this thread is just a theory -
so we know shanks sacrificed his arm for the new gen
it was to show luffy what it means to be a pirate
but ofc a sacrifice means something
shanks and blackbeard are destined to clash in the future
with shanks monitoring every step of black beard and being very cautious of him
sooner or later , the inevitable clash will come
and if their will be a winner
it will def not be shanks since bb is supposed to be put down by luffy
who also wants to surpass shanks
luffy's best way of surpassing shanks and his crew will be by beating the winner of that clash
now, it has been portrayed that shanks has lost strength after he lost his arm
thus mihawk stopped dueling with him since shanks killed off his potential of growing any stronger and surpassing mihawk
blackbeard was alrdy able to scar 2-armed shanks
imo he was able to scar shanks with the same cause on why he has 2 devil fruits
blackbeard is hiding something within him
something which brings out a secret strength capable of scarring even shanks
but this time shanks will be even weaker than that
his cause of downfall in the fight will be his missing arm
and then the very reason why he gave up that arm is gonna beat blackbeard
closing all of their rivalry and shanks's goal perfectly
