-->-- '''Joseph Joestar''', ''Manga/JoJosBizarreAdventureBattleTendency WebAnimation/ButReallyReallyFast''

* This is avoided in the opening of ''Film/StarTrekIIITheSearchForSpock''...but there is an extra long pause between Creator/WilliamShatner's credit and [=DeForest=] Kelley's where Nimoy's name would normally appear. In fact, the name would appear during a moment when the screen goes white, and one could imagine Nimoy's name "appearing" in white-on-white.

* ''WesternAnimation/TotalDrama'':
** 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.
** The leaked theme song for ''World Tour'' confirmed Ezekiel's participation in the season.

* ''WesternAnimation/{{Hilda}}'': The season 1 opening sequence features multiple characters that would not make their debut 'til later (sometimes even as late as the second last episode). Jorgen, the Great Raven, the Vittra, a ghost, the Black Hound, Tontu; they're all there from episode 1.

** Volume 1: Cinder, Emerald, and Mercury appear in silhouette in the opening, despite not making their proper debut until the very last scene of the volume.
** Volume 4: The previous volume had ended with Blake running away alone, and Volume 4 starts off with her still travelling alone. However, she is stalked by a hooded figure until she finds out who he is. The opening credits, however, reveal from the outset that Sun is travelling with her, making the identity of the hooded figure easy to guess.
** Volume 7: When a new volume airs, the opening credits are placed after the first episode but in their correct place at the beginning of each subsequent episode. For Volume 7, the creators warned the fandom not to watch the opening credits before they'd watched the first episode due to there being a very large spoiler in them, namely [[spoiler:Penny coming BackFromTheDead]].

* Creator/StephenieMeyer managed to spoil ''Literature/{{Twilight}}'''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.

* [[EnforcedTrope Enforced]] with Film/{{Zardoz}}. Arthur Frayn's BreakingTheFourthWall opening monologue where he literally explains the plot of the movie was added by Creator/JohnBoorman after test audience found the movie incomprehensible. [[WhatDoYouMeanItWasntMadeOnDrugs Not that it helped much]].

* The third chapter intro for ''Webcomic/GastroPhobia'' spoils both [[ShapeShifting Mania]]'s introduction, and the appearance of her human form.

* ''WesternAnimation/{{Amphibia}}'': The opening sequence for the third season spoils the ending of the previous season, wherein [[spoiler:the show shifts locations from the titular Amphibia to Anne's hometown of Los Angeles back on Earth]]. The sequence also reveals that [[spoiler: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 [[spoiler:her apparent death]] instead. It also shows [[spoiler:Andrias' robots flying through the skies of Earth, indicating that his invasion was [[CantThwartStageOne going to get through]]]].

* ''WesternAnimation/{{Amphibia}}'': The opening sequence for the third season spoils the ending of the previous season, wherein [[spoiler:the show shifts locations from the titular Amphibia to Anne's hometown of Los Angeles back on Earth]]. The sequence also reveals that [[spoiler:Marcy is still alive]] before the show itself does, 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 [[spoiler:her apparent death]] instead. It also showed [[spoiler:Andrias' robots flying through the skies of Earth, indicating that his invasion was going to get through]].

* ''Literature/MyBrotherSamIsDead''. Guess who dies at the very end of the book.

* ''Literature/TheyBothDieAtTheEnd''. And they do.

* ''Film/SavingPrivateRyan'''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.

* ''WesternAnimation/PrincessNatasha'': Oleg doesn't appear before the third episode but the intro reveals his role in the cartoon ever since the first episode.

* In ''WesternAnimation/MasterRaindrop'' 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?

* ''Webcomic/GrimTrigger'': Volume one's opening sequence spoils Tage and Hunter working together. The first two credits also spoil Lodin and Proxy joining them.

* TheMockbuster ''[[Film/ParanormalActivity 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) [[KillEmAll hung herself too]]. The remaining 87 minutes of the film are ''[[AntiClimax pointless]]''.

* The first season of ''Machinima/RedVsBlue'' always had Tex in the opening, even if it takes ten episodes (released over two months) for the first appearance. At least it hid [[SamusIsAGirl another more important thing]].
