13[[SealedEvilInACan Sealed Evils in Cans]] of Anime and Manga.
14----
15* ''Manga/AhMyGoddess'' has the Lord of Terror, sealed away somewhere until Mara foolishly summons it. After much trouble, Skulk manages to trick him into [[BodySurf transferring itself onto a floppy disk]] and then breaks the writing notch, thus trapping it again... And then takes a magnet to it, promptly killing it while it's vulnerable before anyone can have the bright idea of repairing the notch.
16* ''Manga/{{Ajin}}'': This is the ultimate fate of [[spoiler:Satou. As he seemingly cannot be permanently killed and the world can't afford to simply let him age in a cell, knowing he'll come up with some way to escape, they cryogenically freeze him in an underground pod. It's noted that due to the technology, Satou won't age, which means he won't die of age within the pod, but the pod is self-sufficient enough to last for at least 200 years without shutting down]].
17* It’s revealed in Episode 24 of ''Manga/AkazukinChacha'' that Daimaou is unable to leave his castle because Chacha's grandfather, Genius, put a circle of crystals around it that shock him if he tries to pass them. This conveniently happens just as he's trying to kill his minion Sorges for continually failing him and learning his true nature, allowing Sorges to escape. The next episode reveals that this was an odd case of a double sealing, as Genius himself was sealed in the ruby in Chacha's medallion just after, which was snatched up by Seravy as he fled from Daimaou.
18* As discovered in ''Manga/AttackOnTitan'', [[spoiler:The Walls themselves are stuffed with dormant Colossal Type Titans. Following the Return to Shinganshina arc, their origins are finally revealed: It turns out that the people of the Walls are amnesiac refugees from the Marleyan Empire's attempted genocide of their people, the Eldians. The last king of Eldia and first King of the Walls, Karl Fritz, fled the mainland to Paradis Island with a contingent of Eldians, and used the Titan-controlling abilities of the Founding Titan to have several Colossal Titans crystallize themselves into the Walls, both as a defense against a potential invasion by the Marleyan Empire and as a seal to keep the largest surviving group of free Eldians away from the rest of the world. He then proceeded to brainwash his people into forgetting their history and threaten the countries outside of Paradis with complete and utter destruction if they ever dared set foot on the island. [[GambitPileup It's complex, to say the least...]]]]
19* Mag Mel[[spoiler:[=/=]Emperor Barodius]] and Razenoid[[spoiler:[=/=]Dharak]] started the fourth season of ''Anime/{{Bakugan}}'' as this. Credit must be given to [[spoiler:Code Eve]] for being ''extremely'' thorough though. He was sealed inside armor [[MadeOfEvil crafted from his own evil]], then imprisoned in an alternate universe, ''and'' tied to his own throne with powerful webbing. The only reason he was able to free himself was simply because he had a PsychicLink to [[TheHero Dan and Drago]], allowing himself to become powerful enough to free himself, something the one who put him there wasn't aware of.
20* The {{Hentai}} ''Bible Black'' features the titular Black Bible, a spell book that the protagonists have at some point used to conjure [[LovePotion love spells,]] and other minor hexes for fun and profit, but also features an incantation to summon demons via VirginSacrifice. One Character learned the hard way [[NaughtyTentacles what happens when you don't use a human sacrifice.]]
21* ''Manga/{{Bleach}}'':
22** Central 46 decide the only way to handle Aizen is to imprison him in their most secure prison. For 20,000 years. [[spoiler: His fusion with the Hougyoku cannot be undone and renders him almost unkillable. As a result, the only option is imprisonment. In the Final Arc, the GreaterScopeVillain mysteriously offers Aizen the opportunity to leave prison if he's willing to be recruited. Equally mysteriously, Aizen refuses, choosing to remain in prison. When he's finally released as part of a GodzillaThreshold to fight said villain, Aizen only agrees because he can't accept someone else taking over the cosmos, and when all is said and done willingly goes back into the prison despite the fact at that point there was no one left who would have had the available power or will to stop him if he decided otherwise.]]
23** The Quincies know of ancient folklore that speaks of a Sealed King. According to the legend, he would regain his heartbeat after 900 years, then his intellect after 90 years, followed by his power after 9 years. [[spoiler:A secret final stanza adds that he will then regain the world after 9 days. Mysteriously, he wanted Aizen on his side for this. Equally mysteriously, Aizen refuses.]]
24* ''Manga/DeadmanWonderland'':
25** The "evil" are people affected by the "Branch of Sin" [[spoiler:dangerous blood-manipulating powers]] who are secretly hidden deep in the "can", a maximum security prison/publicly open ''amusement park''. [[spoiler:Later {{subverted|Trope}} since it was revealed that many of them did not actually commit any crime, and were kept there solely for the study of their powers.]]
26** In an example played more straight, [[spoiler:Deadman Wonderland itself was actually originally built to imprison Shiro, the Wretched Egg, by keeping the majority of her powers sealed via the Mother Goose System. {{Justified|Trope}}, because as Makina points out, Shiro's regenerative abilities are so great that even the full extent of her own powers turned against her could not kill her. As such, the only way they could more or less stop her was to contain her, and she still broke free from time to time, like when she slaughtered everyone in Ganta's classroom at the start of the story.]]
27* ''Anime/DigimonFrontier'':
28** [[BigBad Lucemon]] was sealed away in the Digital World's core. [[spoiler: Some time later, he ends up using the Royal Knights to scan the entire Digital World and its three moons, effectively vaporizing them, to break free. ]]
29** This is what happens to [[spoiler:[[EldritchAbomination the D-Reaper]]]] at the end of ''Anime/DigimonTamers''. [[spoiler:Unable to truly kill it, the Tamers, in desperation, force it to regress to its earliest, most primitive form, and lock it in some other dimension.]]
30* Justified in ''Anime/DogDays''. Most demons are gods and spirits who have been corrupted, and the only way to turn them back is to seal them up and wait for the corruption to dissipate.
31* In ''Manga/DragonBall'', the original BigBad, Emperor Pilaf, uncorks Piccolo Daimaō ("Great Demon King Piccolo"), the Sealed Evil In a Can who had previously been trapped in a Denshi Jar by Mutaito-sama centuries before the start of the series. (The Denshi Jar gets bonus points for strangeness; it is, in fact, an electric rice cooker with a holy seal glued to it.) Naturally, he panics whenever someone intends to try to seal him in another Denshi Jar. Piccolo is revealed to be a Gnostic version of {{Satan}}, being the pure evil that the current God expelled to get "pure" enough to get his position in the first place (oh, and God is a SufficientlyAdvancedAlien). The trope is somewhat subverted, however, in that, one {{reincarnation}} and one HeelFaceTurn later, Piccolo joins the good guys. And eventually even [[FusionDance fuses with his "good" half]] when they desperately need a power boost. Interestingly enough though King Piccolo aged while he was in the rice cooker, so eventually he (or God and therefore him) would have died, making eventually a permanent solution.
32** Later, Kami/God, the good half of Piccolo, tries to use the spell to seal him again in a bottle, but Piccolo reflects the spell, traps Kami instead and eats the bottle, Kami is quickly released later.
33** Later, in ''Anime/DragonBallZ'', the five-million-year-old sorcerer Babidi comes to Earth seeking energy to power Buu, the Sealed Evil In a Can that ate King Kai's superiors (sort-of explaining why none of these guys ever bothered to stop Freeza).
34** Creator/AkiraToriyama acknowledges his reliance on the Sealed Evil In a Can formula in the ''Neko Majin Z'' parody comic, in which the titular "hero" keeps a powerful demon sealed in a small rock balanced on top of a boulder by the side of a road. If anyone picks up the rock, the demon is released, requiring Neko Majin to step in and re-seal the demon... for a fee.
35** In the first ''DBZ'' movie, ''[[Anime/DragonBallZDeadZone Dead Zone]]'', Kami reveals that a rival he competed with while becoming Earth’s God named Garlic became so angered that he was not chosen that he attempted to take the title by force. Kami responded by sealing Garlic in the titular Dead Zone. Uniquely, Garlic is still stuck there- it’s his son Garlic Jr. that serves as the movie’s villain. Come the end of the film, Garlic Jr is sent into the Dead Zone as well, escaping for a FillerArc in the series and being sent right back inside at the end of it.
36** In the ninth movie, ''[[Anime/DragonBallZBojackUnbound Bojack Unbound]]'', the titular BigBad Bojack was sealed inside a star by the four Kais along with his Galaxy Soldier followers and presumably would have remained there for all eternity. But due to North Kai's death by Goku's sacrifice with ready-to-explode Cell, Bojack was freed from his imprisonment and headed towards Earth where Cell fought.
37** In the thirteenth movie, ''[[Anime/DragonBallZWrathOfTheDragon Wrath of the Dragon]]'', the monster Hirudegarn is split in two and [[SealedInsideAPersonShapedCan sealed inside Tapion and Minosha]]. Hoi breaks him free and rejoins the two halves... [[spoiler: You guessed it, Hirudegarn stomps on Hoi and kills him. And Hirudegarn is eventually killed by Goku (who at that point used a technique that could have defeated it right from the start).]]
38** In ''Anime/DragonBallSuper'', the Denshi Jar is again [[spoiler:attempted]] with Zamasu.
39* [[spoiler:Liselotte Werckmeister]] in ''VisualNovel/ElevenEyes'' was sealed by the Black Knights in a Crystal as she is an immortal and intends to destroy the world. Though in the finale of the story, the seal is undone. In the anime only ending, once again she is sealed away to a spacetime rift with Kakeru and the black knights combine effort. In the original game novel, [[spoiler:Kakeru manages to finally [[KilledOffForReal kill her off for good]] by destroying the Voidstone within Liselotte using the Eye of Aeon]].
40* The character Isaac from ''Manga/EternalSabbath'' was sealed in a glass tank for several years before breaking free and wreaking havoc using his [[PsychicPowers charm and charisma]].
41* [[spoiler:Zeref]] of ''Manga/FairyTail'' is revealed to be this right after someone wastes their life trying to raise him from the dead.
42** Even worse, the guy who wasted his life was just a diversion while someone else got the keys to unseal [[spoiler:Zeref, who reveals later that he was ''never even sealed''. He also isn't really that evil in the present.]]
43** The most powerful [[OurDemonsAreDifferent demon]] of the Dark Guild [[LegionsOfHell Tartaros]], [[NamesToRunAwayFromReallyFast Master E.N.D.]], is trapped within his [[TomeOfEldritchLore Book of Zeref]] and can only be freed if enough "curse power" is gathered together, around which the events of the eponymous arc were all about doing, [[spoiler:or if Natsu himself opens it.]] This is because E.N.D. [[spoiler:really stands for '''E'''therious '''N'''atsu '''D'''ragneel]], though it's not made clear if the book actually contains the demon himself [[spoiler:or simply his powers and memory]].
44** {{Subverted}} with [[spoiler:Deliora]], the demon that was sealed by [[spoiler:Gray's teacher, Ur, who gave her life to trap it with Iced Shell]]. It was a sealed evil in a can, but it turns out that its power was drained so much from being sealed that by the time it's finally set free, it's already seconds away from death, [[spoiler:and then gets completely destroyed with just one punch]].
45* ''Manga/FrierenBeyondJourneysEnd'' has the demon Qual, who was so powerful that Frieren had to seal him away because her party weren't strong enough to defeat him. Eighty years later, the seal is about to fail, so Frieren returns with her apprentice Fern and removes the seal herself. As it turns out, during the time Qual was sealed, humanity had been studying his magic and incorporating it into their own techniques; [[VillainForgotToLevelGrind his previously-unblockable Zoltraak spell now bounces harmlessly off Fern's magic shields, and Frieren kills him in one blow]].
46* The ghosts of ''Anime/GhostStories'', until the construction sites destroy the places where they had been imprisoned. Satsuki then has to spend the rest of the series re-sealing them.
47* ''Animation/GuardianFairyMichel'' has the evil pharaoh, Lucifer, in episode 23. Salome accidentally unseals him while hunting for treasure.
48* The Phantom Empire of ''Anime/HappinessChargePrettyCure'' was trapped inside the Axia Box... [[spoiler:then a young Hime opened the box.]]
49* ''Manga/{{Hellsing}}'':
50** In the Gonzo version, the final episode reveals that Incognito plans to [[spoiler: release the Egyptian god Set in order to]] destroy the world. [[spoiler: Alucard defeats the released Set, it is left ambiguous if Set was really destroyed or just resealed]].
51** Alucard himself used to be in a state of hibernation as a dead, rotting husk in a basement. And then ''someone'' found a way to splatter him with ''blood''...
52* ''Manga/HellTeacherNube'' has a demon who tried to kill him in his childhood sealed into his left hand by his [[TheMentor mentor Minako]].
53* ''Manga/{{Inuyasha}}'':
54** Inuyasha is a half-demon who was sealed to a tree by the priestess Kikyo's arrow for 50 years, until Kikyo's reincarnation Kagome freed him out of necessity. [[JerkWithAHeartOfGold His apparent "evilness"]] [[HeelFaceTurn didn't last long]].
55** The seal is played straight with Ryuukossei, however. The powerful youkai that killed Inuyasha's father is first mentioned only when it becomes necessary for Inuyasha to succeed in an achievement that surpasses his father so he can master his sword. Cue introduction of Ryuukossei who had never been mentioned prior to that point. Reason being that Inuyasha's father managed to seal Ryuukossei with a fang the way Kikyou had sealed Inuyasha with an arrow. Naraku frees Ryuukossei who fights Inuyasha and dies, allowing Inuyasha to surpass his father and master his sword.
56** The Shikon no Tama. Unique in that it is both Sealed Evil In A Can ''and'' SealedGoodInACan. It contains the spirits of many demons that were once one entity and a powerful priestess locked in battle, making this actually a case of SealedEvilInADuel.
57** An anime-only example happens when the cast actually tries to seal away something evil to create this trope. When [[EvilWeapon Toukijin's]] creator is killed as a result of the sword possessing him, the sword lands in the middle of a field. Even UltimateBlacksmith Toutousai is unable to approach its immensely powerful evil aura, leaving them at a loss what to do. In the manga, this is the moment where Sesshoumaru (who commissioned the creation of the sword) arrives, defeating and mastering the sword as soon as he touches it. In an AdaptationExpansion, the [[{{Filler}} anime]], has the blade begin to corrupt the ground around it as soon as it lands, spreading swiftly. Since none of them can approach it, they debate what to do and Miroku decides to build a small shrine around the sword, blessing it to keep Toukijin's evil from spreading. Only then does the anime allow Sesshomaru to arrive to defeat and master the sword.
58** In the third movie ''[[Anime/InuyashaTheMovieSwordsOfAnHonorableRuler Swords Of An Honorable Ruler]]'', the evil sword Sou'unga was also sealed away for a few hundred years, only to break the seal while in Kagome's time and go about trying to kill everyone.
59* ''Manga/JojosBizarreAdventure'':
60** In ''Manga/JojosBizarreAdventureBattleTendency'', there are the Pillar Men, powerful vampires that were trapped in stone and left inside of ancient temples until they were freed.
61** In the third part of the series, ''Manga/JojosBizarreAdventureStardustCrusaders'', Dio Brando is released from imprisonment in a casket at the bottom of the sea by some unwitting seamen, where he'd spent the last 100 years since the end of [[Manga/JojosBizarreAdventurePhantomBlood part one]].
62* In ''Manga/KamichamaKarin'', the BigBad sealed himself inside the ring of Zeus. [[spoiler: In the anime, it's implied that [[BigGood Kujyou Kazuto]] [[SealedGoodInACan sealed himself or part of himself]] in the ring he gave Micchi, so he'd be able to help if/when Karasuma awakened.]]
63%%* ''Literature/KyoKaraMaoh'': Soushu is Sealed Evil in [[FourIsDeath four]] Boxes.
64* ''Anime/MagicalGirlLyricalNanohaAs'': The Book of Darkness regenerates every ten years, sealing its programs (the Wolkenritter) inside of itself until then. Also, [[spoiler:Gil Graham plots against both the heroes and Wolkenritter to allow for the Book, Wolkenritter and their [[TheKidWithTheRemoteControl innocent mistress]] to be sealed in the space between dimensions forever, because the Book would just keep regenerating. He is stopped and regrets ever deciding to put these lives at risk.]]
65* ''Manga/MagilumiereCoLtd'': Once a Kaii's health is low enough, a magical girl can use a spell that sucks it inside a small flash drive where it can no longer wreak any havoc.
66%%* ''Manga/MermaidMelodyPichiPichiPitch'': The Panthalassa and the real Michel.
67%%* ''Anime/MonsterRancher'': Moo's draconic body is sealed away in ice. Finding it is one of his major goals.%%That's the "Sealed" part. What about the Evil?
68* ''Anime/Moomin1990'': In "The Imp", Moomin and his friends come upon a dead tree which has a malicious demon (though he's called an imp in the English dub) contained within. He pretends to have [[EvilRedeemedInACan turned good during his imprisonment]], and to prove it, he promises to grant the children wishes in exchange for releasing him. With everyone but Moomin falling for the ruse, they place a straw in the trunk, allowing the demon to get out through it in a smoky form. He then gloats that he has remained as evil as ever and intends to turn the children into animals. Snufkin saves them by tricking the demon to return inside the tree and removes the straw, trapping him there. The tree is then taken to drift in the sea.
69* The plot of ''Manga/MyBalls'' has been summed up as "sealed evil in a man-can." Naturally, [[CantHaveSexEver sex will let it out]], and [[ColdTurkeysAreEverywhere there are just so many temptations]]...
70* Tailed Beasts in ''Manga/{{Naruto}}'' are generally SealedInsideAPersonShapedCan because it lets people use their power, there are a couple cases where they've been sealed inside objects: Shukaku was said to have been sealed in a teapot, the 8-tails was sealed in a giant jar (which can seal people in it as well), and [[spoiler:after removing the Ten Tails chakra the Sage of the Six Paths sealed it in stone and put it in the sky, creating the moon.]]
71** [[spoiler: After acquiring chakra material of all 9 Tailed Beasts, Tobi/Obito uses the Demonic Statue of the Outer Path as a vessel for its resurrection.]]
72** This is later subverted, as [[spoiler:it's revealed that the tailed beasts aren't inherently evil, it's just that most of them hate humans due to (repeatedly) being used by them throughout history. Killer B, and later on Naruto, eventually get the beasts sealed in them to make a HeelFaceTurn by actually respecting them as sentient beings rather than treating them like mindless monsters.]]
73** [[spoiler:It turns out the Ten-Tails wasn't evil at first either. It didn't even have a mind of its own since it was a tree. The Sage and his brother sealed their mother Kaguya inside the God Tree since her power had driven her mad. This only partly worked, since Kaguya ''fused'' with the God Tree and transformed it into the Ten-Tails to take her sons' chakra. That's when the Sage and his brother sealed the Ten-Tails, not realizing that their mother was the one controlling it.]] This is a weird case of one sealed evil in a can turning its ''can'' evil, making it necessary to seal the can too.
74* ''Manga/NegimaMagisterNegiMagi'': features three examples, two completely straight and the other a little bizarre.
75** Ryomen Sukuna no Kami is a gigantic four-armed two-faced demon god sealed in the Kansai region of Japan; releasing and controlling him was the motivation for the villains of the Kyoto arc.
76** [[spoiler: The Lifemaker, the ultimate BigBad of the setting,]] is sealed [[spoiler:inside the Sacred Tree of Mahora Academy.]]
77** The more unusual example is the ancient and legendary vampire sorceress Evangeline A.K. [=McDowell=]. While she ''was'' a wanted magical criminal, responsible for multiple heinous crimes and with a huge bounty on her head, her sealing was based less on her evil and more on her [[StalkerWithACrush obsession with the main character's father]], who made sure she would NOT get out of a certain BoardingSchool. And, once you get to know her, she's not really [[NobleDemon as evil as she liked to claim]]... to the point that when the aforementioned demon god is released, the protagonists defeat it by breaking the seal on Evangeline and letting her [[CurbStompBattle deal with it]].
78* In the backstory of ''Anime/NeonGenesisEvangelion'', Adam was automatically sealed by the Lance of Longinus when he first landed on Earth to prevent him from endangering the children of Lilith (humanity). [[NiceJobBreakingItHero Then a bunch of curious humans removed the Lance.]]
79* ''Manga/OnePiece'':
80** [[TheAlcatraz Impel Down]], the world's most secure prison has a level that most people don't even know exists, Level 6 the "Eternal Hell" which contains at least two ex-Warlords of the Sea, [[spoiler: former BigBad Sir Crocodile and Jinbe]], [[spoiler:Luffy's brother and Whitebeard Division leader Ace]], and Shiryu, the insane ex-Head Jailer who was a match even for Warden Magellan. And with the exception of [[spoiler:Ace]], all of these and more are free thanks to Luffy and Blackbeard.
81** [[spoiler: Caribou, sealed evil in a barrel.]] Poor mermaids.
82* After "Him" in ''Anime/PowerpuffGirlsZ'' is defeated horribly by [[MagicalGirl a bunch of girls]], he is contained in a tomb in an abandoned museum until the present day, at which point he sends out a mummy to find the means to release him from his prison. His main goal is to conquer the world and destroy the Powerpuff Girls for their resemblance to the Ōedo Chakichaki Musume, the first three to defeat him.
83* The anime version of ''Manga/{{Pretear}}'' starts with [[DarkMagicalGirl the villain]] breaking free after sixteen years of being sealed away. And in the manga version, she ''remains'' sealed--but still manages to [[DemonicPossession possess others]] anyway. [[spoiler: Specially true in the case of Himeno's stepmom Natsue, her main "host".]]
84* Generally, most ''Anime/PrettyCure'' villains don’t follow this rule, as they’re usually simply plotting from their base most of the time. The sole exception is ''Anime/HappinessChargePrettyCure'', where the villainous faction, the Phantom Empire, starts the season sealed inside of an Axia Box. However, they don’t stay in there for long, as Hime finds the box, gets a little too curious, and opens it, freeing them.
85* In ''Anime/PrincessTutu'' the evil raven was sealed away by a prince who broke his heart into shards; the raven gradually gains power through the series and is fully freed when the prince's heart is returned to him.
86* ''Anime/SailorMoon'':
87** Most of the villains were sealed until recently, except for the last season. In the first season, inside the can (the Dark Kingdom/Negaverse) was ''another'' can, with another, bigger Sealed Evil (Metallia/Negaforce) inside it; the forces of the Dark Kingdom spent most of their time draining energy from people in order to charge the metaphorical can opener needed to release her.
88** After one too many failures, Queen Beryl did this to Jadeite and sealed him in a crystal, never to be freed.
89** In the last season (in the anime at least), it is revealed that [[spoiler:at the end of the first Sailor War, Sailor Galaxia had sealed Chaos inside her own body, and sent away her own Star Seed (which would become Chibi Chibi) in hopes to not have it corrupted.]]
90* Poseidon from ''Manga/SaintSeiya'', sealed in a jar. ''Literally''. He manages to employ GrandTheftMe on a boy named Julian Solo, and through Julian he gathers the Marine Generals in hopes of defeating Athena and her Saints so he can properly get out. [[spoiler: He not only fails, but is ''again'' sealed.]]
91* ''Anime/SDGundamForce'' gives us Musha Daishinshou. A semi-sentient HumongousMecha, Dashinshou was sealed in Tenchijou because only a Daishogun could control his power. Otherwise, he would go on a rampage. Kibaomaru is believes he can control Daishinshou, and is looking for the key to entering him; Genkimaru, who can create portals.
92* ''Literature/{{Slayers}}'' has Ruby-Eye Shabranigdo, which was broken into seven pieces and sealed in humans (and gets out every now and then), Zanafar, and for good measure Shabranigdo's lieutenant Chaos Dragon Gaav.
93* In ''Manga/SoulEater'', the SealedEvilInACan is the Kishin, an insane creature who wreaked havoc upon the world until being sealed. The people working for the Shinigami do so to prevent the creation of another Kishin, which would occur if someone consumed a large number of human souls.
94** It is not until half-way through the series that the main characters discover that the "original" Kishin is still alive, and imprisoned underneath their city. [[BodyHorror In a bag made out of his own skin]].
95** At the end of the manga, the Kishin is left as [[spoiler: Sealed Evil ''[[WeirdMoon on the Moon]]'' by [[FromNobodyToNightmare Chrona.]] Hir method of doing so leaves the both of them, plus the moon, in a giant bubble of black blood.]]
96** The manga later reveals that there are [[EldritchAbomination similar]] creatures trapped elsewhere, although the Great Old One in Eibon's book has more in common with Shinigami than their estranged comrade Asura.
97* The 3 big bad Tayutai in ''VisualNovel/{{Tayutama}}'' are strong, but their method of sealing might have needed to be reinforced. They were freed by a runaway moped. On the other hand, it let [[SealedGoodInACan Mashiro]] out into the world, so it all balances out.
98* Ryoko, from ''Anime/TenchiMuyo'', was sealed away as a traditional demon in the {{OVA}}s; however, after calming down by dueling Tenchi for an episode, she joined the cast as a protagonist and suitor for Tenchi's hand. Washuu was in a similar situation in the TV series.
99* Near the end of ''Manga/{{Toriko}}'', [[spoiler: we find out Acacia has been using [[SealedInsideAPersonShapedCan himself as a vessel]] to keep NEO from running rampant and consuming everything. He does this, along with fostering enough hate towards himself to get Toriko, Starjun, and Midora strong enough to kill him and defeat NEO, as NEO's influence turns him into a monster.]]
100* The Decepticon army that Crosswise was jailer of in ''Anime/TransformersCybertron'', until [[TheStarscream Starscream]] freed them.
101* ''Anime/TheUltraman'' has a monster made of sentient purple gunk capable of taking over machinery, where it's sealed deep in the Himalayas until a human construction project released it from it's subterranean prison - the first thing it did which is to take over the kaiju-sized construction supermachine, Hectore, assimilatin gthrough it's systems and going on a ConstructionVehicleRampage.
102* In ''Anime/UmiMonogatari'', Sedna was sealed away in the sea and on land.
103* In ''VisualNovel/UminekoWhenTheyCry'', Beatrice; The Golden Witch, The Endless Witch, The Witch Who Has Lived For A Thousand Years; is set up as this. [[spoiler:However, the longer the story goes on, the less that seems to actually be the case]]. According to her the can she was sealed in was originally meant to seal something else. [[spoiler:This is also most likely not the case.]]
104* In ''VideoGame/{{Utawarerumono}}'', Hakuoro finally has his SugarWiki/MomentOfAwesome and has the BigBad Sealed In A Can. [[spoiler: Since he has to merge with his EvilTwin to do so, it counts as both SealedEvilInACan and SealedGoodInACan.]]
105* In ''Anime/YuGiOh'', Pharaoh Atem took the contingency plan of sealing both the BigBad and [[SealedGoodInACan himself]] 3000 years ago, until both resurfaced roughly simultaneously when their respective containers were found by archaeologists.
106** Despite his good intentions, [[KnightTemplar Atem's]] [[DemonicPossession less than polite hosting methods]] and [[DisproportionateRetribution outdated ideas of justice]] made ''him'' a close case of Sealed Evil In A Can in the early manga until Yugi got hold of [[TheKidWithTheLeash The Leash]] and convinced Atem to not do such stuff again.
107** In ''Anime/YuGiOhCapsuleMonsters'', Alexander's evil half was sealed in the pyramid while his good side was left in the Capsule Monsters world.
