''Invasion!'' was a three-part CrisisCrossover miniseries published by Creator/DCComics in 1988. (It should not be confused with the [[Series/{{Invasion}} TV series of the same name]], or any other invasion-themed series.)

An alien race called The Dominators discovers that Earth's superhumans get their powers from a 'meta-gene' and decide to capture them all to be used as living weapons with which to conquer the universe. Realizing that they cannot beat the heroes by themselves, they convince several other races from around Franchise/TheDCUniverse to aid them under the pretense that the "metahumans" were too dangerous to be allowed to exist (and taking advantage of the fact that the [[Franchise/GreenLantern Green Lantern Corps]] had, at the time, been reduced to only a handful.)

The combined might of the alien armada seemed invincible but thanks to a HeelFaceTurn by one of its own member races, it was routed. But a second threat happened when a Dominator scientist detonated a "meta-gene bomb" whose radiation rendered most of Earth's metahumans helpless. Another switching of sides--by, ironically, that same scientist--helped save them.

The series L.E.G.I.O.N. (about a mercenary group that protected the galaxy in the Corps' absence) was spun off from the crossover. It also launched the series of [[ComicBook/JusticeLeagueInternational Justice League Europe]] and the Daxamite superhero Valor (also known as [[ComicBook/LegionOfSuperHeroes Mon-El]]). (A team called The Blasters was introduced by the crossover and given a one-shot special, but never had its own series.)

!!Tropes:
* AliensInCardiff: The alien armada begins its attack by... taking over Australia.
* CaptainErsatz:
** The Khunds are pretty much [[Franchise/StarTrek Klingons]].
** The Durlans are [[ComicBook/SecretInvasion Skrulls]].
* CategoryTraitor: The Thanagarians joined mostly to capture Katar and Shayera Hol.
* EasilyThwartedAlienInvasion: Earlier attempts by various races. This one came closer to succeeding however.
* FantasticRacism: Part of the reason for the alliance was... that aliens don't like how we look. The Daxamites and Thanagarians resembled Earth's humans, but they had no genetic variance eg. they all look alike.
* HeroicSacrifice: One of the Daxamite observers for the alien alliance, who died of lead poisoning so he could reach a transmitter to tell his homeworld to throw in on Earth's side. (At the time, the Daxamite was the father of Lar Gand, a.k.a. [[ComicBook/LegionOfSuperHerioes Mon-El]]; this has probably been [[{{Retcon}} retconned]].)
* HumanAliens: The Daxamites and Thanagarians.
* {{Irony}}: Several things.
** The invaders had no idea that the superhumans were going to be used against them once captured.
** The Daxamites helping route the invasion.
** A Dominator helping save Earth's heroes (after almost killing them.)
* MetaOrigin: The meta-gene, present in some but not all humans. It grants superpowers when exposed to dangerous forces. Note that not all superheroes got their powers from it, just the majority.
** The "Blasters" team were the survivors of a group of 100 random humans [[AlienAbduction kidnapped]] to demonstrate the theory. The Dominator running the experiment expected that if they were all attacked by a firing-squad barrage, one of them would spontaneously develop powers that would allow him to survive. Instead, seven people did, including (unknown to them) former ComicBook/{{Justice League|OfAmerica}} sidekick Snapper Carr.
** The Daxamite gain powers on Earth similar to Superman's, apparently being distant cousins of Kryptonians. However they were also vulnerable to lead-based pollution, and only survived because Earth's heroes saved them.
** Some people actually ''gained'' powers (or had them altered) as a result of the meta-bomb, most notably [[ComicBook/{{Justice League|International}} manager Maxwell Lord. Several of the new members of Comicbook/DoomPatrol introduced during the Creator/GrantMorrison run were also said to have got their powers from the meta-bomb.
* NamesToRunAwayFromReallyFast: The Dominators. [[WhatAnIdiot Not that most of their allies realized it]].
* {{Parody}}: At the time, Marvel's ''ComicBook/XMen'' were situated in Australia. So they had an issue where they stopped a thinly-disguised version of DC's invasion.
* RubberForeheadAliens: Most of the alien races that weren't the Daxamites or Thangarians.
* SpacePolice: The [[Franchise/GreenLantern Green Lantern Corps]], the L.E.G.I.O.N.
* WeaksauceWeakness: Lead, for the Daxamites.
* YouHaveFailedMe: The Dominator Leaders had not told their scientist what the real purpose of their mission was. So they rewarded his invention with torture, which led to his HeelFaceTurn.
* YourPrincessIsInAnotherCastle: The invading alliance seems to be defeated by the second issue... oh, wait, gene bomb.
