The All-Out Attack. Technologically superior forces aim their weapons of war andthree legged walkers at Earth, which bravely fights back, driving them off through cunning, bravery, or just dumb luck...most of thetime.
A combination of the above, with an infiltration paving the way for an all-out attack.
Sometimes, there are good aliens that help us against the invaders; unfortunately, they tend to be much weaker and/or less numerous, since if they were equally or more powerful, the focus would be taken off humanity. Then there's theBenevolent Alien Invasion, where the invadersare the good aliens.
Often an allegory for some Earth-based conflict, either one that's happened in the past or one that people fear may happen. The Infiltration is especially popular as a metaphor for Communism.
Eureka Seven: TV series the Scab Coral in literally drove humanity out of Earth for 10,000 years (unintentional) when it arrived. It grew and formed an outer layer around earth, fooling humanity into thinking it is another planet when they settled in.

Super Dimension Fortress Macross: Is also a deconstruction of this trope; it shows what would actually happen if a vastly superior alien race (which spends the majority of the series showing restraint, gathering intelligence, and generally beingmore reasonable than the Earthlings despite being genetically programmed for war) decides that Earth is a threat.Earth gets slagged, wiping out all of humanity in a single barrage. Only the titular Macross and her crew and refugees survive

Battlefield Earth: Has two of them, one a thousand years before the book starts when the evilPsychlos took over the planet, and then a coalition of other races swoop in after humanity retakes Earth. Thought it is more of anAlien Incursion or Alien Fracas than an all-out invasion in the second case, as the alliance is more interested in leftover Psychlo plunder and selling the humans into slavery than the planet itself.

Earth is also invaded by the rapacious Posleen who conquer and devour their way across the galaxy. This invasion folds in the plans of the Darhel.
The Puppet Masters byRobert A. Heinlein: A novel made into several movies. Of course, one of the major problems with making it into a movie is that near the endeveryonewalks around naked all the time, as it is a defense against the aliens. The aliens use, if you haven't guessed, the infiltration method.

TheWorldwar series byHarry Turtledove: This is a variation: the aliens invade duringWorld War Two and this forces the warring sides tounite against them. Also, the aliens are deliberately given contemporary (at time of writing, i.e. 1994) levels of technology plus a little extra to allow them to travel between stars, rather than the usual insanely advanced aliens vs. present day humans. They are also really,conservative. Like, they've been ruled by the same dynasty fortens of thousands of years and are surprised that humans have advanced from the medieval era to the present in only a few hundred years, conservative.
Dark Skies: A series on FOX was pretty much a textbook type 2, infiltrating with parasites and (at the end) electronic implants. The point of the series was that many of the events of the 20th century were secretly part of the infiltration, such as the Kennedy assassination.
Doctor Who: Uses all three variants of invasion. The series also inverts this tropes in many future-based stories, humans are themselves the invaders. We're usually not outright malicious, but we're often quite destructive to native species, paralleling historical imperialism and colonization.
Falling Skies: A TNT Show takes place about six months after an alien invasion devastates most major cities and wipes out a large percentage of the population. The show describes a ragtag group of survivors trying to find food and shelter to get by, while avoiding murderous aliens and roving bands of outlaws and trying to survive and fight back. While the series avoids showing the actual invasion (the background is told by a child and a series of drawings in the pilot), it involves huge circularOminous Floating Spaceships appearing over major cities. They hang there for a while, but the world leaders decide not to strike first, hoping the aliens are friendly. They aren't. The ships emit powerful EMP waves, shutting down power grids and defense systems before proceeding to obliterate most major cities. They land ground troops with infantry and mechs (the survivors note that the mechs are bipedal, despite the aliens having 6 legs) that proceed to wipe out much of the adult population, while capturing children and puttingMind Control harnesses on them (presumably, to make them slaves). The large ships depart, while the invading forces begin constructing large structures in places of destroyed cities. The human survivors are forced to retreat and use only basic weaponry (rifles, machineguns, and C4), as any heavy munitions tend to piss off the aliens, and their bombers simply level the entire area.
First Wave: Presents an infiltration approach. The Gua aren't quite sure what to expect from humans and are trying to find ways to weaken Earth's defenses. Their goal is turn humans into slaves in preparation for an all-out attack.
One episode revealed that the government was secretly preparing for an alien attack, building a series of satellites armed with nukes which were set to face away from Earth.
Invasion : A 2005 ABC show is a bizarre case of the infiltration type in which the main aliens are seen only as glowing orange lights in the water, but the infiltrating "hybrids" have theexact appearances (sans scars or other non-genetic marks)and memories of the dead humans theyreplace. This makes (most of) themunaware that they are are infiltrating aliens. It was cancelled after one season, so the actual goals of the invaders are never made clear.
The Outer Limits both versions did several infiltration invasion plots.
One episode dealt with a group of people locked in bunkers completely unaware of what was happening in the world. The last thing they heard was that a fleet of alien ships was heading for Earth with suspicions that they were here to colonize. The episode ends with only one of these people alive, as he is preparing to be rescued, unaware that the invasion has already succeeded.
Stargate SG-1 The protagonists spend all their time trying to stop aliens fromdestroying Earth (and the Galaxy in general), only to end up with a Goa'uld infiltration of the NID on their hands.

"The Invaders" (1967) with Roy Thinnes as a man who accidentally sees a flying saucer land and can't convince people that we've been invaded. They use the infiltration method, altering their bodies to look like humans. Because of the year there was a lot of heavy handed storylines involving race and the youth culture.
Achron: The game starts immediately after the greatest space fleet humanity has ever assembled has been all but completely destroyed by the alien invaders. They did this despite actually being outnumbered and outgunned by the human forces. It turns out thatTime Travel actually gives you a hell of an advantage.
City of Heroes: Takes place in the aftermath of an extra dimensional alien invasion, which was hard-won and remnants of the Rikti forces still infest the world.And of course, it turns out that the Rikti are mutated humans. BUT, that leads into another possible future invasion by different aliens. The Rikti's weakness?Magic. The Shiva in Bloody Bay are the remains of aplanet-devouring entity that was destroyed in deep space but is now trying to rebuild itself by conquering Earth for its resources.
Command & Conquer 3:Tiberium Wars marks the debut of the Scrin, whose arrival throws the ongoingGDI-Brotherhood of Nod conflict into chaos and force the two sides towork together. But it's more complicated than an "All-Out Attack" example: the Scrin are trying to harvest theTiberium they seeded the Earth with, and expected for thexenoforming crystals to have wiped out the planet's indigenous population, butKane tricked them into arriving early. The Scrin expedition is actually a mining operation, not a formal army, and once they're driven back by the humans they vow to return with a proper invasion force... aSequel Hookutterly ignored byCommand & Conquer 4.
The Conduit : The game subverts this trope. It starts off with an invasion by the Drudge, a race ofBig Creepy-Crawlies. Later,it is revealed that the invaders are actually human-created clones as part of aGovernment Conspiracy.
Destroy All Humans! subverts this trope: YOU are the invading alien. Crypto utilizes both infiltration and outright military force.
Doctor Who’’: In the first chapter ‘’The Adventure Games,City of the Daleks: The Doctor and Amy arrive in London to discover it has been conquered by Daleks and have to travel back in time to stop the invasion.
Ecco the Dolphin: Both game storylines involve aliens. In the first game, the Vortex aliens have been content to just suck up critters from Earth's seas every 500 years, but after Ecco beats them, their Queen follows him back to Earth in the second game, where she and her children proceed to mess everything up. Eventually, she flees back in time to infiltrate Earth from there.Word of God has it thatit worked, but not the way she wanted it to; the Vortex lose their identity as a species and give rise to arthropods. The third gameinvolves some completely different aliens called the Foe; their time travelling shenanigans actually work to change Earth's future, until Ecco stops them.
Gungrave: The "infiltration" method is used in the games.A race of parasitic aliens called "Methuselah" came to the planet eons ago and just wanted to infect all living things with the substance that the main characters know as the designer drug called "Seed". It turns humans and animals into mindless mutants subservient to the alien consciousness. It was these beings that manipulated and corrupted Harry in the original game, provided the technology that created the Necrolization Project, and gave Garino, theBig Bad ofOverdose, power beyond imagination. Garino was even planning to leave the planet to continue spreading seed.
Half-Life: Is about aliens coming through a portal to Earth, albeit unintentionally (though given the chance, the Nihilanth was more than happy to conquer, or try it anyway). The second is set in aDystopia where different aliens came through and defeated Earth.
Halo: Follows the "All-Out Attack" example, with The Covenant attacking Earth colonies before finally taking the fight to Earth. In order toprevent an alien invasion, all ships that are losing a battle are commanded to wipe their memory banks andself-destruct, denying the aliens knowledge of human colony locations, as well as Earth. In the end the Covenant find Earth anywaythough they were looking for something else, but this particular strategy allowed humanity to fight for years, when otherwise they would have been defeated in weeks or months.
Iji Starts six months after thealmost all-out attack has succeeded. Then looms the danger of areallyall-out attack.
Mega Man Star Force : In the game, with interesting takes on the infiltration variation. In the story, alien life forms, calledFM-ians, must fuse with humans who are very lonely thru manipulation in order to attack other people. This is because being energy waves they have no physical form and thus can't harm physical beings under normal circumstances. They can't even beseen normally. Fusing with humans allows the FM-ian to materialize and thus cause physical harm. They can also disrupt electronic devices or if there is enough electromagnetic energy being emitted, turn peopleinto energy waves to attack them.
Kid Hero Geo Stelar and a renegadeFM-ian, Omega-Xis, merge into Mega Man to defend the Earth from the FM-ians who, in turn, attempt to draw the pair out in order to defeat them and reclaim an item Omega-Xis has to unleash theirDoomsday Device on Earth.
Metal Slug 2: The Mars People arriveWar of the Worlds style aliens who attack using flying saucers. When they're driven off, one of them impersonates Morden and tries to use the Rebellion Army as a weapon inMetal Slug 3. Once that's uncovered, the heroes attack their mothership and destroy their leader, Rootmars. Properly chastised, the Mars People become a bit more peaceful, and serve as allies in the sixth game to fight an invasion fromBeneath the Earth that considers them snack food.
StarCraft: the Terrans are facing two invasions: theZerg andProtoss. The Zerg favor infiltration (infestation) as a way to soften up targets for the Swarm. The Protoss, on the other hand, employ a range of tactics, from "shoot missiles at it" through "shootmore missiles at it" past "throw in lasers for good measure" and on to "screw it, let's juststerilize the planet". Notable in all of this is the Battle of Tarsonis, where the Zerg, Protoss, andTerran rebels all try the All-Out Attack on the poor planetat the same time. The Protoss were not as much invading the Terrans as they were containing the Zerg who would then perform an all out invasion on the Protoss.
Universe At War: Earth Assault: An all out attack, In a subversion, humanity fails utterly at repelling the invading Hierarchy and are reduced to bit players, forced to watch as a race of mechanicalLaser Guided Tykebombs arrive on Earth and theancient Atlanteans awake, both species intent on bloody revenge against the Hierarchy for crimes committed against them in the past.
X-COM: The various aliens in the game series are generally set on utterly destroying humanity. The infiltration method they attempt in the first game was merely a tactic toward the goal of total destruction.
The Inexplicable Adventures of Bob: Subverted, where the Nemesites have legally owned Earth since before mankind even evolved. Until we develop good enough technology to leave Earth, they don't particularlycare whether or not we know they own the planet.Space Pirates do attack Earth once, not to conquer it but to randomly steal stuff. Nemesite Princess Voluptua comes to stop them, informing them, "Earth is anature preserve, you feebs! This isn't even piracy--It'spoaching!"
Ben 10 Alien Force first season finale climaxed with the Highbreeds beginning their planned invasion of Earth. Oddly enough, they so much as fought off asconvinced to stop when the heroes learn their invading due to being aDying Race whose genetics won't let them repopulate. It isn't until Ben uses the Omnitrix to mix various alien species with their own, saving them, that they call off their attack.
Futurama: Happens from time to time. To paraphrase a Futurama comic:
Fry: So what, Earth gets invaded twice a week. It's how I remember to brush my teeth.
The professor actually looks forward to them. According to him, the last invaders made all the smartest humans "pair off and mate continuously...oh yes."
Invader Zim: the show is about an alien using the infiltration method.He's really bad at it. However the Irkens are really good at what they're doing, no matter how bad Zim is. We've seen them successfully take over several planets and they seem to run a galactic monopoly that can't be challenged by any other being in the Universe (to our knowledge).
Jimmy Neutron: Three separate times. The first time the Yokians arrived to Earth they stole every adult in Retroville (except Miss Fowl) only to take them to their planet. The second time they arrived on Earth they successfully earned everyone's trust and tried to kill off all the adults once more. Then there is Grandma Tater's, who's apparently one of many similar aliens that take over planets using hypnosis.
Darkseid invades the Earth in theSuperman: The Animated Series episode "Apokolips... Now!" The good Alien role is filled by his heroic son Orion, who threatens a counter-invasion from New Genesis, forcing Darkseid to retreat.
He does so again in "Legacy", using a brainwashed Superman as a weapon.
Justice League: The very first story arc, "Secret Origins", sees the Justice League come together for the first time to combat the White Martians, shapeshifting aliens. Initially, the aliens infiltrate society to undermine Earth's defense systems, then they begin their All-Out Attack. The Good Alien role is filled byJ'onn J'onnz, thesole survivor of a Martian civilization that these invaders had destroyed centuries ago.
The Season TwoGrand Finale "Starcrossed" sees the League nearly destroyed by another invasion. TheThanagarian infiltration was far more effective, because they had aMole in the Justice League itself, providing them with the information to neutralize its members. These invaders initially present themselves as the Good Aliens, claiming that they're fortifying Earth to defend it from their enemies; thereal Good Alien turns out to be their Mole,Hawkgirl, who learns of their true intentions for Earth and isunable to go through with it.
TheJLUGrand Finale "Destroyer" has Darkseid leading the forces of Apokolips on an All-Out Attack on Earth. The League is forced totemporarily team up with the remaining members of the Legion of Doom in order to fight them off. Utimately,Lex Luthor saves the day, offering Darkseid the Anti-Life equation he had been searching for his entire life - but when Darkseid touches it, both villains are apparently vaporized.[1]
Kim Possible: TheGrand Finale had the previously once introducedScary Dogmatic Aliens invade Earth for rather no real reason at all. All they did was send inHumongous Mechas while the two aliens just sat and relaxed. Rather than an "official" government-backed invasion, it appears that the whole attack was simply a private vendetta against Drakken/Earth on the part of Warmonga.
Little Audrey cartoon "Dizzy Dishes": In Audrey's dream there are alien invaders attacking with a disintegrator.
Teen Titans: In the episode "Troq".Gets inverted The Titans launch a preemptive attack against therobotic, alien menace on their own, alien planet. Our heroes succeed in killing the entire planets’ population off! Then they tell off the guy who brought them there for being aracist douche.
The Simpsons did this many times with Kang and Kodos. The best was prior to the 1996 presidential election where they kidnap Clinton and Dole and take their places (infiltration method). In the end they are discovered but still win because they have both major candidates and "It's a two party system. You have to vote for one of us." Someone suggests voting for a third party candidate: Alien: Sure, THROW your vote away!" In the end they are our rulers.
