (and both of their reputations are in ruins), the entire populations of both Tokyo and the Britannian capital are dead and it's likely that Nunnally and several others are likely to need some kind of therapy (which they apparently got by the epilogue). The world's at peace, but it's come at a heavy price]].

** The ending itself can be considered a MASSIVE one for Eren, [[spoiler: as even though he succeeds in ending the war and his efforts has the Power Of The Titans ultimately removed from the world (ensuring his friends can live long peaceful lives), it ultimately comes at the cost of his humanity as he ends up becoming the FinalBoss that wipes out 80% of humanity and he is unable to stay with his friends as he wanted, as he had to push them away so they won't get dragged down with him and have the strength to kill him, ultimately meeting his end at the hands of the woman he loved. And to add further insult to injury, while it ultimately takes centuries to reach that point (ensuring that his friends had long lived the lives Eren wanted them to have), Paradis Island is still destroyed by war and the story ends with a boy and his dog about to enter the now titanic tree Eren was buried under, strongly hinting that the Power Of The Titans will return. Basically, the only things Eren were able to accomplish that stuck was helping free Ymir (breaking the Curse of Ymir on Armin and the other Titan Shifters in the process) and giving his friends peaceful lives.]]

** '''Before''' the War began, Straw Hat Luffy sneaks into Impel Down trying to free his brother Ace, and ignites an unprecedented prison riot. Blackbeard also attacks the prison at the same time to do some recruiting, and the ultimate result is a mass jailbreak of at least 240 prisoners escaping, those imprisoned in Level 6 being so dangerous that the World Government had to erase their existence.

** The fight with Raditz ends with a Pyrrhic victory for Piccolo. He succeeds in killing both the alien threat powerful enough to fight Earth's strongest warriors and his long-time enemy Son Goku, but in the process the alien's even meaner, stronger buddies are now coming to kill them all. Plus, the [[HeroicSacrifce circumstances]] behind how he was able to kill Goku leave him both [[VengeanceFeelsEmpty unsatisfied]] and [[AndThenWhat wondering what to do next with his life]] once the problem with the oncoming alien threat is handled.

** '''After''' the War, Whitebeard final words, which confirmed the existence of the One Piece, started a second Great Age of Piracy even wilder than the last, with the Marines being unable to respond because of their forces being severely understaffed due to the casualties they suffered. All this, along with the power vacuum Whitebeard's death created, turns the New World into a bloodbath as numerous big name pirates start fighting each other to take his old territories. Worse still, both Fleet Admiral Sengoku and Vice Admiral Garp choose to resign from the Marines because of the Government's decision to cover up the Level Six prison escapees. Following the promotion of Akainu to Fleet Admiral, Aokiji also leaves out of disgust, and over the two year Timeskip, Blackbeard is able to take Whitebeard's place after seizing much of Whitebeard's former territory.

** Enrico Pucci in [[Manga/JoJosBizarreAdventureStoneOcean Part 6]] [[spoiler:kills most of the heroes and obtains his vision of "heaven", if only for a moment... but then gets killed by Emporio (a mere child, no less) using Weather Report's Stand, and the world then gets the ResetButton, with the Joestars still being around (albeit without their memories) while he's no longer in the universe, having never been born]].
