While many anime series are adaptations of established manga series, some original anime series have touched the ranks of extreme popularity and success. These include timeless masterpieces such as Cowboy Bebop as well as more recent original anime series like Darling in the Franxx.

Although the quality of original anime shows varies widely, there are some whose quality meets, if not exceeds, their popularity. Original anime series such as Psycho-Pass and FLCL are living proof of this claim.

Here are the top ten original anime series of all time.

Kicking off this well curated list is Angel Beats!, a series which is set in a supernatural high school, serving as a limbo of sorts.

The series follows Yuzuru Otonashi, a boy with amnesia who awakens here to find himself thrust into a conflict between two groups, initially choosing a side in the fight. The series follows their adventures throughout this conflict and beyond, making for an incredibly touching original anime series which is praised by many fans.

Meant to be pronounced as “fooly cooly,” FLCL has been described by its viewers as more of a fever dream than an original anime series. The story follows protagonist Naota Nandaba, a 12-year old boy who lives with his widowed father and grandfather. His life is somewhat normal until he runs into, or rather is run into by, Haruko Haruhara.
