Tbh, this is why i like Mihawk, He literally does nothing
He just sits there just like All Blue or Laugh Tale or Rio Poneglyphs, a Peak on a Mountain that very few dare Climb
And every time a New Character appears or New Feat is shown or New Haki or New Weapon ... etc
They just want to convince themselves that this is "Beyond" what Mihawk Accomplished or is same but was done more Easily
Only to realize that it's still not the case
We are literally in a Point in Story where Warlords are Removed & almost all of them were Defeated at least once, Three Emperors are Dead, Admirals are looking like Mere Soldiers at this Stage, We've seen Signature Attack of Roger, Shanks & Garp, their Bounties revealed, We literally know more Backstory about Imu & Dragon than Mihawk, We've seen probably every Race, We've witnessed Vegapunk's Best Inventions, We even know more Ancient Weapons more than Mihawk lol
And yet, Mihawk still "Reserved"!
Aside from Final Villain who isn't Introduced yet, you should stop expecting to see anyone with Greater Sword or Haki or Strength or Speed or Sword-Style or AoE or Lethality ... etc
