The difference here is, we get a pretty good grasp of what Zoro's opponent can do way before their fight. This is like the first time this ever happened.
How did we get a grasp of King or mr. 1 or Kaku.
1.Kaku snuck Zoro and didn't have his fruit in their first meeting. I mean i guess you can say he snuck sanji too.
2.Mr. 1 got kicked through a building.
3.King 2 v 1 marco and Sword shot out his hand.
This is literally the norm for Zoro opponents.
When Zoro vs Shiryu starts thats when Oda is going pull out his usual crazy hype
For example
1.Kaku revealed his fruit, he adapted to his fruit quickly showing his potential, best Swordsman in cp9, best Kicks, pressuring Zoro with 4 swird style.
2. MR. 1 **** didn't do shit but got kicked out od a building. Then oda left it a mystery why the building cut open which got reveaked in Zoro fight.
3. King i would say got mlre because this was a war arc, but Oda literally held this guys hybrid, how his fire durability works(higherthan Kaido), exploding himself. Etc...
I guarantee soon has Zoro vs Shiryu start Oda going be like Omg he is from some ancient Wano clan or some BS that love blood and their endurance is insane and swordmanship. Awakening etc....
