Fujitora.
He and his colleague Ryokugyu got introduced postskip from literally nowhere and in Fujitora's case,people place him near Kaido and the emperors just because he can lift objects and throw at it people. ..yeah impressive right? The same people who would've never accepted that some unknown guys in the military could be as strong as the C3 admirals preskip,are now willing to bend For fujitora because he got the admiral title.
He got bandaged after Reverie where they clashed with the Revolutionary Commanders but yet again fujitora got a pass because he "supposedly" was restricted due to location,when
1)The revolution commanders were just as restricted as they couldn't afford to go all out and harm the kings and queens of the world from whom they need support against the World Government
2)Marijoie and Pangea Castle was shown undamaged indicating the scale of the battle wasn't that great,yet fujitora was bandaged.
Fujitora has yet to show how he deals easily with Fm characters as kaido oneshotted one(luffy),but sure Fujitora is near Kaido
Koby:People have absurd expectations from him like saying he is the second coming of Garp because he is under him,or that he will be a threat to luffy come Eos,as if luffy was going to be stagnant and waiting for him.The same people who say Zoro is not and will not be comparable to luffy are the same saying Koby will rival luffy and be stronger than Zoro, once more delusional.
They have already set themselves with huge fanfictions like Koby defeating Hancock and be promoted to vice admiral and then be a major player at the final war...like if Oda really intended for Koby to be that strong that fast,wouldn't he introduce Koby as at least a rear admiral,if not a vice admiral postskip? Koby is surely grossly overrated
Roger:Never called World strongest Man but just great pirate yet everybody bends over him to say he was the strongest when that literally never mentionned.His supporters were also quick to say Wb had no title in the Oden flashback to say Roger was stronger due to his Great pirate title,yet when we bring in the Wb being WSM before Roger's death, they quickly dismiss it.
Garp;Being the Mc's grand father is supposed to put him on a pedestal,he is called Strongest Marine ever by his fans despite that being never mentionned in the manga.He is called hero of the marines for having teamed up with Roger pirates to defeat The rocks,yet somehow Garp always gets all the credit with his buddy Roger ignoring they were other people with them.
The same Garp had to train to finally defeat Chinjao 8 years after Rocks as per the recent One piece Magazine,but yet Chinjao is trash and Garp is a God who soloed half of the Rocks..
Garp is called Roger's equal when all we have is some vague "we almost killed each other many times" and people say he is stronger than Marineford Wb despite the latter being known as the WSM.
