Walking Spoiler / Anime & Manga

• 20th Century Boys has two examples, both of the Friends: Fukubei, a mostly unremarkable character whose only trope-worthy characteristics come after he's revealed as the Big Bad, and Katsumata, whose mere existence is a major plot reveal at the end of the story.
• The 100 Girlfriends Who Really, Really, Really, Really, Really Love You: Girlfriend #6 is Hahari Hanazono, whose daughter Hakari is one of Rentarou's first two girlfriends. Her introduction to the harem is what breaks any and all limitations as to what kind of girls are among Rentarou's soulmates; any age, any relationships with already existing girlfriends, and any previously antagonistic characters are fair game.
• Air: It's near impossible to talk about Misuzu without spoiling anything, namely her being the reincarnation of Kannabi no Mikoto, getting cursed to grow weaker whenever she gets attached to anyone, and especially her death at the very end.
• Amagami: Risa Kamizaki and Mika Makihara both are responsible for the rejection that figures largely into Junichi's backstory. The former tricks the latter thus causing Junichi to think he was Stood Up.
• Assassination Classroom:
  • Kaede Kayano. Literally every single piece of information related to her, including her name, has to be re-evaluated after the revelations pertaining to her occur.
  • Aguri Yukimura. The series is very careful to not reveal that she, the woman shown several times in Koro Sensei's past and the former teacher of Class-E, are the same person, and knowing her relationship with Koro-sensei (or rather his prior identity as the God of Death, which is also a humongous spoiler) completely changes one's perception of Koro Sensei and his motivations.
• Attack on Titan
  • The existence of the Titan Shifters, humans with a Lovecraftian Superpower that allows them to create and pilot a Titan form. As a result, there's quite a few characters (Eren, Annie, Reiner, Bertolt, and Ymir) with entries that are largely spoilers. Especially Eren, as the last time we saw him before he showed off his Titan-Shifting powers, he was eaten by a Titan and was made to look like the Decoy Protagonist.
  • The Beast Titan, a strange ape-like Titan of incredible intelligence that can speak human language fluently and command other Titans. It is all but explicitly stated to have transformed the missing residents of Connie's village into Titans. He later turns out to be another Titan Shifter whose human identity- Eren's half-brother Zeke- is impossible to discuss without spoiling several plot twists.
  • The Colossal Titans entombed within the Walls, which appear to provide the foundations.
  • Anything related to the histories of the Empire of Eldia and the Kingdom of Marley, as well as any information regarding the Island of Paradis, the first and third ones contain massive revelations about the history of the world, the origins of the Titans and the main setting, the second spoils the biggest Plot Twist of the series - contrary to what the viewers thought for over 80 chapters, there is human civilization outside the walls.
  • The Yeagerist faction. The fact that an extremist group is named after the protagonist of the series spoils Eren's darker turn after the Time Skip.
• Bakuman。: Nanamine initially presents himself as a cheerful and energetic, if somewhat naive, young mangaka. Within a few chapters, you realize that he's actually a devious schemer who intends to subvert the editorial process and climb to the top of the manga world with online helpers, and it's difficult to talk about him without mentioning this.
• Berserk: The Idea of Evil, to the point the author originally omitted the original scene because he felt it was too much of a spoiler at too early a time.
• Black Clover:
  • The Word Devil Zagred's existence reveals that he was the true mastermind of the elf massacre, not the human royals whom he had lied to, and the one who reincarnated the elves, not Licht.
  • It's hard to talk about Nero in detail without revealing her true identity as Secre Swallowtail, a servant of the First Wizard King who has been watching over Asta all this time to prevent the plans of the devil who orchestrated the elf massacre.
  • Nacht Faust's existence reveals that the Black Bulls have an inside man in the Spade Kingdom and a Vice Captain, like all the other squads, who's also a devil host at that.
  • It's hard to talk about Licita without mentioning that she's the adoptive mother of Liebe, the devil in Asta's grimoire, and Asta's mother.
  • Lucius Zogratis. The very existence of a fourth Zogratis isn't revealed until 75 chapters after the Dark Triad are formally introduced. Then we learn that the fourth Zogratis, Lucius Zogratis, is the second soul of the Wizard King Julius Novachrono right before the beginning of the final arc.
• Bleach:
  • Royd Lloyd's existence is kept a secret until it is revealed that he was posing as Yhwach while fighting Yamamoto, and it's impossible to mention any of Royd's actions without spoiling that Yhwach was not the one who fought against and lost to Yamamoto. Even his name is a spoiler.
  • Kanae Katagiri is Uryuu's Missing Mom, but she isn't revealed until the final arc because her story is the key to the resolution of the plot; it connects Ryuuken's refusal to be a Quincy with the following: his estrangement from Uryuu, Masaki's death, Ichigo's origins and, above all, it contains the secret that leads to the defeat of Yhwach.
  • Merely the name Yachiru Unohana is this, since while it had been established some time before that Kenpachi Zaraki had named the little girl he adopted after someone important to him, finding out just who this person really is does a complete 180 on the previous characterization of Captain Retsu Unohana, who before had been portrayed as the kindly Team Mom of the Gotei 13 (although people are afraid to get on her bad side) but is in fact the previous Kenpachi and an Ax-Crazy former criminal.
• Blood+: Diva is Saya's twin sister and the series' Big Bad. She also does not make an on-screen appearance until the end of Episode 23, and her identity is not fully revealed until Episode 24. This pretty much makes her name the only thing you can mention about her without spoiling the entire first half of the series.
• Bloom Into You: Haru, who's only mentioned in the final chapter of the manga, and is a character in the spinoff novels, is Sayaka's girlfriend. It's impossible to mention the latter fact without spoiling that Touko rejects Sayaka's Love Confession.
• Bodacious Space Pirates: Ironbeard, captain of the Parabellum, during the last arc of the anime. He turns out to be Marika's father, who was stated to have died at the beginning of the anime and the reason Marika had to become captain of the Bentemaru in the first place.
• Bokurano:
  • Youko Machi, since she's from another Earth, is Koyemshi's sister (which in turn reveals that he used to be human), and planned for the kids to get involved in the game from the very beginning. It's difficult to talk about her without mentioning any of this.
  • Junji "Katari" Karita appears in one scene, falsely claims to be a Zearth pilot (thus derailing the plan to go public about Zearth) and is killed shortly thereafter. Essentially, his name and gender are all you can reveal without spoiling this.
• The anime adaptation of The Caligula Effect has Shingo Tachibana, the person who Ritsu based his appearance in Mobius off of. He doesn't appear until the very end of Episode 10 (at which point the audience is led to believe he's still Ritsu) and his relationship with Ritsu, as well as both of their involvement in the overall plot, isn't explained until Episode 11 (the penultimate episode).
• Case Closed: In episode 11, Narumi Asai, the kindly and seemingly innocuous female doctor who helped out Conan, Kogoro and Ran during their stay in Tsukikage Island turned out to be a man who cross-dressed as a disguise to enable him to investigate the suspicious death of his father and plot his revenge against the culprits. He was also notable to be the only murderer of the week who was Driven to Suicide after Conan exposed him, contributing greatly to his Character Development and he would later consider his failure to prevent Asai from committing suicide as his greatest blunder.
• Casshern Sins: Luna.
• Chobits: Mentioning pretty much anything about Freya will spoil major plot-points; namely, that she is Chii's older sister who had an emotional breakdown and became absorbed into Chii herself, leading to the latter's amnesiac state.
• CLANNAD: Ushio Okazaki. Her existence as Nagisa and Tomoya's daughter doesn't spoil the fact that the two of them ultimately get together, as it's made more than clear from the beginning that Nagisa is the main girl, but the fact that she's an actual character in her own right does spoil the fact that the anime continues on after they graduate to follow their married life. Her backstory also spoils the relatively well-known fact that Nagisa dies in childbirth.
• Code Geass: Lelouch's supposed-to-be-dead mother Marianne (whose spirit has been hiding in Anya).
  • Likewise, it's near-impossible to talk of Lelouch's half-sister Euphemia without mentioning her tragic end near the close of R1.
• Concrete Revolutio: Choujin Gensou:
  • Once a certain group photo starts getting passed around, prepare for the inevitable spoilers that the brunette on the left of it is Jin Nakagawa, who not only is Jirou's childhood friend but is Sword Phantom Claude. Nakagawa also helps Kikko out with suppression of her dark side, spoiling the fact that Kikko is in need of a husband so she can be a devil queen.
  • When an evil Hyouma shows up, it spoils the fact Hyouma is a time traveller who tries to change the past.
• Daily Lives of High School Boys: Habara may look utter unremarkable (she's the Distaff Counterpart of the local Ridiculously Average Guy Tadakuni), but she has very significant Backstory which cause most tropes under her—as well as her Red Baron during the time—to be spoilered.
• Danganronpa 3: The End of Hope's Peak High School:
  • Miaya is hard to talk without revealing that Monaca killed and replaced her and came into the game as a robotic avatar of her. Monaca is also this as well since she was not the mastermind of the final killing game.
  • As for Tengan aka the actual Big Bad of the anime, one can only expect him to be this.
  • The fact that Chisa is a Remnant of Despair throws her characterization into a loop.
  • Ryota was originally a downplayed version of this trope since his role was changed when the fans learn that Enoshima used his anime to get the Remnants of Despair on her side. Then, there's his role in Side: Hope...
• Death Note: Mello and Near; the fact they're L's successors (coupled with L's utter refusal to give up on the Kira case) are an easy tip-off to the fact that L dies.
• Demon Slayer: Kimetsu no Yaiba
  • Gyutaro, Daki's older brother and the stronger half of the duo, is only revealed midway through the climactic battle of the Red Light District arc.
  • It's difficult to talk about Akaza without mentioning that shortly after his debut, he kills Kyojuro Rengoku, one of the Hashira and the Arc Hero of the Mugen Train arc, or that his backstory is more tragic than people might have assumed.
  • Upper Rank 1: Kokushibo is a heavy example. Nearly everything involving his identity is a plot twist. He's the twin brother of Yoriichi Tsugikuni, the direct ancestor of Muichiro Tokito, the demon responsible for turning Zenitsu's senior Kaigaku into demon himself, and in his first and only battle, he slays Muichiro and Genya Shinezugawa.
  • Perhaps the biggest example is Demon Tanjiro. After Muzan is defeated, he manages to turn The Hero into a demon, resulting in him being the Post-Final Boss of the series.
• DNA²:
  • Mori gets mentioned by name a few times, but nothing beyond that can be listed without revealing that he's The Chessmaster to have orchestrated majority of the plot. And that he plans to use mind-controlled PSI Soldiers to stage a world war to fix the future's overpopulation problem by eradicating those that he deems worthless.
  • Jun Momonari has a much smaller role and doesn't even get a full facial reveal, but just his name is already an indicator that he is related to the protagonist Junta.
• Dragon Ball:
  • Dragon Ball Z had Raditz, being Goku's brother who reveals that they're both from a race of alien conquerors.
  • Dragon Ball Super has an odd case: Jaco is a relatively minor character in the show proper. but the fact that he's in the Dragon Ball universe at all spoils that his own manga is a Stealth Prequel.
• Elfen Lied: Tomoo, the Enfant Terrible and sociopathic bully from Kaede's orphanage, will forever be entirely associated with how Kaede began her Start of Darkness and became Lucy via his horrific treatment of her, most infamously his murdering a puppy she was caring for just so he could get any kind of reaction out of her.
• Evillious Chronicles:
  • Ney Futipe, a seemingly minor character in Cloture of Yellow until she's revealed at the end to be The Mole. Then comes the later revelations that she's the illegitimate child of Prim and Arth, as well as one of the incarnations of Gretel.
  • Just stating the name Cherubim Venomania gives away The Reveal in The Lunacy Of Duke Venomania pertaining to Steriasis's true identity.
  • The Demon of Gluttony, mostly thanks to him being killed, absorbed, and replaced by Banica Conchita at the end of Evil Food Eater Conchita, who goes on to become Master Of The Graveyard and one of the franchises main villains.
  • Sickle, who is the Top God and Big Good. Knowing this radically rewrites what one knows about the origins of the series world, religion and Levia-Behemo.
  • Eve Moonlit, the Original Sinner, who is revealed at the end of Gift From the Princess Who Brought Sleep to be the true identity of the Demon of Sloth, as well as Mikulia Calaground, Platonic and Margarita Blankenheim.
  • From the same novel there's also Mayrana Blossom, whose existence as Julia's body double isn't given until The Reveal.
  • Irregular, who is revealed in Seven Crimes And Punishments to, against all implication, not be the same individual as Allen. The same book also has Punishment, whose very existence isn't even hinted at until his brief appearance at the end.
  • Seth Twiright, the researcher referenced multiple times in Original Sin Story, until there comes the big bombshell late into Fifth Pierrot that he's the Demon of Wrath.
• Fairy Tail:
  • Zero is the Greater-Scope Villain of the Nirvana arc and the Superpowered Evil Side of Brain, the Big Bad of the arc. Zero doesn't appear until all of the other members of the Oración Seis are defeated, and his existence has little Foreshadowing.
  • Queen Chagot at first seems to be The Man Behind the Man to King Faust, and is even regarded as a deity. But it turns out that Faust is acting on his own terms, and that Chagot is hardly a deity. She ultimately isn't as evil as initially assumed.
  • Zeref. Even the fact that he's alive at all is a spoiler; this combined with him being quite different then how he had been originally described makes it essentially impossible to mention him to someone who hasn't read up to the point where he appears without spoiling something. Even his last name spoils a major element in the series.
  • Acnologia first appears out of nowhere at the end of the Sirius Island arc (same arc in which Zeref is revealed) to nuke the entire island, leading to the members of Fairy Tail frozen in time for seven years. He then is revealed to be a dragonslayer turned Dragon and is the main reason they're not around anymore.
  • Future Lucy and Future Rogue for mainly being from the Bad Future, and are not revealed until the end of the Grand Magic Games arc. Same thing with the seven dragons from the future that come back to present day.
  • Silver from the Tartaros dark guild is revealed to be Gray's father and possessed by the demon Deliora. Except the second reveal isn't true, and he just wants Gray to kill him.
  • The reason that E.N.D., the guildmaster of Tartaros, is only referred to by an acronym is because his full name is Etherious Natsu Dragneel.
  • Showing a single image of Gray after the second Time Skip is almost certain to be a giveaway of his (faked) Face–Heel Turn.
  • Anna Heartfilia is difficult to talk about without revealing her role in Zeref's ultimate plan or that she traveled from 400 years in the past to the present, and plays a role in the Final Battle.
• Fly Me to the Moon has Iwakasa, the subordinate of the emperor in The Tale of the Bamboo Cutter and Tsukasa's father. Instead of burning the Hourai elixir, he gave it to his daughter, making her immortal and making the entre plot of the series possible.
• Fruits Basket: Akito Sohma - specifically, her gender. Many of her entries either blank out her name or blank out her pronouns, although it's also acceptable to simply call Akito a "he", considering that everyone in-story (including Akito herself) refers to her as such until the tail end.
• Fullmetal Alchemist:
  • King Bradley is difficult to mention without revealing that he's secretly the Homunculus Wrath (Pride in Fullmetal Alchemist (2003)).
  • His "son", Selim Bradley/Pride even more-so. It's nicely handled on the character page by listing them as separate characters on separate pages, though Pride is pretty much an all-white entry as a result.
  • The shapeshifting Homunculus Envy is difficult to discuss without mentioning their two major contributions to the plot — murdering Maes Hughes and morphing their body into an Amestrian soldier to cause the Ishvalan Civil War by shooting an Ishvalan child.
  • Shou Tucker will forever be entirely associated with his horrific acts of turning first his own wife, then his own five-year-old daughter and her dog into broken chimeras out of desperation to acquire and keep his high-paying job, earning him the distinction of being the only character in the entire series to go to Hell in author Hiromu Arakawa's "In Memoriam" omakes in the manga, which is quite an accomplishment in a series with plenty of other dastardly villains (that get much more screen-time).
    • By extension, his daughter Nina is a Walking Spoiler, too. Her fate has a big impact on Ed and Al's Character Development and how they view and use alchemy. Ed even mentions her near the end of the series, just before giving up his ability to use alchemy in exchange for taking his brother's body back from the Gate of Truth.
  • Ling Yao and the second incarnation of the homunculus Greed are very difficult to discuss without revealing that they are (more-or-less) one and the same, due to the latter possessing the former's body.
  • Everything about Father is a spoiler, including his appearance — which is identical to Hohenheim and thus reveals an important connection between them.
  • Fullmetal Alchemist (2003):
    • The Big Bad Dante is initially introduced as a friendly old alchemist, but has ties to Hohenheim's backstory, like Father from the manga. Even showing a picture of her later on will spoil that she possesses Lyra.
    • Lyra as well. She appeared early on and is a minor antagonist but appears again later on... Sort of.
• GaoGaiGar: Pizza of the Four Machine Kings a.k.a. Soldato J-002, pilot of the Giant Mechanoid King J-Der.
• Gintama: The only thing you can mention about Yoshida Shouyou without spoiling anything important is that he was Gintoki, Katsura and Takasugi's childhood teacher (and that alone is already a bit spoiler-y). Anything else consists of his death being Takasugi's Start of Darkness, that it was Gintoki who killed him and that he's -gasp- Not Quite Dead, among other even more spoileriffic things.
  • Utsuro for that matter. His voice actor alone should somewhat tip off who he really is.
• Girls' Last Tour:
  • The Grandfather, whose existence is simply minor at best and a Posthumous Character at worst, is spoilered out, as he's very connected to Chito and Yuuri in many ways where everything is a massive spoiler that it's impossible to talk about him, starting from 1) He's their caretaker since their birth since their parents were absent, 2) He's largely responsible for teaching Chito how to read books and drive the Kettenkrad that have become essential for their journey, 3) Speaking of their journey, he's the man behind the duo's journey to the entire megacity and subsequently the highest layer after a massive Civil War broke down within their town, meaning he's responsible for kickstarting the main plot of the manga after his death.
  • Yet another minor but significant example comes from Kanazawa's unnamed companion. While she is merely appearing only in pictures during the reveal in Chapter 12, talking about her is difficult without revealing some spoilers as it is a clue why Kanazawa is all by himself when he firstly meets Chito and Yuuri. It is not even accounting how Chito lampshades this very fact about it, which in itself is a spoiler.
• Girls und Panzer:
  • The Maus, technically treated as a character like some of the other tanks, is a surprise Black Forest unleashes on Oarai, to devastating effect; it only appears at the end of the penultimate episode of the first series.
  • Maho Nishizumi has a large number of tropes spoilered out, especially concerning that 1)she is defeated in the finals, 2)In Little Army, she won by firing on an enemy flag tank that went to rescue one from her team, and 3)Contrary to her initial first impression as an Aloof Big Sister, she actually loves Miho dearly, and chooses to be Nishizumi heiress so that Miho will not have to.
  • Koume Akeboshi, the girl Miho saved from drowning in the last tournament, and resulted in Black Forest's defeat. Her only scene involves her talking about that plot point and thanking Miho for saving her. Her name is essentially the only thing you can mention without spoiling it, albeit in large part because it's found in supplemental materials.
• Gundam:
  • Mobile Fighter G Gundam: The character page spoilers out every last entry (and the name) for Major Ulube Ishikawa, due to him being revealed as the Big Bad about, oh, four episodes from the end. Specially since until then, he was seen as the Reasonable Authority Figure of the series.
  • Mobile Suit Gundam SEED: Rau Le Creuset, whose status as Big Bad, Omnicidal Maniac, and clone of Al La Flaga are revealed in the last five episodes of the show.
  • Mobile Suit Gundam ZZ: Glemmy Toto, who is both The Starscream and a clone of Gihren Zabi, facts that aren't outed until the end.
  • Mobile Suit Gundam 00: Ribbons Almark, the real Big Bad of the first season and of the entire series.
  • Gundam Build Fighters Try: A mysterious girl sets off the events of the Island Wars OVA. Discussing anything more about her risks spoiling the fact that her parents are none other than Reiji and Aila Jyrkiäinen.
• Idolmaster: Xenoglossia: Yukiho Hagiwara, who initially appears as a shy girl with a tendency to fall asleep at various moments, but in the Christmas Episode is revealed to be Chihaya Kisaragi's friend and a spy for Turiavita, trying to help Chihaya get Imber back from Haruka, and goes as far as to snatch Imber's key from Haruka in the next episode after revealing her true motives and take Chihaya's (who gets Imber) place as Nubilum's pilot.
• Jewelpet Twinkle☆: Alma, the main antagonist, is full of twists - even her gender is one, but the biggest is that she's the heroine's crush's long lost twin sister.
• JoJo's Bizarre Adventure:
  • Mark, a minor character from Battle Tendency is this, as his only role in the story is being killed by the now awakened Pillar Men.
  • The fact that Dio is in Stardust Crusaders is a major spoiler, as he was believed to have died at the end of Phantom Blood. The same applies to Joseph Joestar (though his Disney Death in Battle Tendency only lasted a single chapter and was largely Played for Laughs).
  • Diamond Is Unbreakable:
    • Jotaro's presence gives away the fact that he survives Stardust Crusaders.
    • Shigechi is this, given that his one major contribution to the story is getting killed by Kira, provoking the heroes into beginning the hunt for him.
    • Hayato Kawajiri is only introduced into the story after Kira kills his father and steals his identity, so he naturally can't be talked about without mentioning that.
  • Golden Wind:
    • While their roles are minor, the presence of Koichi and Jotaro spoil the fact that both survive Diamond is Unbreakable. The former's usage of Echoes Act 3 throughout the beginning also spoils the evolutionary nature of his Stand (let alone the fact that it evolves twice).
    • The boss of Passione is a man who goes to great lengths to hide his identity, so obviously he's a Walking Spoiler. His name (Diavolo) and face are unknown until near the end of the Part. Another twist is that he has a Split Personality in Doppio, his Cloudcuckoolander right-hand-man.
    • Jean-Pierre Polnareff isn't a Walking Spoiler in Stardust Crusaders, as he is introduced early on and becomes an important ally. But he DOES become one in Golden Wind, where his appearance at the story's climax as the third-party who helps the heroes figure out the boss's identity as well as the key to defeating him is presented as a huge twist.
    • Scolippi is introduced near the very end of the Part, and can't be talked about without revealing which members of Team Bucciarati end up dead by the end.
  • Stone Ocean:
    • As before, Jotaro's presence spoils his survival of Diamond is Unbreakable.
    • While the existence of Weather Report is not a spoiler in of itself, the fact that he's an amnesiac Stand User is just about the only thing that can be talked about him, as anything else would spoil major plot points for the climax of the Part.
    • In the final chapter of the Part, we are introduced to two characters, Irene and Anakiss. Who are they? Why, none other than Jolyne and Anasui's replacements after Pucci succeeds in killing them and almost all of the heroes and resetting the whole universe. Good luck saying anything about them without spoiling the part's ending.
  • The final opponent of Steel Ball Run is not president Funny Valentine, the Big Bad of the story, but rather a copy of Diego Brando the president had summoned from another world. One who can use The World as its Stand. Seeing Dio Brando's iconic Stand ability make a return in the hands of a new character is a truly shocking surprise.
  • JoJolion:
    • Josefumi Kujo is impossible to talk about without spoiling one of the key mysteries about Josuke's Mysterious Past: Josuke is the result of a Fusion Dance between Josefumi and Yoshikage Kira.
    • Just about the only thing anyone can discuss about Toru without spoilers is that he's Yasuho's ex-boyfriend. Anything else about him would spoil the reveal that he's actually Wonder of U's User and the true mastermind behind the Rock Humans.
  • Certain Stands are also inherently spoilers:
    • In Stardust Crusaders, The World, DIO's Stand, is treated as a big mystery. The truth of its ability (it can freeze time) is only revealed after DIO uses it to kill one of the main characters during the final battle, making it practically impossible to discuss without spoiling the ending of Part 3.
    • Koichi's use of Echoes Act 3 in Golden Wind not only spoils his Stand's evolving in Diamond is Unbreakable, but also the fact that it does so twice.
    • The reveal of King Crimson is directly intertwined with the reveal that Passione's boss was Evil All Along.
    • The very concept of Requiem Stands is only introduced during the final battle of Golden Wind. Of particular note is Chariot Requiem, who simultaneously spoils not only the existence of Requiem Stands, but also Polnareff's aforementioned involvement in Part 5.
    • During the final chapters of Stone Ocean, Pucci's Stand, Whitesnake, evolves into C-Moon, and then into Made in Heaven. The very fact that his Stand evolves is a spoiler, but Made in Heaven is an especially huge one as it has the power to accelerate time until the universe collapses onto itself and is remade. Which Pucci then proceeds to do.
• K: Adolf K. Weismann seems at first to be a huge pileup of villain tropes, down to the Evil Laugh and Sephiroth hair. Then it turns out he's actually The Hero, memory-wiped and body-swapped. ...To be fair, he was possessed by the bad guy when he did the Evil Laugh, though.
• Kagerou Project: There are plenty examples to be found, but probably the biggest is Kano, who's background and true motives are huge twists for later in the series.
• Kill la Kill:
  • It gets hard to talk about the Life Fibers in the later half of the series without spoiling the fact that they're sentient aliens that had their hands in humanity's accelerated evolution. Consequently, any character that is related to them or has a hand in Ragyo's Evil Plan to bring the Life Fibers back to power is also spoilerific.
  • Ragyo herself qualifies, as she only makes sporadic appearances in the first half and her motives and character aren't established until later on.
  • Nui is easily the big one however, since she appears close to halfway in to deliver an absolutely game changing revelation. This is without giving away the fact that she's an Artificial Human.
• Loveless: Seimei Aoyagi has over half the tropes on his entry on the character paged blacked out after The Reveal that he's alive after having been assumed dead since the start of the story. The revelation that he's alive also completely turns his prior characterization as a loving older brother on its head.
• Lyrical Nanoha:
  • Alicia only gets mentioned with spoiler warnings since any discussion about her, from her role in the story, to her relationship with the characters, to her appearance, to her family name will reveal that Precia had another daughter before Fate... and that Fate was a failed attempt to revive her.
  • Rein a.k.a Reinforce Zwei. You know something must've happened to the first Reinforce when a character with the same name has the German word for two on her name.
• Magic Knight Rayearth: Princess Emeraude is revealed to be the Big Bad, not the Big Good.
• Mazinger:
  • Most of spoilers in Mazinger Z and Great Mazinger revolve around Kenzo Kabuto and Archduke Gorgon. The former one was thought being dead for a long while, but at the end of the series it was revealed he was alive. Oh, and he is The Hero's father. He also is a major character of the sequel, where he gets Killed Off for Real, so it is pretty much impossible talking about him with spoiling key plot points of both series. Gorgon's first appearance revealed the supposedly extinct Mykene civilization still existed. At the beggining he seemed another Obviously Evil Hell's ally, but in reality he was a Dragon with an Agenda was working for a Greater-Scope Villain as he plotted destroying both Dr. Hell and Mazinger-Z. He was successful on all accounts, so describe him means spoiling the end of the series.
  • Maria Grace Fleed from UFO Robo Grendizer is one of the cases where her mere name is already a spoiler. She is The Hero's sister. However, Duke was supposed to be the only Fleedian survivor and have no family left. Maria is one of the main characters, and you can not describe her without spoiling both facts. Geez, stating her last name is a complete giveaway. And then you have Rubina. Who is she? Big Bad King Vega's daughter and Duke Fleed's fiancée.
• Musuko ga Kawaikute Shikataganai Mazoku no Hahaoya: Zeke is a demon who works for a human-led organization called C.A.T.T. that polices demons in human society and monitors demons outside human society. He's portrayed as serious and stoic, has a particular interest in main character Lorem, and even agrees to bodyguard her infant son Gospel and human friend Chiharu. Anything beyond that becomes a spoiler as he's connected to both the Myth Arc and the main characters. For the Myth Arc, his poison powers are the source from which the Anti-Demonification weapon humanity used to turn the tide in their war with demons was built from. As for his connection to the main cast, Lorem reveals to Chiharu that Zeke is baby Gospel's father, and he's staying with C.A.T.T. to keep his wife and son off their radar as much as possible, not just because Lorem is infamous as one of the most powerful demons in the setting, and Gospel is potentially just as powerful, but as Zeke's child Gospel may be resistant, or even immune, to the A.D. weapons derived from Zeke's poison.
• My Hero Academia:
  • The Paranormal Liberation Front. At the end of the Meta Liberation Army Arc, the eponymous organization merges with the League of Villains, thereby creating the Paranormal Liberation Front, an unprecedentedly dangerous villain alliance.
  • Dabi's true name is Toya Todoroki, the supposedly dead eldest son of Endeavor and oldest brother of Shoto Todoroki. The Reveal of his true identity leads to a rather significant Wham Episode, but it's difficult to talk about him without spoiling this.
  • Yuga Aoyama is a secondary character for much of the series, but near the end, it is revealed that he is the traitor inside U.A. who leaked the location of the training camp, among other things, to All For One, and that he's actually Quirkless and got his Navel Laser Quirk from All For One. These aspects of his character are not only the biggest surprises, but they're also the most talked about.
• My-HiME: Shizuru initially seems like nothing more than the Student Council President and a friend of Natsuki's who occasionally helps her out. Then, in the last few episodes, she's revealed as a Hime and kills quite a few people for Natsuki's sake, while revealing that she is in love with Natsuki. Most discussion of her character tends to focus on her actions toward the end.
• My-Otome:
  • From the manga, there's Sergay Auguste Taiki, who, unlike his Punch-Clock Villain counterpart from the anime, has no redeeming qualities and turns out to be the Big Bad.
  • From anime and manga series, Lena Sayers. The spoiled twists are different for each adaptation, but one thing both versions of her have in common is that she's Arika's mother.
• My Little Goat has Natsuki's father, who is impossible to talk about without revealing that there is a very good reason why he's better off in Mother Goat's care.
• Naruto:
  • Danzo, due to his involvement in the Uchiha Massacre, as well as several other characters' backstories.
  • Madara Uchiha was this initially, since he was thought to be dead for a long time. Then it turns out that he was dead, and the guy who's been pretending to be him all this time is Obito Uchiha (who was not only thought to be dead, but was also formerly Kakashi's teammate). And now, Madara's other partner (Black) Zetsu forced the weakened Obito to revive him completely.
  • Itachi - who was Good All Along and whose death reveals many subsequent twists as a result. His brother Sasuke would've been one too, before his Face–Heel Turn became It Was His Sled (hard to hide considering it drives the plot of Shippuden and Part II in the manga), plus Sasuke is pretty much the Deuteragonist of the story.
  • Hashirama and Tobirama, the First and Second Hokages, after the revelation of their backstory, which basically put into motion a chain of events leading to the current timeline's ordeals.
  • Kaguya Ōtsutsuki, being the very first Chakra user and the mother of the Sage of Six Paths, dwarves every single other Walking Spoiler before her. This gets even worse once it is revealed that she is not a Posthumous Character and promptly proceeds to usurp Madara's position as the Big Bad.
  • And for the shippers, Himawari, whose mere existence makes her surname a spoiler. Her appearance alone^note She has Naruto's blue eyes and his' "whisker" marks on her face, and her hair is the same color and style as Hinata's pre-timeskip hair should tell you who her parents are.
• Neon Genesis Evangelion:
  • Though it's entered It Was His Sled territory now, most tropes about Yui Ikari and Unit 01, since the two are in fact one and the same, with Unit 01 containing Yui's soul. Yui's face is also considered a spoiler and is not revealed until late in the series because of her very close resemblance to Rei Ayanami, who is in fact a clone of Yui and a Replacement Goldfish for her husband Gendo.
  • Kaworu, not only for being the 17th Angel, but also because he doesn't appear until everything has already gone to hell.
  • In the third film of the remake Rebuild of Evangelion, it's impossible to talk about Sakura Suzuhara, Toji's little sister, appearance or role as a medical officer without spoiling the 14 years time skip.
• No Matter How I Look at It, It's You Guys' Fault I'm Not Popular!:
  • Given the Series Goal at beginning of the series was Tomoko's becoming social and popular. It's impossible to talk about Nemoto, Yuri, Yoshida, Ucchi, Mako, Asuka and most of the characters introduced post-Kyoto arc without mentioning that Tomoko manages to gain friends later on the manga.
  • Sachi intentionally separating hers and Minami's friend group and Minami's subsequent Took a Level in Kindness are the first things you are gonna hear if you start discussing Sachi.
• From Odd Taxi, there's Yuki Mitsuya... as in, both of them. The fake Yuki can't be talked about without revealing that she's actually Sakura Wadagaki, who killed the real Yuki to take her place as a member of Mystery Kiss, while the real Yuki can't be talked about without revealing she's the missing girl whose whereabouts is the mystery that kickstarts the plot, the fact that she's been Dead All Along, and the previously mentioned fact that the Yuki the audience knows about isn't the real Yuki.
• One Piece:
  • Just listing the main characters is a spoiler, as the series plays Five-Man Band straight, deconstructs and slowly averts it. A special mention goes to two antagonists who make Heel–Face Turn and join Luffy's crew.
    • Not only was Nico Robin second-in-command of Baroque Works, but she was completely unlike the other Straw Hats who'd joined thus far. Unlike other Straw Hats, she didn't have a flashback showing her past before she joined, a dream that she wanted to fulfill with the Straw Hats (her goal was mentioned after she asked to join), or a need she could fulfill for the crew.
    • Franky is somewhat more traditional, since the Straw Hats need a shipwright, but few would have suspected that they'd turn to the guy whose Family beat up Usopp twice and stole 200 million Belli from the crew.
    • And even among the crew who wasn't a villain to start off with Sanji became this because of his actual family. Good luck talking about him without mentioning his surname Vinsmoke after the Whole Cake Island Arc since his updated bounty includes it.
    • And then there's the main protagonist Monkey D. Luffy, while his personality isn't this his True Devil Fruit power that is discovered late in the Wano Country Arc is this with his updated bounty picture includes it.
  • Discussing Vivi typically reveals that she's undercover in Baroque Works as Ms. Wednesday, and with later developments that her family is the only one among the World Government that didn't become World Nobles. Oh, and her full name is Nefertari D. Vivi
  • It's difficult to talk about the four Cipher Pol agents undercover in Water 7, especially not Kaku and Lucci, without revealing their being The Mole.
  • Rouge — knowing anything about her (especially her full name) reveals that Luffy and Ace aren't even related.
  • It's impossible not to mention Sabo, who is revealed to be their other "brother". Even if you don't mind that particular revelation, there's the teeny problem about him being alive in a certain Wham Episode.
  • Blackbeard shows up as a minor character, albeit one who shares an awful lot in common with Luffy and briefly shares the spotlight with him. While he does become important later on, this jolly man turns out to be Luffy's Evil Counterpart and a true Chessmaster, matching Luffy's crewmates one for one with darker counterparts and manipulating everyone around him, including many other important characters we saw before, in his attempt to gain power and find the One Piece.
  • Poseidon: even being on a character page reveals that a Weapon of Mass Destruction is actually a Person of Mass Destruction.
  • Dragon the Revolutionary. His full name and status as Luffy's father is one of the most tightly held secrets within the series.
  • It's nigh impossible to talk about Imu without revealing that there is actually a higher power than the Five Elders, and that one of the the World Government's central tenets- that no one person can be allowed to rule the world- is actually a lie.
  • This is now the case with Kanjuro, the kabuki looking Samurai that is terrible at drawing. He was the traitor that sold out Zou and sold out Oden and his Samurai comrades. It's difficult to discuss his character while hiding that he's The Mole; there are separate entries for Kanjuro and Orochi's spy among the Red Scabbards on the Characters page.
  • Rocks D. Xebec is long since dead at the main point of the story, the thing is he was once the World's Strongest Man whose actions directly affected the Four Emperors, Garp, Gol D. Roger, and the World Government that continues to the present day via Blackbeard above.
• Ōoku: The Inner Chambers:
  • In a manga where the basic premise is 'what if shogunate Japan was a matriarchy?', it's hard to discuss Ienari's reign without revealing he's the first male shogun in generations.
  • It's also hard to discuss Iemochi, the last female shogun, and her relationship with Prince Kazu without revealing that Kazu is actually a Decomposite Character in this 'verse, the real Kazu ran away to a monastery, and the 'Kazu' that married Iemochi is actually his sister Chikako (which was the real life Kazu-no-miya's birth name).
• PandoraHearts: Jack Vessalius (who's basically a Walking Spoiler folded into two Walking Spoilers, since everything we thought we learned about him is essentially turned inside out in the series's biggest Wham Episode). There's also anything to do with Glen and his legacy, Lacie, and the majority of what actually happened one hundred years ago. And since nearly every character ends up with some significant tie to that incident, even and especially the protagonist himself, the series as a whole can be considered its own Walking Spoiler.
• Panty & Stocking with Garterbelt: Mayor Corset. His full name, description, and every trope pertaining to him are listed in the "Spoiler Characters" section for the show's character page.
• Penguindrum has a whole lot of twists and pieces to be put together, so naturally there are a lot of characters with heavily spoilered pages. Yet somehow, in amongst characters whose very identity is a spoiler, Kanba seems to have it worst, despite being one of the leads. This is because a lot of what he does even very early on in the anime (before the audience understands, of course) relates back to one really big spoiler, which also happens to represent one of the most complex and centralized parts of the plot. Not only that, his entire backstory is a spoiler as well.
• Perfect Blue has Rumi, Mima Kawagoe's manager and best friend. Other than that, her true role as the Big Bad of the film, the fact that she is impersonating Mima to please Me-Mania, and being a former pop idol singer like Mima are outright spoilers.
• Pretty Cure: Every Sixth Ranger is a Late-Arrival Spoiler. However, The Dragon Regina from Doki Doki! PreCure, started out as a villain, got quickly befriended by Mana, then Regina went nuts, then she became normal again and joined the Pretty Cure for about two episodes, and then she's brainwashed by her father. She's Put on a Bus for about 13 episodes, and when she's back, she gained the Miracle Dragon Glaive, one of the three legendary regalia. Regina is Mana's friend, but it's a spoiler that she's still a villain, while every Dark Magical Girl who wasn't an Evil Knockoff joined the Pretty Cures. And it's also a spoiler that she's not Cure Ace.
• The Promised Neverland: Peter Ratri. You can't really talk about him without mentioning that he's William Minerva's brother, that the Ratri family serves as ambassadors between the demon and human worlds, that he's got an experimental farm going with one of the main characters as a test subject...
• Puella Magi Madoka Magica is nearly half Wham Episodes, making it near impossible to talk about without revealing something, but some individuals are a cut above the rest.
  • Mami Tomoe's death is her most important "action", and talking about her or the story as a whole without pointing out that a main character is mercilessly killed three episodes in is rather difficult. Then Memetic Mutation turned her death into It Was His Sled.
  • Oktavia von Seckendorff, Sayaka's witch self, reveals that Magical Girls become witches as well as which character will be the first to do so on-screen.
  • Homura's identity, motivation, relationship with Madoka, and even her powers are all huge spoilers. Goes double for the pigtailed glasses-wearing version of Homura, who first appears when all this is revealed, and goes triple for her in Rebellion.
  • Madoka herself is not an example, but two of the forms she takes are: Kriemhild Gretchen, her witch form, and Ultimate Madoka, the Cosmic Entity she becomes in the final episode.
  • Kyouko only shows up after things go to hell, with everything about her character being related to the darker elements that were only hinted at prior, and all her major contributions are being involved in spoilerific events.
  • Kyubey is probably the biggest example aside from Homura. Although they appear to be a cute Mentor Mascot, they are a manipulative alien Hive Mind that serves as the true Big Bad. Everything about them, from their motives to their influence, is a twist. That being said, their true nature is likely the first thing you heard about them.
  • A bit of real life walking spoilers as well, the producers tried to keep the fact that Gen Urobuchi wrote the script a secret from viewers due to how he automatically ups the tragedy quotient of anything he's involved with. When his involvement was leaked he lied and said he wanted to write a heartwarming story for a change. When you consider how the story does end, it turns out the creators still got the last laugh overall.
• Record of Ragnarok:
  • The representatives of the tournament's sixth round are both this. Not only do their characters spoil some major reveals in the story, but their roles in the Ragnarok tournament completely change up how the tournament had played out until this point.
    • On the humans' side, there's Buddha. His introduction is already rather bad, with the reveal that he might be the creator of the Volund system, but the later reveal that he chooses to fight for humanity, rather than the gods as was planned, makes him an even bigger one.
    • On the gods' side, there's Zerofuku. His mere existence is a shock, having not existed in any mythology detailing the Seven Lucky Gods, so knowing about him not only spoils the reveal that the Seven Lucky Gods are actually one being, but also spoils that he will be fighting in Ragnarok, rather than Bishamonten liked planned. And if the existence of Zerofuku isn't a big enough spoiler, the existence of Hajun is, as just knowing he exists spoils the fact that Zerofuku is forcefully transformed into him, forcing Buddha to fight him too.
  • Hades is one of these, as while he's mentioned at previous points in the series, once he does finally appear during the sixth round, he can't be talked about without revealing some major spoilers, including the identity of the previously mentioned contestants of the round. It gets worse when, due to a hole in the gods' representatives after Buddha's defection, Hades announces that he will fight for the gods, despite not having been considered as a representative previously.
• Saki:
  • The eponymous main character's older sister, Teru. When she is first mentioned, it's implied that she and Saki are not on good terms at the moment, but Saki has fond memories of her. When she first appears in the present, she's become cold, detached, and refuses to acknowledge being related to Saki. That latter part is an unpleasant surprise to Saki, and is somewhat surprising considering what we had heard of Teru.
  • A so far unnamed girl is shaping up to be this, given her appearance in a series of flashbacks that implies that 1)she's somehow related to Saki and Teru, and 2)whatever happened to her is related to the Miyanaga family falling apart.
• Sakura Gari: Sakurako Saiki. While she appears relatively early in the story, her actual role in it as well as her twisted motivations aren't revealed until almost the end. Same goes to the fact that he is a boy named Youya.
• School-Live!:
  • It's hard to discuss the series, especially the manga as it is revealed under ten chapters in, without mentioning that Megu-nee is actually dead.
  • Ruu doesn't appear until after the girls leave the school. She's Rii's little sister who had never been referenced for. Even more of a spoiler is that Rii underwent a Sanity Slippage and Ruu is actually a teddy bear.
• Sunday Without God: Hampnie Hambart, who at first appears to be a main character but then dies in episode three. As with Mami Tomoe listed above, his death is his most important "action," so it can be difficult to summarize the series as Ai's journey without revealing that Hampnie isn't one of her traveling companions. The roles of Alice and Dee, who appear halfway through the anime, can also be difficult to summarize without spoiling that they're trapped in a "Groundhog Day" Loop and that one of them may actually be dead.
• Tegami Bachi: Letter Bee:
  • Talking about Gauche Suede at virtually any point after the first chapter is likely to involve spoilers; after delivering Lag to Cambel Litmus, he was promoted to the head office, then lost much of his heart, disappeared and ended up with Reverse. Much of the early story involves Lag finding out what happened to him.
  • "Roda", Noir's accomplice, who bears the name of Gauche's dingo. Discussing her inadvertently reveals Gauche's status as Noir.
  • Jick Barrol, given his status as a major antagonist complicit in the Amberground government's misdeeds, and Largo's father.
  • Spiritus, a Gaichuu that lives inside the artificial sun, is responsible for many disasters and tragedies, and is the Final Boss of the manga. Mentioning this character's existence spoils some of the main mysteries of the series.
• Tengen Toppa Gurren Lagann:
  • Nia's origin (the Spiral King's daughter) and raison d'être (she's the Anti-Spiral messenger) obviously cannot be revealed until the beginning of the end. Her entrance to the story is also partly this since she enters after a certain Wham Episode (Kamina's Death).
  • The Anti-Spirals. Discussing their existence spoils that there's a threat to humanity apart from the Beastmen, as well as how Lordgenome's tyranny was actually meant to protect the world from the Anti-Spirals returning to kill humanity.
• Tsubasa -RESERVoir CHRoNiCLE-: Any mention of the real Syaoran or real Sakura inherently spoils that the Syaoran and Sakura the series focuses on are clones.
• Any discussion of the old lady and the monkey researcher in Twilight Star Sui and Neri is next to impossible without mentioning that both are a mirage that Sui follows as they're Dead All Along. It's also impossible to talk about them without mentioning their involvement of the creation of Tetsunagi as a community, as well as their status as the island's Famous Ancestors who became a part of its creation.
• Zeno, the Yellow Dragon Warrior, in Yona of the Dawn. He is the last and most anticlimactic of the main characters to join the party, and is nearly impossible to (accurately) describe without getting into the fact that he’s a 2,000-plus year old immortal, unaging and unkillable, and is the original Yellow Dragon from the founding myth of Yona’s kingdom. There’s also his wife, Kaya: any discussion of her spoils that the apparently-teenage Zeno is more grown-up than he typically acts.
• Yu-Gi-Oh!:
  • Yu-Gi-Oh! Duel Monsters:
    • Marik's abusive father is difficult to talk about without mentioning how the pain he inflicted on his own son during the Tombkeeper's Initiation by carving hieroglyphs onto his back with a red-hot knife, was what created Dark Marik.
    • Priest Akhenaden (Aknadin) from the Memory World arc is eventually revealed to be the man who created the Millennium Items using a spellbook, making him single-handedly responsible for the entire story. He also initially appears to be a priest loyal to the Pharaoh, but is later revealed to secretly harbor jealously towards his deceased brother, believing his own son should be Pharaoh instead of his brother's. Thief King Bakura is able to bring this side of him out, leading to a Face–Heel Turn.
  • Yu-Gi-Oh! GX has a relatively minor character known as DD (The D)... who is responsible for murdering Aster (Edo) Phoenix's father. The impact is felt throughout the entire Society of Light arc, contributing much to Edo's personality and his search for the powerful Bloo-D card that will lead him to the culprit.
  • Yu-Gi-Oh! ARC-V has three characters, Leo Akaba, Zarc and Ray. Leo reveals the interdimensional war that takes center stage for the show and his backstory changes the context of the war as well as answers questions that have been around since the end of season 1. Zarc and Ray's very existence more or less spoil the entire Myth Arc of the show.
  • Yu-Gi-Oh! VRAINS:
    • Lightning is revealed to be the Big Bad of the entire series and the catalyst for nearly everything bad that happened during the entire series.
    • It's hard to talk about Ai during the final season without mentioning his Face–Heel Turn to become the Final Boss, in part to the pain he feels from losing all the other Ignis.
• Yuri is My Job!: Nene is a cook for the salon who's friends with Sumika. That's the most you can say about her without revealing that she's Nene Saionji, Sumika's former schwester, who dissolved her schwestership with Sumika to get together with Goeido, only for the latter to callously dump her.
• Raizen in YuYu Hakusho. Describing him in more than general terms reveals one of the biggest twists in the series, since he's Yusuke's demon ancestor.
