High tiers from Anime/Manga/Manwha/Light Novels like Son Goku, Sailor Moon, Vampire Hunter D, Sakamaki Izayoi, Pegasus Seiya, Saitama, Dark Schneider, Simon the Digger, Madoka Kaname, Altair (Re:Creators), Rimuru Tempest, Sakura Kinomoto, Naofumi Iwatani, Tenchi Masaki, Toriko, Devilman, Haruka Kaminogi, Haruhi Suzumiya and Mori Jin should at the very least be consider Herald level, due of them having cosmic level feats/scaling/statements far beyond the planetary range, and they can be potentially higher (as someone like Simon, Tenchi, Haruka and Madoka could be argue that narrative wise they should be put at Skyfather level).
Mid tiers like Monkey D. Luffy, Yoh Asakura, Ryūko Matoi, Alucard (Hellsing), Lina Inverse (without Lord of Nightmares's power), Saber (her regular forms), Edward Elric (only via alchemy), Kenshiro, Cutie Honey, Lucy (Elfen Lied), Medaka Kurokami (only physically), Ichigo Kurosaki, Naruto Uzumaki, Natsu Dragneel, Asta, Arcueid Brunestud (her regular forms), Izuku Midoriya, Shō Fukamachi, Dio Brando, Yusuke Urameshi and Cyborg 009 should be instead Metahuman level which could be everything from be able to destroy Earth to be able to bust just a town.
Low tiers like Golgo 13, Lupin III, Rally Vincent, Lelouch vi Britannia (only physically, higher with his mecha), Revy, Ryo Saeba, Conan Edogawa, Jotaro Kujo (physically only, without counting his Stand), Accelerator (only physically, vectors can put him at much higher), Guts, John Doe and Motoko Kusanagi instead can be easily treated as Street level since lore wise they are more "grounded" characters similar to Batman and Captain America, even if feats wise they are physically stronger than Real Life humans.
