Richard Seabright is the current captain of the Ackler Pirates, and is holding a ridiculously large bounty to go with it. While his crew lost Yonkou status with the loss of its captain, the crew is massivley powerfull, and the stand in captain shows his crews power well.
He doesn't know about the tragedy that is his family with them all dead other then his son, Edward Seabright, but he left his son on good terms, and will help him out in his need. He is also allied with the Revenge pirates, but is fighting against them in for the empty Yonkou postion.
