Ace formed his pirate crew named "SPADE" pirates after leaving his hometown.
After having a continuous clash between Ace and Whitebeard, Ace understood the feelings of Edward Newgate toward his crew and how he considers them as his own family. He also tells them if he joins, they will accept Ace as his family in his crew. He, along with his former crewmates, abandoned SPADE pirates. Afterward, all SPADE pirates had disbanded in different Whitebeard divisions. After Ace's death, they didn't appear in anime or manga.
