Aliens and Monsters

They look all the same to me. Charge the main cannon!

"He got an e-mail from his brother that said that aliens and monsters were attacking his place!"

— Half-Life: Full Life Consequences

The integral part of the Monster of the Week episode. They are strange, scary, and expendable. Some are different than what you'd expect them to be.

Of course, we can have alien protagonists and monstrous supporting characters; but the difference here is that, within the ethics of the shows that use them, it's okay to kill the specific threat-of-the-week version (which is usually a distinct species.) There is no need to deal with complicated intricacies of interstellar diplomacy to negotiate with aliens, consider ethics of advancing mankind via genetic engineering when dealing with mutants, and listen to a vampire's tragic past to understand him better. This time, there are no long term negative consequences to deal with either using what humanity does best.

Violence.

In short, this trope is for a specific example of Black and White Morality when a non-human antagonist (and, likely, his entire species) is Always Chaotic Evil with a shallow, handwaved, or Played for Laughs justification. Different from Aliens Are Bastards, in which the reasons for hostility can be elaborate and well-explained, and often the subject of much debate and comparison to conflicts among humans.

Not to be confused with the DreamWorks movie Monsters vs. Aliens.

Examples:

Anime and Manga

• In Gantz, the hunters are forced to fight a wide variety of enemies from this category.
• At the beginning of Bleach this is presented as how the situation is supposed to be, with shinigami sallying forth to take out the Hollow of the Week. After the first season things get a bit more complicated.

Comic Books

• The very first Bizarro story by Otto Binder in Superman assumed Bizarro to fall into this category, and he is destroyed at story's end. Fan letters quickly made it clear that Bizarro was much too sympathetic to die so ignominiously, and he was soon re-created by Lex Luthor.
• In DC Comics' Looney Tunes title, Lola Bunny delivers pizzas to ancient gods, Killer Robots, Fish People, and other unusual customers.

Fan Works

• The fan fiction series The Lion King Adventures adopts a Monster of the Week format. Aliens and monsters crop up often:
  • The Inque and the Vimelea are alien parasites.
  • The unnamed creatures in The Chase are vicious monsters who eat anyone who crosses their path.
  • All of the other villains are, arguably, monsters. Particularly Death and the Writer. Most other examples are metaphorical.
• These feature heavily in Calvinverse stories.

Film

• Monsters vs. Aliens features this. It's the aliens who are used this way; the monsters are the good guys we send to fight them.
• The Godzilla films feature various aliens attempting to take over the earth, often using some sort of giant monster to aid them in their quest for conquering the world (IE: Mechagodzilla, Gigan, King Ghidorah, etc).

Folk Lore

• The Chupacabra, an Urban Legend, is an alien and a monster that has been used as a menace in several TV shows and movies.
  • There is a surprisingly solid theory that the first person who spotted the Chupacabra was inspired by seeing the movie Species, which fits this trope possibly even better.
    • Species came out in 1995. People have been talking about the Chupacabra since the 1970s.

Live Action TV

• Doctor Who is king of this trope, to the point where, eventually, monsters would make their way into stories in which it has no place ('The Caves of Androzani', for example, is a thriller about interplanetary politics and the ruthlessness of unfettered business practices against a weak military and political sector, with a strong cast of interesting villains in its own right...which features an unconvincing monster in a cave because, well, it's Doctor Who, innit?). Ironically, the show was supposed to be a historical edutainment program, until the Daleks showed up in the second story and royally EXTERMINATED that idea.
• Buffy the Vampire Slayer:
  • The show had many demons of the week. Remember that one that Buffy had to beat the crap out of, while Giles and Willow cast a spell on it?
  • Inverted in an episode of Angel. Cordelia has a vision about a demon and Angel proceeds to find and kill it as usual. Immediately afterwards, he finds out that the demon was actually on a mission from the Powers That Be and he should have been helping it. To be fair, he was also misled by an untrustworthy informant who told him the demon was evil.
  • Actually, both aliens and monsters sorta appear on Buffy the Vampire Slayer. A grand total of one (supremely scary) alien appears in the entire run of the series, and its origin is supernatural anyway.
• The Outer Limits (1963) was specifically designed to have one "bear" every week, the producers' code term for aliens or monsters. One of the most popular episodes, "Demon With a Glass Hand," stuck the word demon in the title mostly to satisfy the network execs, who wanted a monster in every episode. There's certainly nothing demonic-looking about Robert Culp, and the bad guys are Human Aliens.
• Special Unit 2 is based on this trope, combined with All Myths Are True (except vampires).
• The Reavers serve this purpose on Firefly, but the trope is actually more often subverted than not, as there are no aliens and the characters are more likely to find themselves up against other humans than anything. In the Big Damn Movie, Serenity, the Reavers are revealed to be once-human survivors of an Alliance experiment aimed at pacifying an entire planet's population and had the opposite reaction to the drug they pumped into the atmosphere, which instilled such apathy in everyone else that they simply laid down and died.
• Let's not forget the antagonists in every episode of Power Rangers ever.
• In the Ultra Series, the Monster of the Week is always either a Kaiju or an alien invader (usually able to make themselves kaiju-sized). However, it should be noted that the titular Ultramen are aliens themselves.
  • In a subversion of the trope, many of the shows feature friendly or nonviolent kaiju and aliens from time to time. Although there will often be a small fight if a misunderstanding occurs, most of the friendly monsters don't die in the end (and if they do, it's always a Tear Jerker).
• Pretty much every Tracker episode.

Tabletop Games

• Delta Green is primarily a Cthulhu Mythos setting, you can encouter creatures from the mythos, Elder Tomes, Eldritch Abominations, Magic (Referred as "Hypergeometry") that might be advanced science and The Greys, which supposedly secretly control the US government in exchange of technology. Actually the Greys are created and remotely controlled by the Mi-Go so their Majestic-12 contacts would have a form they are conforable with that would not driven them to insanity upon seeing something so alien. Makes sense considering that in H.P. Lovecraft tales there was no difference between the aliens and the supernatural.
• Tech Infantry has vampires, mages, werewolves, weretigers, wererhinos, alien bugs, alien lions that fly, and few of them are as scary as some of the normal humans.
• Paranoia has included suggestions for alien invasions alongside the Giant Mutant Radioactive Cockroaches; of course, any mission in Paranoia is just a Framing Device to let the PCs betray each other, so...
• Monsterpocalypse the factions compose of 50 foot tall monsters, which include invading aliens, hungry dinosaurs, giant Gorillas, and so on...
• Warhammer 40,000: The Holy Imperium of Man preaches this about pretty much all non-humans - Eldar, Orkz, Tyranids, Tau, even Daemons: All are evil and must be destroyed, with little to no distinction made between "xeno" species. They're little better themselves, though.

Video Games

• Afraid Of Monsters has them both in the city, due to David's drugs.
• The Half-Life series, natch. Primarily featured in the first game; by the second, one of the alien species had joined our side, all the others except for the headcrabs have mysteriously vanished, and most of the enemies are human cops and transhuman soldiers working for the unseen Combine, an interstellar and apparently multidimensional empire bent on universal conquest.
• War of the Monsters features monsters being born from alien fuel, with both wreaking havoc on humanity and against one another.
• Kid Icarus Uprising has every single nonhuman living thing as an enemy. Even, later in the game, the centurions.

Webcomics

• Sluggy Freelance has plenty of aliens, demons, and vampires the cast kill without a qualm, even though they also count several aliens, demons, and vampires among their friends. Aylee called Torg out on this when he spent his time in another dimension killing the monstrous residents in sadistic and hilarious ways.

Web Original

• The Global Guardians PBEM Universe was full of aliens and monsters. It is a superhero setting, after all. One hero team actually fought Godzilla for crying out loud...
• Freaks Mutants And Monsters is a good example.
• Parodied in "The Six Monsters You'll Have For Roommates", a CollegeHumor sketch.

Western Animation

• Ben 10 and its sequel, Ben 10: Alien Force.
• Kim Possible: Considering the characters in the show, the Lorwardian invaders and the monsters made by a Mad Scientist are just icing on the cake.
• Martin Mystery goes back and forth with this.
• Uncle Grandpa has a few, including Emperor Krell in "Space Emperor", the Night Wolves from "Belly Bros.", the titular entity of "Funny Face", the two-headed dragon from "Nickname", the mummy from "Uncle Grandpa Ate My Homework", the alien cactus in "Jorts", and the cartoon monsters from "Viewer Special".
• Many SWAT Kats villains fall into this trope.
