The Sentinels are a militaristic organization that are similar to a private army. They exist outside of the World Government and survive without having received any assistance from them. Their group defends Blank Island and its denizens from rowdy pirates that may cause any problems.



It is unknown how long the Sentinels have existed or when they formed their group.

At some point in time the World Government tried to strong arm their way into the territory of Blank Island in order to assimilate them into the allied countries of the world, but Gustav resisted their efforts and did not permit them to take over his home.

Blank IslandEdit

When the Straw Hat Pirates arrived at Blank Island the Buggy Pirates were stirring up trouble only to garner attention from Senior General Amol who fought against the crew and managed to cause Buggy to fear for his life, forcing them to flee.

Junior General Nae then encountered the Straw Hats on the beach, assuming that they had caused all the damage around there and instigated a fight with them, which resulted in him being defeated by Kedamono Jeran. Amol showed up shortly after only to reprimand his own subordinate for causing trouble for the pirates who had helped them clear out a group of rowdy pirates. Before he could lead them to any kind of lodging as payment, an explosion hit the beach and Buggy and his crew showed up to fight the Straw Hats.

After the battle was over both Amol and Nae were taken onto the Sunny for medical attention while a man on horseback wearing the same Sentinels uniform was seen observing the fight before leaving to report back to the "chief."
