I wonder what Oda's cooking with the obvious Zoro-Loki mirroring.
Both were crucified during Luffy's first interaction with them, and Luffy wanted to set them free. He asked both to join his crew. Oda even comments on the crucifixion in the author's notes for the first Elbaph volume (111).
Both refused invitations from organizations: Baroque Works for Zoro and the Holy Knights for Loki. Mr. 1 and Miss Doublefinger are kind of like Shamrock and Gunko, with Mr. 1 and Shamrock both being the No. 2 in their respective groups.
Then there are the demon-like traits they share and their underworld connections. And in Chapter 1153, we have an 8-legged horse named Asura. The Zoro-eye theories are becoming stronger than ever.
