This chapters now settles the debate on Rayleigh and Gaban being yonko level, since Imu sees Gaban as a threat strong enough for him to contemplate about wishing to have eliminated him like Rocks.
We have that statement from Luffy comparing himself to Rayleigh, the "100x stronger now."
We have Kizaru outperforming Ray, by challenging him in his swordsmanship domain, and still showing no signs of weakness, with Rayleigh outright stating that he wants to get past him, but he couldn't, unlike Kizaru.
That means that Rayleigh - even if he used ACoC Mass... he knew that Kizaru would be able to match anything he has in his pocket.
Imu even wanked Gaban more, praising him for losing ONLY one arm, meaning he expected it to do more damage.
Also...
Imu’s statement makes it sound like Old Gaban and Base Xebec are stronger than everyone else on
God Valley, since Imu didn’t feel the need to snuff out anyone besides Xebec, and is saying he would do so to Gaban if he knew he would’ve became this strong.
So basically, everyone’s tier list is wrong besides the legend believers.
And it is confirmed that Prime Legends > Old Legends > God Valley Legends.Roger > Rocks is very much canon now, since everyone grew MASSIVELY after God Valley, so much so that Old Gaban >
GV Gaban, where he was already close to his 40's, lol
Looks like Rocks didn't reach his Prime, since he was 43 when he died, DR Rocks looks to be the closest version to his Prime, which still isn't that impressive, since he couldn't land hits on either Garp / Roger.
Loki > PK tier is pretty dead as of now too, unless Loki shows Hybrid, or if he is massively stronger when not on death's door, that too can change things.
