Every Current Yonko have Two Superiors that He doesn't wanna take Orders from,
Luffy got Dragon & Garp as his Family Superiors, One chose Marine & Other chose Revos but Luffy chose One Piece (Pirate),
Buggy got Mihawk & Crocodile as his Business Superiors, One chose Power & Other chose Wealth but Buggy chose One Piece (Fame),
Blackbeard have Three Skulls, We all know what that means,
Obviously Shanks will follow same Pattern, He has Two Superiors whom He doesn't wanna Follow because of One Piece,
Wait until you find out that Shanks, just like BB, is a triplet!
Glad there is Someone who gets it.
It's another Moon Story (Just like what Enel saw in his Cover Story), just replace Shandian/Skypiean/Birkan with a Trio from each Yonko.
