Meanwhile, a certain pirate received a $100M bounty after defeating a former schichibukai, who previously had his own bounty of around $130M.
Luffy single-handedly defeated two schichibukai thus far, and could've defeated Hancock as well if they ever actually fought. At this point, I don't think Luffy is even ready to enter the new world yet, and you're indirectly implying he's stronger than 95% of Whitebeard's crew.
