Well, forgor that. But it still doesn't justify that bounty.
As Gorosei aint top tiers, they are just inmortal and each of them have one great stat.
Luffy didnt have trouble handing them, included Kizaru lol. They just couldn't die.
Destroying Kidd's ship great feat... but its a ship lol.
1.8 billion is a lot.
I really dont think they should be above Kings bounty.
