Oda made a lot of intentional parallels between Zoro and Luffy during the Wano Arc!

Both Luffy and Zoro represent a different aspect of Oden

Meeting the people of Wano

Both have experienced the hardships Wano has dealt with

The Battle of Onigashima

Both unlocked Advanced Conqueror’s Haki

Other Parallels
