When you think of anime, what comes to mind? It’s probably something along the lines of giant robots, superpowered teenagers, or cute girls doing cute things. But there’s another trope in anime that’s just as big and that you might not have considered: aliens.
In fact, when you look closely at all the different subgenres in Japanese animation, it seems like aliens in anime have been a staple for decades. They’re fighting against the heroes, they’re a source of conflict, and sometimes they even play a crucial role as supporting characters. Anime aliens are rarely green bug-eyed monsters though. Many of them look just like humans, to the point they can pass for them.
If aliens and anime are your cup of tea, don’t miss these ones! Take a look at some of the most interesting and memorable examples of the alien trope, and feel free to offer suggestions in case we forgot some worthy titles.
