Killer should have a huge bounty because we have to take into account his status.
Okay, he just beat Hawkins but he's among Supernovae who took part in the defeat of 2 Emperors.
Zoro -> Supernovae who took part in the defeat of Kaidou and Big Mom + YC of an Emperor -> 1.111 billions
Jinbei -> ex Shichibukai + YC of an Emperor -> 1.100 billions
Sanji -> Vinsmoke's clout + YC of an Emperor -> 1.032 billions
Killer is not an YC commander but he was among the Supernovae who attacked Kaidou and Big Mom.
The WG probably doesn't know he defeated Hawkins and thinks he helped Luffy, Law, Kid and Zoro defeat Kaidou and Big Mom.
So Killer -> Supernovae who took part in the defeat of Kaidou and Big Mom + RHM of a Supernovae who has a 3 billion bounty -> equal to a bounty more or less than Sanji.
