Longarm Tribe

Longarm Tribe are a tribe of humans in the series. Scratchmen Apoo, captain of the On Air Pirates and one of the Eleven Supernovas, is the only named member of this tribe.

Appearance
As their names suggest, all members of the Longarm Tribe seen so far have four elbows, which result in their really long arms. Furthermore, all members seen so far wear Chinese style clothing, with a kanji in the front; the kanji depends on the members' choice. Other than that, they have the appearance of normal humans.

Inter-species Relationships
The Longarm Tribe are valued as slaves by normal humans considering the standard price for a Longarm Tribe member is 700,000.

Apparently they are the ones responsible for destroying the country of Harahetternia of Namakura Island. The cultists of Namakura Island were in the middle of trying to summon Satan, wanting him to help destroy the Longarm Tribe. However, due to Kuma, Brook landed right in the middle of the summoning. Believing him to be Satan, the people of Namakura Island want him to help them get revenge on the Longarm Tribe. Several members of the Longarm tribe then proceeded to kidnap Brook to put him on display as the world's only moving skeleton. Two years later, the three longarms who kidnapped Brook all became his managers when he became a famous rockstar known as "Soul King". However, upon learning that Brook is a pirate, and that he plans to retire after one final concert in order to rejoin the Straw Hats, the three called the Marines on him, but they were stopped by the fans from arresting Brook so that he can perform his last song.

Trivia

 * The Japanese name of the tribe, Tenaga, and the tribe people appear to be based on Japanese mythological monster called a Tenaga whose most notable characteristics were long arms.
