Sorbet Kingdom

The Sorube Kingdom is a nation somewhere in the world that was once ruled by the former revolutionary turned Shichibukai, King Bartholomew Kuma before he was turned into a cyborg puppet and made the slave of the World Nobles to serve as an example to any who would dare defy the rule of the World Government.

Geography
Nothing is known about the country's geography because it has yet to make an appearance.

Past
At an unknown point in the past, the kingdom's ruler, Bartholomew Kuma joined the Revolutionary Army, but due to unknown events ended up leaving the Revolutionaries and losing his royal status to become a member of the Shichibukai where he began slowly being converted into a cyborg by Dr. Vegapunk.

Marineford Arc
Right before the Battle of Marineford took place, Vegapunk completed Kuma's cyborg modifications, taking away the former king's free will and personality in the process, turning him into the mindless slave of the World Government. However, with help from Vegapunk, the former king would fulfill his last mission by protecting the Straw Hat Pirates' ship from harm for the next 2 years.

Reverie Arc
After Kuma completed his last request, he returned to Mary Geoise where he submitted himself to cruel and torturous slavery at the hands the World Nobles to serve as an example to any kingdom that would dare defy the World Nobles, and to show that even royalty can be enslaved.

Trivia
