No need to be mad sempai.
Give Zoro a free shot on an unaware Ulti and Ulti is never getting up.
You mean he beat the brains outta Killer so bad that Killer is making deranged statements like Kaido being the strongest pirate.
And Killer was hardly, if any way different. The only thing different is that he had longer weapons that do not rotate.
Killer was capable of effectively replicating his acrobatic combat style that he normally uses with his mechanical sickles through his scythes:
Rotating to attack Hiyori and Tama:
Backflipping away from Zoro.
Jumping around the place while trying to find an opening to attack Zoro from:
Backflipping to fall back:
He was clashing quite comfortably with Zoro and displayed high proficiency in the use of the mechanical sickles:
Within seconds of seizing one of the scythes (a weapon that is most decidedly not a sword) Zoro was able to adapt and improvise one of his signature Santoryu techniques:
Killer has had the scythes for several days (possibly even weeks), and the scythes are much closer to his mechanical ones than they are to a sword. If Zoro can adapt within seconds, Killer should already be highly proficient given the much longer timespan he had to get used to it (from his performance against Zoro, I would say that this is the case).
Zoro on the other hand was missing his signature sword and signature fighting style. Zoro was weaker because he was missing Shusui! Yes this is true, but this is not because Zoro was merely missing a sword that he was accustomed to, but because Zoro had lost access to his signature Santoryu style. He mentioned that he doesn't feel right without a third sword and lamented being unable to show it to Ryuma:
Shusui is also not an ordinary sword. It is an O Wazamono (one of only 21 in the world) and a black blade (one of only two to be shown in the series) that boasts of hardness and is "much heavier" than normal:
The slashes produced by Shusui are much stronger than the slashes produced by Sandai Kitetsu and Wado Ichimonji, to the extent that it swallowed up the other two:
And beat the shit outta Apoo, a guy that did this to Luffy and your boy Kidd.
Her club was rattling. Zoro without a footing and in midair took a punch from a mountain.
Covered above.
Same as Franky.
Zoro trashed the squad.
