VC of the Pirate King (who has a bounty of 5.5 billion) is relaxedly living his life right next to Marineford/Mariejoa. They are aware he is there and they know that this person knows the full True History of the world. Yet when it comes to capturing him, Garp was like "You want the Navy to fight Two Legends at the same time?"
Luffy goes to Wano, the land where CoA mastery is common. There an old Legendary warrior in his prime sees Luffy accidentally do Internal Destruction and he says it's at a level beyond me. This person can use it casually.
At Old Age, he saves Strawhats from a Marine Admiral and what does the Admiral do? Beat this guy or capture him? Nope, vent his frustation on fodders.
At Old Age, he shows up infront of BB who travelled entire Grand Line to take Boa's fruit and had her by her neck choking and tells him to Sit the fuck down and be Humble, and what does BB do? He listens like a little kid because this person's reputation is so good.
Luffy can K/O 50,000 People with CoC?
