The hate on Killer
, the WG for me will give all 5 a minimum 1B increase for playing a hand in defeating the 2 yonko

Likewise, Killer's most notable accomplishment is beating Hawkins. If anything, I see Killer potentially getting over a billion just because he is Kidd's right hand man.
Just "fighting an emperor" isn't enough to get someone a 5 digit bounty.
