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

First, both Oden and Zoro have no navigational skills.

Oden met a 26 years old Toki.

Zoro met a 26 years old Hiyori.

Oden saved Toki and fainted.

Zoro saved Hiyori and fainted.

Toki treated Oden.

Hiyori treated Zoro.

Toki/Hiyori hug a furious Oden/Zoro while crying.

Furious two sword style Oden/Zoro went to claim Orochi’s head.

Orochi terrified.

Oden’s figting style has a great resemblance to Zoro’s. Just Oden using 2 swords while Zoro uses 3 swords.

Oden gave Kaido a permanent scar, something no one else has been able to do before or after.

So what’s next for Zoro? Heavily Injure Kaido? Surpass Oden? Blacken Enma?
