How does Killer land Sonic scythe while King is in the sky?
In cqc,King demolishes Killer since he is overwhelming Zoro who oneshotted killer when he went 3 swordstyle.
King is not Hawkins.
How does King hurt Killer while on sky? With his fire projectiles?
You're underrating Killer CQC skills, and you're also bringing Kamazo armed with 1 random scythe vs Zoro with 2 of his personal swords + a random scythe
If you think King would have already defeated Killer by now, you're delusional.
Killer's mobility is far better than Zoro's.
Killer would not be disarmed like Zoro was.
Killer probably can't handle a prolonged CQC battle with King cause Zoro is physically stronger than him and is being overpowered by King right now, but can focus more on dodging/spinning around and land Sonic attacks when King is in range.
Killer has other ways and approaches to fight King and can logorate him slowly.
