Samba Island is a non-canon island in the New World, previously protected by the Whitebeard Pirates and later ruled by Chameleone as a tyrant.
Not much is known about the island's geography since it has yet to make an appearance.
The only named citizen of the island is Chameleon who used to be the tyrant of the island after Whitebeard's death.
Samba Island was under the Whitebeard Pirates' protection until Edward Newgate's death in the Battle of Marineford.
After the Whitebeard Pirates' flag lost its protection value, Chameleone took control of it and became a tyrant until Monkey D. Luffy and Straw Hat Pirates defeated him.
