Welcome to the Alien Species Wiki

9,964 articles since we began

Alien Species Wiki is a website containing information on any alien creature ever imagined by mankind. From furballs to behemoths, from little green men to shades of blue, from mindless parasites to intergalactic empires. The wiki format allows anyone to freely add or edit content!

Feel free to browse the Alien Species Gallery, it is a good tool for learning the names of aliens you have only seen but do not know the name of.

About us

Canon and non-canon are both allowed here. Speculation on things not covered by official sources is allowed, as long as the article makes it very clear that the author is speculating. Fan-created species and fanon in general is strictly forbidden.

Alien Species Wiki's database currently has over 3500 Sapient Species, plus 1200 Non-Sapient Species, 800 Locations, 600 Characters and 100 Affiliations and there is still MUCH to be done.

Rules and warnings

Some important things that everyone should be aware of before editing:

  • Copy-pasting text from external sources (including other wikis) is strictly forbidden. Users who do it will be blocked immediately and copy-pasted articles will be deleted on sight. The only exception to this rule concerns a few articles shared between this wiki and our sister site.
  • It's also strictly forbidden to create empty blank pages, as well as to merge, split, rename or repurpose pages or reupload images without direct approval from an admin. Users who do any of these risk getting blocked, although some offenses are less serious than others and will be judged accordingly.
  • Fictional species are only allowed here as long as they've been featured in official, commercially-published media. Original web content is generally not allowed for this reason.
  • Articles should NOT be written in past tense, unless dealing with a creature that's officially extinct.
  • Sentience means feeling. Sapience means thinking.
  • Since this wiki deals with a lot of fiction, every page risks containing spoilers. The worst cases, dealing with major plot twists, will be marked with an appropriate template.

It is called the "calamity from the skies" or the "crisis from the sky" (空から来た厄災, Sora kara kita yakusai, lit. "Disaster which came from the sky"), or "Heaven's Dark Harbinger" by the cetra...Read More
