Zoro has got poor reflexes, the worst of all the supernova. This has not changed. All he has got is attack power.
Headcannon does not change the fact that his feats are bad
That does not mean anything with his poor reflexes, mobility and agility.
This is why Sanji and fast fighters are a bad match up for Zoro. He cannot even hit kaido at all point blank range. Needing law for support 24/7 unlike the other supernova whi are quick and agile.
I'm going to get a lot of use out of this.
Zoro has poor speed and reflexes?
Tell that to:
- Kuma, who's attacks where evaded by pre ts Zoro and who was also hit by pre ts Zoro.
- Hody, who hit Luffy yet was oneshot and blitzed by Zoro underwater the water.
- Hyouzou, who easily reacted to and blocked Luffy's attack yet couldn't hit Zoro with a single attack and was blitzed by Zoro when he tried to surprise attack Zoro.
- Killer, who only was able to hit a distracted Zoro who was blitzed by Zoro.
- Apoo and Drake, who was blitzed and shocked at Zoro's attack and movement speed. In a time it took them to swing their weapons Zoro had moved passed Drake, hit Apoo, and moved passed Apoo.
- Big Mom, who attacked who counter and blitzed by Zoro.
- Kaido and Big Mom, whose attack was too fast for the supernovas on the roof except for Zoro to react to. Even Luffy wasn't fast enough to evade the attack without Zoro. He just saw an attack coming with FS. Law wasn't fast enough to evade the attack with his teleportation without Zoro.
Zoro has always been a fast character. Some claim he's not because he's more of a strength based fighter than speed but his strength has never stopped him from being fast.
There many more examples of his speed. He's always been one the fastest straw hats and one of the fastest supernovas.
