Trailers Always Spoil / Western Animation

Go To

  • Pick a trailer, any trailer, for any episode of a 2010s Cartoon Network series. You've basically seen the entire episode in under 30 seconds.
    • For a particularly egregious one, the beginning of the trailer for Teen Titans Go!'s "Justice League's Next Top Talent Idol Star" (no, that's not a typo) Shows that Robin, Raven, and Cyborg were the final contestants.
    • And if the trailer for "Giant Woman" is any indication, Steven Universe might be starting to fall victim to this too.
      • A promo shown during StevenBomb 4 showed a clip from "Barn Mates" spoiling the return of Lapis Lazuli, which aired a full four months later.
    • Advertisement:
    • A less spoilery example, but one promo for the Regular Show episode "Go Viral" actually showed the ending of the episode (more specifically, the Farting Bear that was a Running Gag in it landing on Muscle Man).
      • Before the The Powerpuff Girls (2016) Episode Power-up Puff aired The Teaser shows Blossom finally getting her new powers.
      • The Russian version of Cartoon Network has proved to be extremely spoiler filled twice so far. First, it revealed Unikitty! before Cartoon Network announced the show, and then revealed what Bliss looked like prior to the Power of Four PPG 2016 special.

  • Played with in Archer. The first episode of season 5 ends with a Fantasy Sequence of Archer's that serves as a trailer for the rest of the season. It did include some genuine spoilers, but they were interlaced with things that never happened (like Cherlene getting kidnapped) and things that happened in completely different circumstances (like Lana going into labor).
  • Advertisement:
  • When Batman: The Animated Series originally aired on Fox, some of its promos could be pretty spoilerific, too. This one outright shows the cliffhanger ending of "Heart of Steel, Part 1" in it.
  • Promos for the first two Bionicle: The Journey to One episodes spoiled most of the ending by showing the sought-after Mask of Creation in the hands of the villains, from the very last scene. The only things not to get spoiled were Umarak kidnapping Ketar and mutating into a hulking beast upon putting on the mask, but these were already Spoiled by the Merchandise aynway.
  • One commercial for the series finale of Danny Phantom, "Phantom Planet", had the announcer outright state that Danny would loses his powers, get his powers back, have a Last Minute Hookup with Sam, and team up with every ghost in the series to stop the Disasteroid.
  • Advertisement:
  • The trailer for "Heather Report" in Dragons: Riders of Berk completely reveals that Heather is The Mole, working for Alvin.
  • During its original airing on The Disney Afternoon, the trailer for Part 1 of the DuckTales (1987) Grand Finale, "The Golden Goose", showed the cliffhanger ending of Huey, Dewey, and Louie getting turned into gold statues.
  • DuckTales (2017): A promo spoiled Magica De Spell's appearance.
  • In the Family Guy episode "The Splendid Source" (after Cleveland had left for The Cleveland Show): "Cleveland! Who would have thought we would run into you? Except everyone because Fox spoiled it in all the promos."
  • More Disney Channel screwing: In a Fish Hooks episode "Fail Fish", Milo has to pass a test in order to prevent himself from being held back a grade. This would have been taken as a surprise, if only they hadn't shown him holding the test in his hand while he shouts for joy, implying that he has passed it! You might not be able to catch it if you're not paying attention, but it's still there.
  • This print advertisement for The Flintstones special "Hollyrock-A-Bye-Baby" shows that Pebbles will have twins.
  • Black Phantom's defeat from the Hero Factory TV special was spoiled, shot for shot, on an on-line promo vid advertising the cartoon and characters (and their toys) on the LEGO website.
  • Nickelodeon showed various commercials of scenes leading up to the release of The Movie of Hey Arnold!. One of these completely spoiled that Helga finally confesses her love for Arnold. (They didn't show how he reacted to it, though.)
  • The ads for The Movie and Grand Finale of Kim Possible (before it was Uncanceled), So the Drama, show the High-School Dance moments leading up to the the final kiss between Kim and Ron, something shippers have been hoping for since Season 1. They didn't even attempt to Ship Tease the fans with the Romantic False Lead, Eric. Obviously they believed fans needed MORE incentive to watch the show.
    • As if that wasn't enough, one of said ads actually showed a clip of Kim being shocked by Eric while he had an evil look on his face, which would pretty much give away that he's really working for Drakken.
  • The trailer for the first season finale for The Legend of Korra was shown when there was still one episode to go before it, and spoiled that the Equalists will get control of the city and begin mass bending removal.
  • Some The Loud House promos can be spoilerific. This promo gave away the ending of "No Spoilers", and this promo gave away the climax AND the ending of "Snow Way Down", too.
    • The YESvember music video on Nickelodeon's YouTube channel includes a scene from the episode 11 Louds a Leapin', spoiling the reveal of Mr. and Mrs. Loud's faces. The video was eventually reposted with that particular clip replaced with a scene from The Thundermans episode "Winter Thunderland".
  • A promo for the Motorcity episode "Like Father, Like Daughter" spoiled the ending in which Julie agrees to take over KaneCo should something happen to her father.
  • The trailers for the My Little Pony: Friendship Is Magic episode "Magical Mystery Cure" included a clip of Fluttershy saying "You look just like a princess!", completely spoiling the game-changing twist (That everyone already knew about) that occurs the very end of the episode. And then, Hasbro proceeded to plaster this plot twist all over all over their commercials and toys. Additionally, a sign depicting Twilight Sparkle with wings was actually sighted months before the episode was even announced, but was dismissed by most as an error from the artists while creators of the show even tried to save the twist by outright lying about it.
    • To the great annoyance of viewers who had spent most of season 4 (if not longer) awaiting the frequently-referenced Equestria Games (and especially of Rainbow Dash fans), a promo for the final episodes of the season included a very brief clip of Spitfire crossing the relay finish line narrowly but noticeably ahead of Dash.
    • Also, a promo for the Season 4 finale "Twilight's Kingdom" shows that the Golden Oaks Library, where Twilight has stayed since moving to Ponyville is destroyed by the new villain.
    • In the Hub trailers for the finale as well, the Royal Sisters and Princess Cadence lose their Cutie Marks when they transfer their magic to Princess Twilight, leaving them helpless to being made hostages/prisoners of the new villain. [1][2][3][4] The trailer also shows Twilight taking off so fast, she leave a crater in the ground, against a blood red sky.
      • About the only thing the trailer for the finale didn't spoil was that said villain was a FIM version of classic villain Tirek.
    • In another instance of using The Reveal to sell more toys, Hasbro announced in 2013 a new set of "Rainbow Power" toys featuring the ponies covered in rainbows. Around the same time, the season 4 premiere introduced a mysterious locked chest whose contents were unknown. At the very end of the season 4 finale, the ponies finally manage to open the chest, and a magical rainbow comes out and makes them change into "Rainbow Power" versions of themselves as a Super Mode, allowing them to defeat the villain. Way to reveal your big end-of-season twist early in order to sell more toys, Hasbro.
    • In another minor example of the toys spoiling the theme: several months before the first advertisements for season 5 were out, a new set of toys were released, the theme this time being Cutie Mark Magic. Guess what the theme of season 5 is?
    • The Discovery Family promo for season 8 features a particularly bad example of this, spoiling lots of big surprises like Starlight and Sunburst getting called by the Cutie Map, the return of Queen Chrysalis, and Spike getting wings.
      • Meanwhile, the synopsis for the season finale indicates Cozy Glow intends to take over the School of Friendship. This is despite the fact said character wasn't even introduced yet, and when she was, she was a simple one-shot character about halfway through the season.
    • In My Little Pony: Equestria Girls – Magical Movie Night: Movie Magic, the plot involves figuring out who is sabotaging the production of a movie. The synopsis for Mirror Magic indicates that Juniper Montage seeks revenge. Do the math.
  • Phineas and Ferb:
    • There's the episode "Candace Gets Busted". In order: It starts off as an intimate get-together, she has no problem inviting a few more people, but then it becomes a party, Linda calls the house and says they're coming home. Then guess what happens? "Young lady, you are so busted!"
      • To be fair, if you couldn't guess that was going to happen based on the title, well...
      • The Latin America dub averts this, where the episode is renamed "Candace's Party".
    • Then there's "Minor Monogram", where the commercials literally only showed the ending where Vanessa falls for Monty.
    • The Grand Finale completely spoils the end finale number "Curtain Call (Time Spent Together).
  • Ready Jet Go!:
    • The commercial for the week of new episodes in August 2016 spoiled Face 9000's new look.
    • Sometimes, this is a case of Episode Descriptions Always Spoil. For example, the description for "Mindy's Meteorite Stand" spoils the fact that Mindy's meteorite really wasn't a meteorite, but the big rock she was sitting on is, "Sunday Drive"'s description spoils that the Propulsions weren't on Mars, but an Earth desert, and the description for "Mindy's Mystery" spoiled that the mystery smell came from moonflowers, and the bright light that was bothering Mitchell was from the moon itself.
    • Zigzagged for the images the wiki provided for Season Two. While some images are tied to the episode's theme, some are just random screenshots. A few ridiculous examples of the latter include: The image for "Zerk Visits Earth" doesn't feature Zerk, the image for "Sunspot's Sunspot" doesn't feature Sunspot, the image for "Sean Has a Cold" depicts Sean as completely healthy, and the image for "Mars Rock For Mom" is a frame from the the takeoff sequence.
  • The theatrical trailer for Rugrats in Paris had Don LaFontaine proudly introduce Kimi as "the newest Rugrat", therefore cluing the viewers in on how the movie ends (Chuckie's dad marries her mom) and her incorporation into the show.
  • Previews for the Rocko's Modern Life special Static Cling spoiled the reveal that the character formally known as Ralph transitioned into a woman named Rachel. Most of the LGBT Fanbase wasn't upset at the spoiler because the possibility of accurate representation in a kids' show just got them more excited.
  • A teaser for the second half of Scooby-Doo! Mystery Incorporated's second season clearly depicts Professor Pericles going One-Winged Angel after becoming the vessel for the Nibiru entity.
  • Parodied in The Simpsons with an old Radioactive Man film reel. A giant missile heads toward Earth, and cuts to a freeze frame while the announcer says, "Will Radioactive Man save the planet Earth? Find out next time!" The freeze frame shows Earth being split in half with a giant mushroom cloud.
    • That's more a parody of old adventure serials. They routinely ended with something terrible happening (e.g., the hero's car skids off a cliff) and an admonishment to see the next installment to find out how the hero would avoid his terrible fate. Invariably, the next installment would be a total cheat (e.g., the hero jumps out of the car before it reaches the edge - even though he was clearly in the driver's seat as the car went over in the previous installment).
    • The promos for the episode "How Munched is That Birdie in the Window" spoiled the whole plot of Bart adopting a wounded pigeon and Santa's Little Helper eating it.
    • The trailers for The Simpsons Movie show the exchange among Homer, Bart, and Russ Cargill near the end of the movie with the "treasure of I'm a weiner" joke. This spoiled the "To Be Continued... Right Now" joke as the latter takes place before the former in the movie, showing there is more.
    • The syndication promo for "When Flanders Failed" had Bart facing the bullies with his "karate skills". The announcer asked, "Will Bart get a black belt or a black eye?", followed by a cut to Bart hanging from a basketball hoop by his underwear.
  • Parodied in the South Park episode "Professor Chaos":
    Narrator: Will Professor Chaos succeed? Which boy will replace Kenny? Which adult cast member will die? These questions will be answered... right now. No, Tweek, and Ms. Choksondik.
    • Though that may have been intended as a parody for the (in)famous "Who is Eric Cartman's real father?" 2-parter, since a lot of fans were ticked off when they got the Terrance & Phillip special after waiting for a month, instead of the continuing story.
  • The episode "Squid Noir" From SpongeBob SquarePants was completely spoiled, when Nickelodeon launched a block called "You Bring The Color", and the website called to use the pictures from the end of this episode so kids can color the characters from the ending. No one even knew, until the altered ending got aired.
    • The made-for-TV movie Atlantis Squarepantis spoiled the climax where Plankton finds out he stole a tank that shoots ice cream. It wasn't like it was in a montage or anything either, they blatantly displayed it up front because they thought the punchline was funny enough to include. It got even worse when they put a Commercial Break Cliffhanger right before this moment.
  • From Disney XD's Star vs. the Forces of Evil, Promos from "The Battle of Mewni" spoiled most of the movie, including the teaser.
  • Star Wars: The Clone Wars restrained itself fairly well when it comes to foreshadowing Anakin's eventual transformation into Darth Vader, so naturally Cartoon Network was eager to promote an episode where Anakin has a vision of what he will become. Some pretty sweet clips were shown in the promos, but when the actual episode was aired, you realized they showed you the whole scene!
  • Star Wars Rebels:
    • The season 2 midseason trailer showed somewhat more of the finale than Dave Filoni would have liked, in particular the Sith holocron, the return of Darth Maul and Ahsoka and Vader's duel. However, it did not spoil some particularly major plot points, namely Ahsoka's Uncertain Doom and Kanan getting blinded.
    • It's not a surprise to anyone keeping up with the show, but the season 4 trailer has a shot of Kallus in a Rebel uniform, which to anyone only familiar with his character from the first two seasons would be unexpected to say the least.
  • Star Wars Resistance: The first season 2 trailer revealed that Kaz's father Senator Xiono, believed in the season 1 finale to have died in the destruction of Hosnian Prime, is alive.
  • Steven Universe tends to get hit very, very hard with this trope.
    • In the few days after Stevenbomb 4 alone, 2 clips were released on Cartoon Network's UK site as promos that revealed the return of Malachite and Lapis Lazuli, with said episode not airing until four months later.
    • It's arguably worse with the "Steven's Summer Adventures" event, during which the network aired the entire third season within a month and released significant portions of almost every episode early as "sneak peeks". In a particularly irritating move, they also uploaded clips and made news articles surrounding Bismuth being introduced, in which it is also shown that Amethyst has received another design change. It kind of makes you wonder whether any major development in the show will ever be allowed to go un-spoiled ever again.
    • Possibly the most notorious case thus far was in May 2018, due to it being an accident rather than an intentional marketing choice by the network. As part of a miniseries about animation production called "Drawn Podcast", Cartoon Network released an interview with Rebecca Sugar and Ian J.Q. In the video were short clips of unreleased episodes that were regarded as major spoilers for the remainder of the season, the most damning one being the final clip, which showed Steven peacefully interacting with Blue and Yellow Diamond before being set down next to the Crystal Gems, which includes a un-bubbled Bismuth: something that greatly changes the show's Status Quo. Even worse, this came after many members of the Crewniverse begged the fandom not to spoil upcoming episodes. Needless to say, fans were furious at the network and members of the Crewniverse were pretty distraughtnote . The video was quickly pulled by the network upon realization and reuploaded without the spoilery parts, but by then the damage was done. Most of the spoiled episodes would air two months later, with the episode featuring that final clip premiering online the following month.
  • Total Drama:
    • The original trailer for Total Drama World Tour (back when it was still being called Total Drama the Musical) spoiled Leshawna's elimination; also, if you look quick, it also spoils Ezekiel's elimination as well, as you can see he doesn't get a bag of airline peanuts after DJ.
    • A midseason trailer for Total Drama World Tour spoils when Lindsay's elimination happens.
    • Trailers for All Stars not only shows Alejandro out of the robot, but also Lindsay and Jo's elimination.
    • Another World Tour example would be where a promotional flier for the season used to have accidentally given away the final two of the last season. This was especially bad because, at the time, the flier came out when there were about six contestants remaining. It was changed before the season aired, but the information had long been out by then.
    • An Italian trailer for Pahkitew Island shows Beardo's elimination.
  • From an episode preview on The Transformers, "But is this really the end of Optimus Prime? Tune in for tomorrow's exciting episode: "The Return of Optimus Prime".
    • However, the first time that aired, it didn't have the narration. Thankfully, newer DVD releases go without it (though of course the DVD's episode list does let you know that an episode called "The Return of Optimus Prime" is coming up.)
    • Not to mention all the trailers for the movie showing clips of Optimus Prime getting blown to bits while the Narrator asks, "Does Prime die?!"
      • Then the very next question the Narrator asks is: "Then, who will lead the Autobots?" There's not much need for a new leader unless the old one dies, ya know...
    • The 20th Anniversary DVD set prominently shows Hot Rod opening the Matrix on the inside cover art. This literally happens in the last scene of the film. And while all the other chapter titles are deliciously subtle, "Megatron Transformed" might have been playing its hand a bit too much.
  • This trailer for VeggieTales: God Wants Me to Forgive Them?!?!, shows Junior doing exactly that at the end.
    • And the trailer following it for Dave and the Giant Pickle also spoils that the titular pickle is defeated at the end.
    • Along with the trailer for Josh and the Big Wall stating that "the walls will come tumbling down".
  • The Comic Con trailer for the Season 2 opener of Wander over Yonder revealed the episode's twist that Lord Dominator is actually a woman who talks like a ditzy teen.
  • Promos for the second season premiere of X-Men blatantly spoiled that Morph was back from the dead and now evil.


How well does it match the trope?
