Spoiler Opening

Go To

"Oh no, we were only just too late, you’re lucky I wasn’t paying attention the 19 times the opening spoiled your death!"

The lush, detailed opening credits contain information about the cast or plot that nullifies surprises later in the series. Thus, it's pretty obvious that when someone apparently important shows up who isn't in the opening credits, they aren't going to be around for very long. Similarly, the series tries to pretend that someone isn't very important, but they're featured prominently in the credits.

Series that rely on Previously on… in order to keep viewers up to speed are especially prone to this. Because only the parts of the story arc relevant to the current episode get recapped, the viewer is tipped off that those parts of the story arc are about to show up.

This is also particularly common in adaptations, because the producers often assume that many viewers will already be familiar with at least the basic outline plot, because many viewers are only there because they want to see spoilery stuff from far ahead in the plot, and because adaptations of Long-Runners naturally have more they can spoil. In cases like those, it can also qualify as a Late-Arrival Spoiler.

A series can get around this by:

  • Bait-and-Switch Credits: having the opening have little to do with the actual plot.
  • Evolving Credits: updating the opening as events transpire in-series.
  • Shaping their opening credits to merely have depictions which foreshadow upcoming events.

A variation is where an unseen character or actor is kept hidden until the next installment, yet credited in the Closing Credits. Another variation is where vaguely famous names appear in the opening credits, so you can guess automatically that they're going to be fairly prominent in the episode before they even show up. In series with recurring characters that are not normally in the credits or a cameo from someone who left the show this can indicate their eventual presence in an episode ruining their unexpected entrance. These variants are often Enforced by the certain rules of Actor Unions,note  as noted by J. Michael Straczynski. Dead Star Walking can be either a straight-playing or an aversion of this subtrope, depending on how it's presented.

Overlaps with Foregone Conclusion. Compare Trailers Always Spoil. Contrast Not Named in Opening Credits, when the credits omit an actor's name and maintain the surprise. See also First-Episode Twist, which can often fall prey to this, though that can be averted with any of the above methods or just using a Title-Only Opening for that episode. If the opening does contain spoilers but it's impossible to know what it's spoiling without having already watched it, see Rewatch Bonus.

Since this is a spoiler trope, there will be unmarked spoilers below.


    open/close all folders 

    Asian Animation 
  • Inverted in Pleasant Goat and Big Big Wolf: Mighty Little Defenders. The credits feature artwork that summarizes the season's events, including the ending. This wouldn't be a problem, except these credits appear in every episode of that season, well before most of these plot points are even mentioned.


    Film — Animated 
  • Tangled: Flynn Rider announces he will die as the first line in the movie. He gets better.
  • Subverted in Rango. The owls say he'll die, implicitly at some point during the storyline. At the end, when it hasn't happened, one owl suggests he might die from a household accident. At some point after the timeframe of the movie.
  • Disney's Robin Hood (1973) did this by showing detached scenes from the movie's plot points in the opening credits. Every relevant character in the movie is shown with an animation of them solo from various important parts of the movie, and the animations for the rest of the credits is from the climax.

    Film — Live-Action 
  • The Ontological Mystery of Dark City is spoiled by the Opening Monologue, which is taken from a scene halfway through the movie. (Executive Meddling mandated the addition of the voiceover.) Future viewers: Do yourself a favour and watch the directors cut, which omits the monologue.
  • Subverted in Sleuth, which deliberately features an opening cast list which proves to be wildly inaccurate.
  • Saving Private Ryan's opening subverts the trope, with the prologue of the old man concluding with a graphic Match Cut to...John Miller. (The old man later turns out to actually be Ryan.) Played straight if you're a bit more knowledgable about the American Army: the old man is wearing a pin of the 101st Airborne (Screaming Eagles), and Ryan is the only principal character in the film in that division.
  • Averted in Se7en: the actor playing John Doe is missing from the opening credits instead receiving the first credit at the ending.
  • The Mockbuster Paranormal Entity takes this to extremes. Three minutes into the film, it is revealed that the protagonist's sister is dead, he went to jail for her murder, he hung himself, and then his mother (who got possessed) hung herself too. The remaining 87 minutes of the film are pointless.
  • The opening credits of GoldenEye make it fairly plain that we haven't seen the last of Sean Bean, despite his character being "killed" before the credits even rolled.
  • This is avoided in the opening of Star Trek III: The Search for Spock...but there is an extra long pause between William Shatner's credit and DeForest Kelley's, where Leonard Nimoy's name would usually appear. In fact, the screen goes white at the moment when his name would appear, so one could imagine Nimoy's name "appearing" in white-on-white.
  • Want to watch Bedknobs and Broomsticks and not know the ending? Stop watching the opening credits when Donald McKayle is credited for the choreography!
  • In the film adaptation of Eragon, along with being almost nothing like the book, the audience is informed of the fact that Arya is a princess during the opening narration and plot set up. A fact that readers didn't find out about until halfway through the second book.
  • In the film Horsemen (starring Dennis Quaid), Ziyi Zhang has second billing in the opening credits. Even if you didn't recognize the name, the fact that she's the only Asian actor in the movie gives away the fact that her character is more than she seems to be when she is first introduced.
  • The opening narration of Moulin Rouge! by Christian clearly states "the woman I loved is dead."
  • The opening narration of Hop spoils the fact that the main human character becomes the first human Easter Bunny. This concept isn't introduced until a little before the climax, after a movie of basically nothing happening.
  • The German version of The Who's Tommy has an opening narration that states "Tommy can not be dubbed!" in this exact words. The narrator then proceeds to give an overview of the film's plot which means he gives away every plot twist until the very last moment of the film as if he was reading the synopsis off of Wikipedia. The narration also plays over the first two minutes of the film where Tommy's parents meet until the start of the war and cancels out any music. Then the movie proceeds with subtitles, making the inclusion of the narrator completely pointless.
  • The opening several minutes of Melancholia play out the entire plot in a series of stylized images.
  • In the opening credits to George of the Jungle 2, the song gives away several plot points. The first movie's opening song cut off before it got to the extended cut's plot summary.
  • The credits to Kill Bill Volume 1 give away the fact that he is portrayed by David Carradine, despite the fact that his face is hidden until Volume 2. Although fans of Carradine's work would likely recognize his distinct voice anyway.
  • Fathom Events, a company that distributes special event filmsnote  to cinemas such as AMC, often likes to put in making of featurettes before the movie, which often contain clips or information that can blow certain plot details for people seeing the films for the first time. This video mentions the following three examples:
    • During the making of featurette for Death Note: The Last Name, key scenes from the film were shown and it was revealed that the film was a two-parter.
    • When Rambo IV was shown in 2008, Sylvester Stallone showed the alternate ending of the first movie where Rambo died during the making-of documentary. The Rambo sequels were also mentioned in the preshow.
    • The 2009 hi-definition event of The Wizard of Oz spoiled many of the scenes from the film during the documentary shown before it, including the ending.
    • An interview that played before the Insider Access to Inside Out event spoiled Bing Bong's death when talking about how his voice actor (Richard Kind) cried while recording the character's last words: "Take her to the moon for me...okay?". What's even worse is that the trailers for the event spoiled some parts of the movie's climax, including the scene where Joy runs through Imagination Land, the scene where Anger gives Riley the idea to run away and the scene where Joy and Sadness splat onto the window of Headquarters after Fear says "I wish Joy was here!"note 
    • The 2018 "Jim Henson Holiday Special" screening of Emmet Otter's Jug-Band Christmas and The Bells of Fraggle Rock has a 5-minute documentary hosted by Amy Poehler that has a few spoilers for the former special.
    • Thankfully, this has gotten less frequent, possibly due to the complaints they've received. Many events nowadays either put the bonus content after the movie (such as the Doctor Who 50th Anniversary special and The Iron Giant), use clips that don't spoil much of the movie (such as Team Hot Wheels: The Origin Of Awesome, which used clips from the first 20 minutes, which were already available for free on YouTube), use no clips at all (Some examples include the 2015 showings of The Wizard of Oz and Grease, or for that matter anything else screened under the "TCM Big Screen Classics" banner, which have introductions by Turner Classic Movies hosts that don't spoil anything, but instead reveal tidbits about the movie you are about to watch - such as how Oz was not very successful in its initial run, but was Vindicated by History many years later when it was first shown on TV) or interview the cast (such as One Direction: Where We Are and Dragon Ball Z: Resurrection 'F'note ).
  • Enforced with Zardoz. Arthur Frayn's Breaking the Fourth Wall opening monologue where he literally explains the plot of the movie was added by John Boorman after test audience found the movie incomprehensible.
  • The 1995 20th Anniversary Collector's Edition home video release of Jaws included a making-of retrospective.... which played before the main feature, revealing every single plot element including the ending.

  • If you're reading one of Edward Rutherford's multi-generation historical novels (Sarum, London, etc), don't even glance at the family tree at the front of the book until you've read the whole thing: it'll spoil who has kids with whom, etc.
  • Artemis Fowl: The first page of The Last Guardian says (at the bottom, in Gnommish): The Last Will and Testament of Artemis Fowl.
  • In an in-Verse example, the elaborate LARP Games of the Dream Park series are nearly always preceded by a formal recitation of the rules of play. One such rule commonly stipulates how many lost points a player can reclaim if, having been "killed out", they return "from the grave" as a zombie, tornrait, or other undead. Which, naturally, prematurely reveals that there are undead as part of the Game's internal mythos and plotline.
  • The cover of the third book of The Icewind Dale Trilogy shows the heroes fighting demons in Tartarus, which only happens at the very end of the book. Also, Bruenor is shown on the cover, who was thought dead in the previous book and makes a surprising return in this book.
  • The Nature of Predators: The "Memory Transcription Subject" line at the beginning of each chapter spoils that the character should wind up surviving long enough to have their memories transcribed after the events of the story. This is Subverted Trope in the case of UN secretary-general Elias Meier, whose death is revealed in chapter 68, along with the fact that a brain scan was conducted shortly after his death by a group of xenophobic Venlil in order to figure out what seperates the "good" humans from the "bad" humans.
  • From the introduction of Slaughterhouse-Five:
    I've finished my war book now... It begins like this:
    Billy Pilgrim has come unstuck in time.
    It ends like this:
  • Stephenie Meyer managed to spoil Twilight (2005)'s plot twist on the back of the book. Then again, Edward being a vampire is the entire premise, so it's not like anyone picked the book up without already knowing the twist.

    Puppet Shows 
  • The Noddy Shop's intro shows several characters who won't be introduced until the second episode, namely Warloworth Q. Weasel.

  • Many Shakespeare plays spoil the ending in the prologue, which was basically their point. The enjoyment of the story wasn't to be surprised by the outcome, but to see how it gets there. For example, Romeo and Juliet states that Romeo and Juliet die. In fact, many plays are referred to as tragedies right on the title pages of printed editions, so you know that things turn out poorly before you've read a word.
  • The 2005 stage musical Willy Wonka is a Charlie and the Chocolate Factory adaptation that's Truer to the Text than the 1971 film version but uses its songs. The opening scene takes place in the factory, with Willy Wonka the first character the audience meets, and he goes on to reveal that he's planning to retire, but not before he finds an heir. In the book and most adaptations, he does not appear until the other characters arrive at the factory for the Golden Ticket tour and The Reveal that he's been seeking an heir all along is the climax of the story (he does appear in a few flashbacks in the first half of the 2005 film in order to explain the backstory, but his face is usually obscured and by the time he appears in the second half, he's...changed a bit). While the story is well-known and parodied enough to qualify as It Was His Sled, and Mr. Wonka is the most memorable character in it, this opening not only spoils the whole show, but negates the attempts in subsequent scenes to build up any mystery surrounding Mr. Wonka.

    Visual Novels 
  • The first opening of Fate/stay night shows Rin and Sakura depressingly turning away from each other. At first, it seems that it's because they're both Shirou's love interest in their respective routes, but it hints at their true relationship.
  • Each time you start a new game in Little Busters!, you are shown a pretty cool opening video for the game displaying many beautiful CGs. The problem is that a lot of them are from late in the routes and so implicitly or explicitly spoilery.
  • In Danganronpa: Trigger Happy Havoc's opening movie, a few brief images of Leon's execution are visible, including an almost-clear shot of his face just before being executed. It also shows brief footage of Makoto's execution in Chapter Five. The Anime of the Game went out of its way to avert this by showing all 15 students in the courtroom and the elevator leading down to it, in order to avoid spoiling who dies first.
  • In Takeshi's perspective of Ever17, it's revealed near the end of each route that there is a secret facility deeper underwater, directly under LeMU. However, the observant will notice something very clearly visible under LeMU in the very first shot of the opening video. It's not clear what it is, but after reading the story for a while, one can guess it's pretty much unknown to the characters and will probably become important eventually.
  • The PC opening of Steins;Gate was not subtile about its images compared to the other versions (Mainly because they use Freeze-Frame Bonus or the scenes were used out of context); showcasing Moeka's death, Mayuri's first death by head shot, Mayuri's second death by car crash, Tennouji's suicide, Dr Nakabachi trying to kill Kurisu and the satellite who crashed into Radio-Kaikan being a time machine. All of them being major plot twists.
  • The Ace Attorney series likes to play around with this. Each episode begins with a sequence related to the case at hand. While each of these sequences does depict actual events which are revealed as the case progresses, they are often times misleading or only tangentially related to the murder. Only five times throughout the series is the real killer clearly shown in the act in the prologue scene.

  • Grim Trigger: Volume one's opening sequence spoils Tage and Hunter working together. The first two credits also spoil Lodin and Proxy joining them.
  • The third chapter intro for PepsiaPhobia spoils both Mania's introduction and the appearance of her human form.
  • The opening pages of Reversed Star show Icaruss and Evangeline fighting together in a war, which makes the fact that he will eventually reach her a Foregone Conclusion. Most of the dramatic tension instead comes from how he does it, and how he and Evangeline become the people that they are by that point.

    Web Original 
  • The fourth season of Flander's Company has Clara appearing in the credits along the other employees, completely spoiling both her return and her Heel–Face Turn.
  • Princess Natasha: Oleg doesn't appear until episode 3, but the intro reveals his role from the very start.
  • The first season of Red vs. Blue always had Tex in the opening, even if it takes ten episodes (released over two months) for the first appearance. At least it hid another more important thing.
  • RWBY:
    • The Volume 1 opening reveals which characters will be on the same team many episodes before it happens, and reveals a character that has a cameo in the pilot episode is going to be a major villain; without the opening credits, this villain only returns in The Stinger at the end of the volume to reveal she's Roman's boss rather than a lackey.
    • The Volume 4 opening shows Blake aboard a ship with companions. When Episode 3 introduces her being followed around the ship by a hooded figure, it's easy to guess the stalker's identity before the in-episode reveal occurs.
    • The Volume 7 opening includes such a big spoiler that the writers asked the fandom to watch the first episode before watching the opening credits. This isn't a problem for most people as first episodes are always a cold opening with the opening credits occurring at the end of the episode and then opening all subsequent episodes in the volume. However, opening credits are also often released online as a teaser before the pilot episode. Fans who are used to checking out the opening credits before the first episode drops were asked not to do so this time. The opening credits reveal that Penny, who was destroyed in Volume 3, has been rebuilt and returns to the show.
  • Splinter Cell: Extinction: the shot with Julian Hunter reaching out to Corbin from the helicopter, spoiling the penultimate episode and finale.
  • Video Game High School: Inverted in Season 3. The closing credits don't change between episodes, so attentive viewers will notice that Nathan Kress plays "New Law" as early as Season 3 Episode 1.
  • The animated credits for Campaign 2 of Critical Role very prominently lack a certain purple tiefling, where the only reference to him is a shot of a snow covered grave marked by his trademark coat. His inclusion in the Dungeon Master's book as of 112 also spoils his mysterious return.

    Western Animation 
  • Adventure Time. Just pay attention to the first 5 seconds of the opening, and you will get spoiled with one of the biggest plot twists in the whole series: the fact that Ooo is actually the remains of Earth after a giant nuclear war.
  • Amphibia: The opening sequence for the third season spoils the ending of the previous season, wherein the show shifts locations from the titular Amphibia to Anne's hometown of Los Angeles back on Earth. The sequence also reveals that Marcy is still alive, which happens to be the only reason why the season two finale wasn't edited, as the creator agreed to have the new title sequence added as an after-credits scene to mitigate the tension of her apparent death instead. It also shows Andrias' robots flying through the skies of Earth, indicating that his invasion was going to get through.
  • The intro to Animaniacs features characters that are in skits that don't even premiere until a few episodes in, like Goodfeathers, Slappy Squirrel, Buttons and Mindy and Rita and Runt. As the show aired on Monday through Fridays during its run, these spoilers lasted for at least two weeks.
  • Avatar: The Last Airbender:
    • Episodes will often open with a recap of anything from an earlier episode that is related to the current one in any way. As such, if scenes from the episode "Jet" shows up in the recap, don't be surprised about the character Jet suddenly showing up. A bigger example is The Order of the White Lotus, whose importance to the plot was hinted at extremely early because of this.
    • The opening to the season 2 finale "Crossroads of Destiny" ends with a flashback to Roku ominously telling Aang "If you are killed in the Avatar State, the reincarnation cycle will be broken, and the Avatar will cease to exist." No points for guessing what very nearly happens at the climax of the episode.
    • An alternate opening narration for the first episode averts this trope, as Katara gives more information on the war and the Avatar but doesn't mention Aang because she hasn't met him yet.
  • The Avengers: Earth's Mightiest Heroes shows in its original intro that Captain America survived getting thrown into an icy sea, negating the attempts that Cap's debut episode made to make his fate seem ambiguous. It also shows Hank Pym becoming Giant-Man, an ability he doesn't demonstrate until his second appearance (chronologically speaking) Additionally, episodes set before the founding of the Avengers show eight members in the intro's Team Shot, revealing that Hawkeye won't remain an enemy of the heroes for long. The recaps attached to season two episodes also spoil the returns of certain antagonists by showing their previous appearances.
  • The opening of season 2 of Big Hero 6: The Series has a quick shot of Liv Amara with the other villains, who was only revealed to be villainous in the second episode of the season, though there were hints in the first season.
  • Averted with Blinky Bill; so as not to immediately spoil the story arc of season 3, the first two episodes of the season use an alternate intro, featuring clips from throughout the season note , and set to a modified version of season 2's theme song.
  • Elena of Avalor: The Season 3 intro removes Esteban from the "With her family by her side" scene and the group shot at the end, hinting that something happens that causes Esteban to be absent. This intro debuts the same episode where we learn why he's missing from the intro (he has been disowned and is now a wanted fugitive). A big glaringly, Isabel also has an updated animation model in this episode, but the scenes retained from the previous intros still feature her in her original animation model, so this new intro variant was clearly meant to foreshadow Esteban's fate.
  • Exo Squad: The opening narration talks about a war between the Neo-Sapiens and the Humans... a war which only STARTS in the sixth episode. This is made all the more confusing by the fact that that a Human/Neo-Sapien war took place in the show's backstory (but not the war the opening narration shows clips of).
  • The intro for Gargoyles is comprised of scenes from the show's Pilot Movie, which causes problems when you're watching it as a five-part episode.
  • In Gravity Falls, the intro features a few blink-and-you'll-miss-it spoilers, such as Li'l Gideon Gleeful and two separate appearances by Bill Cipher. One of the latter, at least, is a brief sketch of him on paper covered in cryptic gibberish that's easy to write off unless you know what's going on, but the second is a full-screen image that shows up in a momentary but jarring fashion just as the show's name is onscreen, making it fairly noticeable and creepy.
  • Hilda: Each season has a unique opening which features characters and settings that are explored in that season. This means that, for earlier episodes of a season, characters that have yet to be seen will be sighted in the intro first.
  • Jackie Chan Adventures:
    • The intro for season 2 showed that Valmont would be possessed by Shendu for season 2.
    • Even before Valmont and his three last Enforcers (Finn, Ratso and Chow) met Daolon Wong, the Season 3 intro revealed the Enforcers becoming Wong's Dark Chi Warriors and it did not feature Valmont, revealing the latter wouldn't appear as often as he did the previous story arcs.
    • Season 4's first episode started with a Previously on… showing scenes from when people other than Shendu controlled Shadowkhan and scenes from when Daolon Wong was depowered. Before the intro, Wong tried to regain control of Shadowkhan to make them break him out of prison but he instead awakens Tarakudo. Then the intro shows Tarakudo as that season's Big Bad, the Enforcers working for him and Wong not being featured.
    • Season 5's intro doesn't feature the Enforcers. Drago becoming the major antagonist was probably expected by the time the intro first started, but his featured henchmen wouldn't appear before his third episode.
  • The opening credits for Justice League, and later Justice League Unlimited, would show (sometimes spoileriffic) scenes from that particular episode.
  • The series pilot of Kaeloo, which gave away the entire episode plot.
  • Kim Possible:
    • Lord Monty a.k.a. Monkey Fist appears in the opening theme from the very first episode onwards, however his first appearance was not until episode 13, where it was written as if Monty turning out to be the bad guy was a big twist.
    • This happened again in the last season when the opening changed, spoiling Warmonga well before her episode appearance. Once again, her episode is written as if we're not supposed to have any idea who this other green-skinned lady who's helping Drakken who isn't Shego is.
  • The Legion of Super Heroes (2006) pilot "Man of Tomorrow" had spoilers in the opening credits, showing Timber Wolf, who wouldn't be making an appearance until the next episode.
  • * In Master Raindrop it happens with three of the five elements:
    • Jin Hou appears in the team in several scenes, so we know Raindrop would win the monks' competition for the right to keep him.
    • Its opening shows Niwa as the element Earth, but the main characters and antagonists thinking the Princess Jade was the element Earth was a plot pont.
    • It was worse with Shao Yen. She was treated as the token muggle with martial skills and it was an excuse for the big bad, General Bu, to leave her alone, or at least think at it. Just episodes later it was revealed she was the element Wood. Guess who the opening made a point of introducing as the element Wood since the first episode?
  • My Adventures with Superman: The opening sequence, first released on YouTube but first broadcast starting with the second episode (after the 2-part premiere), shows a bunch of villains before their proper introductions in the storyline, though only for a few seconds. Examples include Slade Wilson/Deathstroke (albeit he's not immediately recognisable in his Powered Armour), and Mr. Mxyzptlk with Glowing Eyes of Doom spoiling that his claims to Clark about being an inter-dimensional peacekeeper on introduction are complete bunk. An inversion occurs with Mist, who is absent despite the other members of Intergang being shown, helping to support his claims of evading Task Force X in "Zero Day, Part 1" before it's revealed that he's actually The Bait luring Superman into an ambush. Most importantly, Nemesis Omega, a being referred to throughout the series is shown prominently in the middle of the screen along with his spaceship, but far back enough to be out of focus despite his overarching influence on the plot. The framing also makes him look similarly-sized to Clark as well, highlighting their opposing roles.
  • My Little Pony: Friendship Is Magic has the Japanese dub opening sequences, the 3rd opening being the biggest example, as it spoils the ending for the season two finale A Canterlot Wedding.
  • Phineas and Ferb: The "Night of the Living Pharmacists" title sequence shows an animation of Perry's footprints being zapped by electricity and turning into Doofenshmirtz's footprints, spoiling the ending that includes Perry being transformed into a Doofenzombie.
  • In ReBoot, every four episodes of seasons 3 and 4 had an opening sequence using clips from those four episodes. Naturally plot developments like Enzo's Time Skip, the Saucy Mare's web armor, and Mainframe in ruins are spoiled. Averted with the Toonami broadcast, which replaced those openings with customized ones.
  • The opening credits for The Secret Saturdays feature the Saturdays being charged by a quartet of villains. While one of them, Piecemeal, shows up relatively early in episode 4, the others are Eterno, a one-shot villain who doesn't show up for several more episodes, Rani Naga, who also doesn't appear until almost the end of the season, and Shoji Fuzen, who appears in episode 3, but is wearing blue samurai armor he won't don until many episodes later.
  • Steven Universe:
    • The second intro shows Connie carrying Rose's sword, spoiling that she'd be trained as a swordfighter (which happens in the intro's debut episode) and that it would become her usual weapon (which happens ten episodes later).
    • Nine episodes into Steven Universe: Future, Steven is shocked to discover Sadie and Lars never got together and are moving on romantically. However, the opening already showed Sadie separate from Lars and hanging out with a new character (who turns out to be Sadie's new significant other).
    • The closing credits and Episode Title Cards have an emphasis on Steven driving his car which rather overtly hint at Steven moving out of Beach City at the end of the series. The show's creator has even stated that, while the title cards of the original series were set in the present, for Future they're always set after the end.
  • Teenage Mutant Ninja Turtles:
    • The opening of Teenage Mutant Ninja Turtles (2003) season 5: Fast Forward, spoils that Darius Dun, initially a minor supporting character, is the Big Bad (he is seen looming over all the other villains).
    • Despite being introduced as Shredder's lieutenants, Chris Bradford and Xever are strangely absent from the intro of Teenage Mutant Ninja Turtles (2012). Instead, Shredder is shown standing with the mutants Dogpound and Fishface. No prizes for guessing what's going to happen to Bradford and Xever.
  • Total Drama: The theme song of Action featured Courtney, who came back halfway through to the surprise of the castmates and (maybe) Chris. However, the flipbook itself had no intention of this ever being a spoiler.
  • Transformers:
    • The Japanese opening of Transformers: Animated spoils Longarm being a Decepticon, Blackarachnia commanding the Dinobots, Starscream's Allspark fragment and clones. However, there's also so much stuff that simply doesn't happen that it's hard for a new viewer to tell what's important and what isn't.
    • Megatron is presumed dead at the end of the five-episode opening arc for Transformers: Prime. While the odds of a Transformers outing killing off Megatron that early were already low, the opening credits then bump them down to nonexistent by prominently featuring Megatron.
    • The season 2 opening to Transformers: Cyberverse shows a cheetah-themed robot and prominently features Starscream donning yellow armour, so it's not much of a surprise when Starscream turns out to be Not Quite Dead and Cheetor joins the Autobots.
  • The opening of Trollhunters spoils the fact that Jim's love interest Claire is going to join the team while she spends the first half of the first season clueless about Jim and Toby's adventures.
  • The Episode Title Card for T.U.F.F. Puppy features pictures of major characters and objects in the featured episode; the last picture (with the "directed by" credit) will always be the featured villain. This could extend to someone turning evil (like Quacky the Duck), or someone revealed to be Evil All Along (like the Lunch Ladybug).
  • The first season of Wakfu has Yugo being Fastball Specialed into the Monster of the Week (or equivalent thereof) at the end of every opening. Even when the identity of said Monster of the Week was presented as a twist in the actual episode, such as the thief from ''Ruel's Bag''. Fortunately dropped by the second season.
  • The opening of X-Men: The Animated Series does not include Morph listed among the team's roster, making it fairly easy to guess that he won't be lasing all the way through the opening two-parter. Even after he comes back from the dead, he never rejoins the team full time.
  • The intro to X-Men: Evolution shows all of the X-Men gathered together and shows them off by name, despite the fact that half of them don't show up for several episodes. The most notable case is Rogue, who is introduced early on as a character, but keeps her allegiance uncertain until halfway through the season.
  • Young Justice:
    • One episode has the team helped out by an arrow fired from the shadows. When they confront Green Arrow and accuse him of babysitting them and he proves it wasn't his arrow, they assume his sidekick, Speedy, is ready to join the team after storming out in the pilot. Yeah ... or maybe it's the female archer who appears in the opening credits of the show as a team member despite having not appeared in the actual show yet at that point.
    • The team isn't completely assembled in story before episode 6, but the intro shows the whole team since episode 1.
    • Right before the show's logo is viewed, each Young Justice episode's opening contains a quick display of clips which previews events that occur later in whichever episode is airing at the moment which is at least less spoilery because of the rapid speed the images flash on the screen.
