Zoro's character theme is his association with dark or evil "god's" like enma, kill of hell, ashura,shinagami. Their will probably be more.
Edit: More like... Amatersu, susano, izanagi, izanami etc... Pretty much most of the names from Naruto but since oda wouldn't like to use the same names like how he changed Sanji name that was originally supposed to be Naruto because it was being used by other series oda decided to change it.
Amatsu-Mikaboshi (天津甕星) is the God of Evil, Chaos and the Stars to the followers of the Shinto religion in Japan. He is not actually an Amatsu-Kami but a primordial being who was imprisoned in Yomi, the Shinto underworld, for all eternity.
Or
Futsunushi-no-Kami
God of swords and warfare
