i have just finished the war between the white beards and the navy. and then white beard dies getting killed by blackbeard so then black beard takes his devil fruit power sooo i don't understand how black beard could possibly be defeated now it's just immposible. when he gets used to his new devil fruit know one will stand a chance maybe not even shanks or dragon who are at the same level as white beard. Tremor-Tremor Fruit + Dark-Dark Fruit= INVINCIBLEU_U
