Bluejam

Bluejam is the captain of the Bluejam Pirates. Both Ace and Sabo steal their money to buy a pirate ship. After Porchemy's defeat at the hands of Ace and Sabo, Bluejam shot Porchemy. Later, Sabo's father paid him and his crew to find his son for him so he could return home to live with his family. He was also ordered to "take care" of Ace and Luffy so that could never see Sabo again.
