Spade Pirates

Not much is known about the Spade Pirates (スペード海賊団, Supēdo Kaizokudan) other than the fact that two years before the current storyline, Portgas D. Ace was their captain. After suffering a defeat against the Whitebeard Pirates Ace was asked to join their crew. Due to him accepting the offer the crew either disbanded or join with the Whitebeard Pirates.
