Teach (or some of his crewmates)will defeat defeat:
Law, one of the 3 billion pirates credited with defeating the Kaido and Big Mom alliance.
Garp, the legendary renowed hero.
Shanks, a man who got 4 bil within six years of being an emperor, a former crewmate of Roger, clashed with Mihawk in legendary duel(s), and has connections to the Gorosei.
And most likely other strong and notorious characters
His EOS bounty will be massive. My personal hope is that he ends up with a 6.66 billion bounty, but I think he'll definitely end up above Whitebeard's bounty. Thoughts on what his EOS bounty will be?
