Zoro fighting with only one sword less ain't even compareable to Luffy fighting without Gear 4 lmaooo. Desperate af.
Zoro fought with 2 out of 3 swords, but guess what, Killer fought with completely different weapons. => Killer Nerf >> Zoro Nerf
After some time of equal fight, that big guy butted in which was a nerf for Zoro. But it's not even comparable to killer who was tortured all over his body, had the psychological damage of eating a smile, and with both together beeing in an extremely weak mental and physical state. Again, Killer Nerf >> Zoro Nerf.
Yet at the end Zoro only won due to stealing one of Killer's weapons and thus having a 3v1 - and after he defeated Killer Zoro also dropped unconscious himself.
You don't get it. When you look at the facts it's easy to see why Zoro was and still is levels above Killer.
There's never been any evidence support that Killer was mentally or physically weaken or broken during the battle. The bandage on his hands and head was just there to hide his true identity.
Zoro is physically much stronger than Killer. He stopped Killer from pulling the scythe out of his body by just flexing his muscles.
Zoro is much faster than Killer. Killer was only able to hit Zoro because he was distracted by a character he was ignoring and who Zoro didn't consider a threat.
Zoro blitzed Killer. Zoro didn't need to block or break through Killer's weapon to hit him. Zoro still had faster attacks. His lion song and dragon blaze attacks are two of his fastest attacks.
Zoro is a more skilled fighter and blade/edge weapon user. Zoro quickly adapted the scythe to his fighting style. Zoro performed a name attack with it and use it to defeat Killer. Killer had more experience with it and time to train with it but was never able to do the same.
The only thing that was close was their close quarters combat skills and the second Zoro used a name attack he defeated killer.
That was the most important thing about the battle. Zoro never used any name attacks/technique until the very end. As I explained when he did we saw how quickly Zoro ended the battle. If Killer, with his punisher blades, faced 2 sword Zoro again Zoro would still have all of his 2 and 1 sword style techniques at his disposal to use against Killer. He would defeat Killer was same. Zoro vs Ryuma is a excellent fight that showed how strong Zoro with 2 sword style can be.
It wasn't a double KO. Zoro defeated Killer and than moved on to fight the fox who forfeited the battle.
What's funny is Luffy passed out immediately after he hit and knocked out Doffy. Yet, nobody considers that a double KO.
