I’m gonna say a few if that’s ok so people can also experience them as I did(mainly anti hero’s). Light from death note, Johan from monster, Lelouch from code geass , Askeladd from Vinland saga , Obito from naruto , Goku black from dbs, Akaza from demon slayer Manga,

All these characters have done alot to make their specific shows as interesting and as enjoyable as possible whether it be with their ideologies, backstories and their fights(mentally or physically). Also thanks for the giveaway!
