Bleach, Hunter x Hunter (2011) Recommendations
The characters in both shows are the kind that pull one along in the story, wondering what will happen to them next.
it may seems like a pretty bizarre recommendation and i don't know what to mention besides a similar genres, but both Yoshihiro Togashi and Tite Kubo was heavily inspired by Masami Kurumada's Saint Seiya and it's clearly shows. they both feels really similar, but without copying eachother.
Both series are long running (lots of episodes) series that center around action and fighting. The main characters are very good and the stories are very profound. The powers of the characters are very well thought of and become even more epic as the serie progresses. They will have you drop your jaw when you see the epic battles.
Bleach is very similar to hunter x hunter , instead of "Nen" it is spirit energy and the main characters are slightly older.
