#8 – Vergo


Vergo was one of the four elite officers. At age 26, he enlisted in the Marines under Doflamingo’s orders.

Caesar Clown used to work with Marines as their scientist. During the Dressrosa Arc, Donquixote Doflamingo declared Caesar to be his direct subordinate, meaning Caesar was a de facto member of the Donquixote Pirates.

#5 – Donquixote Rosinante

Donquixote Rosinante was the younger brother of Donquixote Doflamingo. He became an Elite Officer of the Donquixote Pirates, serving under Doflamingo under the codename Corazon.

Shiryu of the Rain was the Head Jailer of Impel Down until he was imprisoned for his excessive violence towards the prisoners. For that, he was sentenced to death and put on death row in Level 6.

Who’s-Who is one of the Tobiroppo, the strongest six Shinuchi of the Beasts Pirates.
Over a decade ago, he served in the World Government’s CP9 agency, before his failure in a mission to guard the Gomu Gomu no Mi led to his dismissal from service and being imprisoned. Upon escaping, Who’s-Who turned to piracy, becoming captain of the Who’s-Who Pirates before eventually joining the Beasts Pirates.

Kuzan, better known by his epithet Aokiji, is a former Marine Admiral and the first one to be revealed. He was nominated by Sengoku for the position of Fleet Admiral. However, after losing the position to Sakazuki, he resigned from the Marines and affiliated himself with the Blackbeard Pirates. It is unknown what standing he has with the crew, but some like Jesus Burgess are not so quick to trust him because of his past as a Marine, but Blackbeard pays it no mind.
