Note: This page is a stub. You can help out by continuing to fill it out other aliens we have missed from the list.

An extraterrestrial creature not in traditional myths and not native to the planet Earth.

If an alien looks more human and less bestial or monstrous, add the alien humanoid tag rather than extraterrestrial, though there are exceptions where both alien_humanoid and extraterrestrial can apply.

Keep in mind that this tag should only be added if the creature looks like an alien by twys. Do not tag this by outside information.
