Once shiryu's power is fully shown I swear many will be begging for their favs to be in the same sentence as the janitor because of how ridiculously OP he will be.
Clear clear fruit Awakening into void or nothingless + Overflowing Ryou + Adv CoC (the trait any n2 of legendary great pirate have) + possibly 2nd Devil fruit + CoO killing there is like at best 5 character at best who can overcome that counting Joyboy, Ryuma and Imu.
Shiryus clear futur as the most Powefull powerhouse is the most visible thing in this toon manga imo.
Even Roger look bad against Garp and couldn't land a clean hit yet some downplay shiryu cause he got hit and coughed blood as if it's the end for him and want to fault him for that.
Oda used garp to simultanuously hype shiryus AP and also his endurance by using the charater who pocess the highest punching strenght for not getting done instantly after garp enraged got a serious hit on him.
If garp can't put shiryu down with a clean hit when shiryus dropped his guard what hope does most top tier in the verse have unless they have Akainus lethality or mihawks cutting strenght.
When you add nothingless (awakening) then even akainu doesn't stand a chance now.
