[@Genon] ~ The bounty is too high. As long as Adrian isn't the one who personally kills a Noble of the Heavenly Dragon, and isn't the leader of the [s]Hashashin[/s] Nightblades group.

Judging from the feats alone he would be about 50 million, or 88 million at most. Still you can put him as 500 million if you want, but what I can say is that a bounty like this is going to shorten the crew's lifespan, even before heading to the Grand Line.
