No Hawkins actually had the upper hand. Zoro actually got hurt by nails. Hawkins lost a puppet but was fine
Killer was both emotionally hurt and physically nerfed by his weapon but still one shot zoLo.
Drake was bleeding from the head from both queen and whoโs whoโs sneaking him. Zolo was struggling with gifters.
No.
Hawkins lost three dolls to Zoro, which means he died three times against Zoro. Hawkins just slightly injured Zoro because the was trying to deflect all the nails because he was protecting everyone instead of evading it.
Hawkins was using a powerful scarecrow which is the equivalent to Luffy using his G3. He uses his DF power to create a straw creature large in size to produce more power, similar to how Luffy increases his size to gain strength/power. Increase in size/mass equals to increase in strength/power. Plus he used a good card to push his power (scarecrow) beyond its limit. Zoro oneshot it using an average attack.
Zoro bested (defeated) Hawkins and the manga says the same.
Killer was never nerfed. Eating a bad DF doesn't make you mentally or physically weaker. He was fighting to protect his captain and in One piece that makes you stronger. We saw him crying after he was captured along with Kid. He was crying because he failed his captain and he believed they were going to be executed.
Killer was using weapons very similar to his normal weapon and because of that his fighting style never changed. His fighting style is similar to Sanji's. He's a fast and agile mobile fighter that uses momentum to increase the strength/power of his attacks. It still took a distracted Zoro for Killer to hit him. Yes, Zoro is that fast.
Zoro blitz and oneshot Killer while injured and using a weapon he's never used before. Zoro didn't fall until after all his battles were over. Even then the manga focus on his stomach right before he falls which mean Zoro falling had to do with stomach problem. The manga showed us that he was starving at the time eating poison food days before that.
Who's who didn't attack Drake. Queen was the only one showed holding a bloody sword while Who's who sword was in its sheath. That implies he never attacked Drake. Drake is an ancient Zoan so he will have impressed the recovery ability.
Zoro never struggled against the gifters. There was just a lot of opponents he had a fight. Zoro's injury came from Queen chomping down on him in his mouth and spitting down from a high altitude and with so much force it caused an impact when he hit the ground. Since Zoro doesn't have a DF to increase this recovery if Drake is in a weaker state than Zoro that makes Zoro look even more impressive.
