Being the final pirate villain, will he reach Primebeard's level. If so, how? I think his crew is already really strong, defeating the Whitebeard Pirates (I'm a subscriber of Shiryu defeats Mihawk theory).
Blackbeard defeats someone (or kills Kaido) really strong. Whitebeard Jr. turns out to be Primebeard's level, and by defeating him, he's above his former captain.
