Mihawk's sword has King's haki
Zoro's sword has Oden's haki
Clear Mihawk and Zoro parallel, foreshadowing to Zoro becoming WSS
Also confirmation that King>>Oden
Roger≥Primebeard>Oden that means King>Roger and because Zoro>King it's Zoro>King>Roger≥Primebeard>Oden and also means that Zoro already surpassed Mihawk in the manga. Fraudhawkbros literally in the mud
