Squard was a name in the New World with just a 200M bounty.
There are two New Worlds, IMO.
The New World Yonkou Territory
And everything else.
Outside the Yonkou Crews, a 200 Million Pirate is a problem for most pirates, and most Marines. And from what we've seen, only insane pirates like most of the Supernova actually have the spine to attack the Yonkou.
Guys like Hawkins are way more common: float around a bit for a decade or so, then either die or get assimilated into a stronger crew. And even Hawkins was trying to get into a alliance to take down a Yonkou before Apoo sold him and Kidd and Killer out.
