Summary

Anime is home to many characters that are highly overpowered, especially in Shōnen anime, where each character stands as a ceiling of strength to reach for either the protagonist to beat or an antagonist to confront. Often times these characters are non-human monsters or were once human and turned into beings of unimaginable power.

Each character has their own unique powers and skills that represent strength in almost unimaginable ways, and it’s almost impossible to beat them unless an equally overpowered character shows up against them. The strongest non-humans in anime can defeat most humans easily, unless it’s Saitama, but that said, the ones mentioned here pose an existential threat to the planet in more ways than one.
