A response that makes no sense.
KOH is not a small power-up. It is huge.
Zoro just casually one-shot Lucci in base. So there's not a chance that Lucci could contest with KOH for even a second, because KOH Zoro bodybags base Zoro.
This means that Zoro never used KOH vs Lucci, which is obvious as the art shows there's not black lightning on all three swords which is a prerequisite for KOH - plus, the very next chapter, Zoro was seen with Wado Ichimonji sheathed so he exited Santoryu.
You have no leg to stand on here lool - base Zoro got serious for a single page and just embarrassed Lucci even worse than G5 Luffy did. Posting panels of random skirmishes from before Zoro was serious and even used so much as a named attack isn't gonna change that lmfao.
