Aliens are beings that come from space and do not originate on Earth. They can range from simple bacteria to complex or intelligent life forms.
For a cryptid to fall under this category, they have to fit at least one of the following descriptions:
- The cryptid has the ability to speak and confirms through its dialogue that it is of extraterrestrial origin. (Such as Indrid Cold.)
- The cryptid is generally thought to be alien or to have characteristics similar to known Alien Cryptids. (Such as Flatwoods Monster or Dover Demon.)
- The cryptid(s) visit Earth in spaceships or flying discs. (Such as Grey Aliens and Veggieman.)
- The cryptid was sighted around the same time that an alien or UFO was seen, and so is commonly accepted as being linked to extraterrestrial life. (Such as Alien Bigfoot.)
- The cryptid is an Atmospheric Beast. Atmospheric Beasts, said to dwell in the clouds and/or the Earth's atmosphere, are sometimes percieved as alien life forms. (Such as Air Rods.)
- The witness(es) that saw the cryptid claim it was, or refer to it as, an alien.
