History DeusExMachina / AnimeAndManga

** By the end of the Deicide arc, Aizen had become so powerful that it took several consecutive dei ex machinis to take him down. After Aizen curb-stomped everyone in his way and developed the ability to heal from any wound, Isshin takes Ichigo to teach him a never-before foreshadowed technique that channels all his spiritual into his physical strength, leaving Aizen completely helpless against him. When that's not enough, the Hogyoku spontaneously rejects Aizen, and then it's revealed that Kisuke implanted a special kido into Aizen that would seal him if that exact scenario happened.

* In ''Manga/{{Naruto}}''

* ''Anime/{{Scryed}}'' has an episode in which Ayase is battling Kazuma. While fighting, she has a heart monitor reading her brother's life signs. However, when her bro kicks the bucket, she throws the fight and somehow ''loses the will to live'' and just dies.

** After spending the last thirty chapters wreaking havoc Nagato pulls a case of RedemptionEqualsDeath and a device that was only shown to be able to repair corpses to bring back [[DeathIsCheap everyone]] that he had killed since entering the village.
** During his assault on the Kage Summit, Sasuke nearly died from chakra exhaustion, having been spamming the crap out of high level techs with his new Mangekyo Sharingan. And then, out of nowhere, Zetsu, who had previously shown up to alert the Kages to Sasuke's presence and gotten killed for his efforts, reveals that he managed to use a time release jutsu in the split second before the Raikage snapped his neck that sucks all the chakra out of everyone in the room and gives it to Sasuke.

** Kabuto pull a HeelFaceTurn, and helping to revive Sasuke. The reason? [[HandWave His time in Itachi's Izanami spell helped Kabuto realize his true nature, that he's really a good person deep down, and that he has a home to return to]].
** [[spoiler: Obito died, but turns out his eyes have the power to teleport the user from the afterlife back to the land of living as a chakra ghost, and then he passes both his Sharingan to Kakashi ''using chakra transfer''. Mind you the Sharingan is a [[SuperpowerfulGenetics bloodline limit]] and his physical eyes were both destroyed when Kaguya desintegrated his body. And then Kakashi fully manifests a Susanoo [[InstantExpert in its stabilised perfect form in the first try]]. This isn't even getting started on the fact that Kakashi is able to use the Uchiha bloodline technique Susanoo, despite the fact that he, you know, ''isn't an Uchiha''.]]

** [[Manga/JoJosBizarreAdventureBattleTendency Part 2]] eventually has the BigBad Kars becomes ''immortal'', being able to survive being roasted alive in a volcano and being able to curb stomp the good guys. Joseph admits his defeat as the battle is truly hopeless and he's run out of plans... then Kars's finishing move, a Hamon strike that he suddenly gained the ability to use, gets bounced and amplified by the [[McGuffin Red Stone of Aja]], creating a giant volcanic eruption and along with other things being tossed that launch him into the outer space, where he is ultimately frozen alive and floating around the universe for eternity.

* [[Anime/TengenToppaGurrenLagann Gurren Lagann]] did this over and over... sort of. Essentially a "logical" Deus Ex Machina was set up for the show's entirety with Spiral Energy, literally giving characters the ability to do the impossible ([[spoiler:the chance of Kittan's giga-drill that freed the crew from the spiral-draining sea thing succeeding was given as 0% but through a great speech and shouting he succeeded]]) through their sheer willpower and greatness. On paper it sounds like an extreme Deus Ex Machina, but when watching/reading it [[RuleOfCool it's awesome]] and used enough to not feel like the giant cop out it may first appear. Gainax being Gainax, they then hang a lampshade in the last act of the anime that is summated "using Spiral Energy too much will destroy the universe" (read: "using this too often can ruin a series").

* Played absolutely straight in ''LightNovel/{{Slayers}} NEXT''. Nearly the entire plot revolves around Lina's [[HoldingBackThePhlebotinum refusal to cast the Giga Slave]] after her discovery that miscasting it may end the world. Hellmaster Fibrizo eventually blackmails Lina into casting it and ensures that the casting fails, only for the power called upon by the spell, the supreme creator goddess of the Slayers universe, the Lord of Nightmares, to take Lina's body as an avatar instead and promptly annihilate the previously invincible (to the heroes) demon lord with a casual gesture. She also plays ResetButton by bringing everyone back to life that Fibrizo had killed (Lina's breaking point about casting the spell was his threat to [[DeaderThanDead obliterate their souls as well]]). The kicker: if Fibrizo hadn't ensured it would miscast, his plan would have worked and the wordl would have ended. However, because the power in question becomes present when the spell that calls for her help is cast, his attempt to force it backfiring was also a direct attack on the Lord of Nightmares herself. Summed up by Lina:

* ''Anime/SonicX'' has one of these in the finale of its final season, where the stone Cosmo has been wearing since the beginning of the series is revealed to be a magical amulet that can automatically accelerate her growth so that she reaches the stage of becoming a tree (as is apparently the fate of all her species) early, attaches herself to the bad guy and weaken him so that the Good Guys can shoot and destroy. We had heard nothing about this earlier in the series.

* In ''Manga/InitialD'', when Takumi battles the Todo School's rally driver with the School's demo car at Happogahara, he is absolutely going to lose [[spoiler:until a weasel jumps out in front of the Civic just before the final corner. When the driver swerves to miss it, Takumi passes, not seeing the cat because his lights were off.]]

** In ''Nobita's Little Space Battle'', the characters have been shrunk and the gadget they used to do so had been stolen, so they must take it back as it is the only way to reverse the shrinking effect - or wait for half a week, because apparently the effects of the shrink ray isn't permanent. Plenty of other times though it's been implied that it ''is'' everlasting. In fact, this is the only time that the effects of the shrink ray wear off in the show.

** Another one comes at the end of [[Manga/JoJosBizarreAdventureVentoAureo Part 5]], when Giorno fights Diavolo. Giorno is [[spoiler: pierced by the Requiem Arrow]], and his Stand Gold Experience gains the ability to [[spoiler: ''[[NoSell negate any action taken by an opponent.'']]]] Stands had been shown to develop new abilities thanks to the arrow before, but that power is ridiculously broken.

* ''Manga/DetectiveConan'', Conan can do ''anything'' at given times from riding a motor boat, a helicopter, and shooting guns with a common excuse of "My dad taught me that in Hawaii". The movies happen to be much more action oriented compared to the cases seen throughout the show where you'll only come across action related content during episodes/arcs related to the Black Organization. The good news though is that the Hawaii excuse is only ever used throughout the non-canon movies so in regards to Gosho Aoyama's manga, this copout doesn't overlap with the source material.

* ''Anime/{{Pokemon}}'':

** In Seasons 2 and 3, Marik's Millennium Rod likes showing Kaiba visions, since Kaiba owned the Rod in a past life. When Marik orders the Rod to show him those same visions, it doesn't obey him.

** In the last duel of the Battle City Final Yugi plays Ragnarok, a previously unseen card, which allows his entire cast of monsters to pulverize the Winged Dragon of Ra, and leaving Dark Magician and Dark Magician Girl on the field. The card was never played or mentioned again. [[RuleOfCool (But it was kick-ass awesome.)]]

** A major sticking point with fans at the end of [[JoJosBizarreAdventureStardustCrusaders Part 3]] is Jotaro's [[spoiler: spontaneous development of Time Stop]] in his fight with DIO, which enables Jotaro to fight DIO on more or less equal terms. The only possible foreshadowing of this is DIO's comment that he and Jotaro share a similar type of Stand, but DIO is just as shocked as the reader when Jotaro is able to [[spoiler:move during DIO's Time Stop]]. It's still not as ridiculous as in Part 5 [[spoiler:since DIO's vampire stamina allows him to stop time for longer than the human limit of five seconds while Jotaro struggled to move for even two to three seconds, meaning the latter was still at a ridiculous (but not hopeless) disadvantage.]]
