Invasion of Falls
is a Gravity Falls/Invader Zim crossover fic by LordStar8045.
Dib thought he had seen the last of Zim after the Florpus incident. However, in the strange and wondrous town of Gravity Falls, Dib would find not only his old nemesis but other crazy things that would drive him up a wall.
Invasion of Falls contains the following tropes:
- Accidental Hero: Zim destroys the monster transformation amulet because it's a threat to him personally, and ends up praised for saving everyone else from it in the process.
- Baleful Polymorph: During the Sumerween arc, a magical amulet changes all the core characters (and Wendy's friends) into various monsters. Zim and GIR, meanwhile, are turned into humans.
- Gamer Chick: Gaz, as usual, has her eyes pressed against a gaming console.
- Green-Eyed Monster: As Wendy teasingly points out, Pacifica becomes this regarding Dipper.
- How the Mighty Have Fallen: How "mighty" Zim was beforehand is debatable, but after the Membranes and Pines manage to catch him, he's reduced to indentured servitude in the Mystery Shack.
- Hypocritical Heartwarming: Mabel states that since Gaz is her "frenemy", only she gets to insult her.
- Mistaken for Gay: Gravity Falls' local gossip newspaper sees Dib and Dipper interacting and jumps to the conclusion that they're dating. Pacifica actually believes this, despite Mabel trying to explain that Dipper doesn't swing that way, only for Gaz to rile her up by implying it's true as a form of Revenge by Proxy.
- "Not So Different" Remark: When Dib is arguing with Zim about the fact that his leaders, the Tallest, aren't coming because they are dead and the whole Irken Armada sucked into the Florpus Hole, forever lost thanks to him:Zim: YOU LIE! What would a failure who can't even convince his own bigger failure of a species to recognize your 'greatness'?Dib: ...So are you.Zim: What did you say to me?Dib: You and I are the same… (Dib starts giggling crazily) Guess we are both failures to our respective species, HAHAHAHAHAHA!
- Our Dragons Are Different: When confronted over the monster transformation amulet, Iggins uses it to turn himself into a dragon.
- Parents as People: Professor Membrane, after the events of the Florpus, has been making more of an effort to be more involved in his kids' lives and sends them to a summer camp in Gravity Falls to get them to socialize more.
- Restraining Bolt: Ford infects Zim's PAK with nanites that keep him from using his weapons without consent.
- Seven Deadly Sins: During the "Sins and Dookies" arc, several characters are cursed with manifestations of the sins, leading to among other things Dipper lustfully kissing every girl he comes across and Wendy being so slothful that she doesn't even get up to use the bathroom. Notably, Gaz is cursed with wrath, but since that's so similar to her normal persona, she's able to control it.
- Sitcom Arch-Nemesis: Gaz and Mabel do not get along at all, constantly butting heads and arguing, but occasionally agreeing on other things like disliking other characters' stupidity. Mabel refers to the situation as them being "frenemies".
- The Only One Allowed to Defeat You: Zim gives this as the reason why he saves Dib from dragon Iggins.
- Weirdness Censor: Downplayed: While the public didn’t completely overlook the events of the Florpus, they chalked it up to some strange cosmic event.
- What the Hell, Hero?: Dipper is horrified when he catches Dib about to dissect Jeff the Gnome, calling him out for his Fantastic Racism towards nonhumans.
