Basic Trope: The opening credits of a work ruin important plot events before they happen.
- Straight: The Anime-styled opening to the JRPG Heroes of Troperia contains a scene with a teary-eyed Bobu by a grave with Arisu's name engraved. Halfway into the story, Emperor Evulz kills off Arisu. Following a fight scene, Bobu is seen at Arisu's funeral, mourning her death and vowing revenge on Evulz, thus causing a dramatic change in his behavior for the rest of the story.
- Exaggerated: The Spoiler Opening not only reveals Arisu's death, but also the destruction of Troperville, Evulz transforming into his true form, the party taking on Cthulhu, every significant plot point in between, and even spoils several moments from the game's sequel, which wasn't even out at that point!
- Downplayed:
- Arisu's funeral is shown in the opening, however, Arisu's death is a very minor plot point and doesn't affect the overall story.
- The opening shows a clip of Arisu's funeral, however the clip is so short most viewers/players will not notice it on their first watch/playthrough.
- Bobu is seen by a gravestone, but the fact that it's Arisu's gravestone is never explicitly stated.
- Justified: The opening spoils every significant plot point from the game, but only plays after beating the game at least once.
- Inverted: The scene of Arisu dying in the opening? She never dies, and nothing even remotely resembles it in the game itself.
- Subverted: The opening shows Arisu getting stabbed through the heart by Evulz, but when it gets to that scene in the game, Arisu dives out of the way, narrowly surviving. The player assumes that the scene with Arisu's funeral isn't from the game.
- Double Subverted: ...However, at the end of the game, Arisu actually does die, and the funeral scene is the final scene before the credits.
- Parodied: During the opening cutscene, Evulz steps in, Breaking the Fourth Wall, and threatens to spoil the ending of the game for the audience.
- Zig Zagged: The opening shows Arisu getting stabbed by Evulz, a shot of Arisu's funeral, and footage of Arisu standing with Bobu at the entrance to the Final Dungeon. Sure enough, Arisu gets stabbed halfway through the story, however, she is revealed to have survived the incident later on. However, she is killed again by Evulz at the end of Disc 2, and only then is she given a funeral. However, she is brought Back from the Dead by way of an ancient ritual, just in time to reach the Final Dungeon.
- Averted:
- The opening shows a great deal of endgame scenes and a lot of environments and enemies the player will encounter, but is vague enough to not spoil a single plot point.
- The opening shows Arisu's death and funeral, however the work is a Permadeath Video Game, and Arisu's death is completely optional and dependant on player input.
- Enforced:
- The game's writers specifically stated in an interview that they wanted to avoid showing spoilers in the game's opening, but were forced to by the publisher to hook players into playing up to that point in the game.
- The arc 1 to 5 openings were unworkable for the American dub, so they simply replaced them with the final arc 6 opening.
- Lampshaded: Bobu expects Arisu to die from the moment he meets her after seeing her tombstone in the intro.
- Invoked: The opening is a vision Bobu receives from opening the Tomes of Prophecy and Fate. Bobu, having seen Arisu's death, goes to extreme lengths to save her, but eventually finds that You Can't Fight Fate.
- Exploited: Arisu doesn't die during the main events of the story, but is eventually shown dying of old age in The Stinger, and an elderly Bobu attending her funeral. All that is shown of this scene in the intro is her tombstone, and Evulz uses this fact to scare the heroes with the threat of her death throughout the game, constantly reminding them that her death is inevitable.
- Defied: The opening shows the scene where Arisu faces off with Evulz, but the narrator stops the footage seconds before the climax of the fight where Arisu actually dies, saying that he doesn't want to spoil the plot.
- Discussed: Before starting the intro, the narrator remarks that he hopes it doesn't contain any spoilers.
- Conversed: Bobu and Arisu mention this trope when talking about Show Within a Show "Troperian Dreams".Bobu: No way! I can't believe he died!
Arisu: What do you mean you can't believe it?! It was in the opening the whole time! - Implied: Arisu isn't present in the opening at all, and considering how important she is to the plot throughout the first half, players can expect something to happen to her later on in the story.
