>>12817046>He certaintly hasnt tried to take on the world government
He doesn't need to directly challenge them to be considered top priority; THAT'S how big of a threat he is.
This is the guy who fought evenly with the fucking Pirate King multiple times, and is currently considered the strongest pirate in the world and the closest to one piece.
He's like Dragon. Although he hasn't made a move on the Government yet, the fact is that if he WANTED to, he could probably take down a huge portion of it by himself.
The mere fact that he simply has the power to do it is enough to make him top priority.
