Law never got one shotted by Blackbeard lmfaoo, he pushed the fat boy and half of his crew even when he got ambushed. Akainu was even commenting on it like it was two yonkos fighting. Reminder that Blackbeard was confident that he could have defeated even the SHP. He was gonna ambush any of the 3 crews who came out of Wano.
And forget Blackbeard, even Big Mom is a way stronger opponent than the Holy Bums. An opponent of her caliber solos all Omen-buffed HKs (minus Shamrock) combined.
