The 20 Best Anime About Aliens

Whether they're abducting and attacking humans or opening the door to unfathomable new worlds, aliens can spice up any story - including anime! Let's take a look at the extraterrestrial beings that appear in alien anime. 

Anime aliens don't usually have gray faces or giant black eyes - in fact, many of them look a lot like humans. Examples of this include the Saiyans from Dragon Ball Z, who are so similar to humans that they can even have children with them, and To Love-Ru, where the aliens are all cute girls. But humanoid aliens aren't the only variety to appear. There are also aliens like Migi, a parasite who takes over human bodies in Parasyte: The Maxim, and Meow, Dandy's catlike alien companion in Space Dandy.
