That chapter is titled after Killer calling him the strongest pirate.
It's literally the same as the chapter referring to Aokiji as "strongest combat force" because Robin said he was one of the strongest combat force of the WG
There's many cases where a sentence said in a chapter ends up in the title without being contextualized
Yes he was WSP, WSC, WSM
That's why the chapter is names after that fact.
Admiral Kuzan is indeed WG strongest force as Admirals are all named their strongest fighters.
Why isn't Akainu getting hyped as WS? When Kaido is around or even now?
Rumour or total fact, why is it only Kaido having this hype in sbs , novels, manga ,volumes and magazines ?
Why is he the only one beside WB to get such WS hypes and portraayal then?
Oden, BM, would hype someone who's not that powerful
Kaido is the peak of combat ,only Luffy surpassing him at EoS . Imu & Teach will be stronger due to hax abilities.
At least Kaido's strength is respected by Navy, WG, Yonko, SNs , everyone to warrant WS claims
Where is Akainu?
