"He... Could he be the only prince of Praia, the Prosecutor General of the World Government, the heir to the Harunkefilia family, one of the five major families of the Celestial Dragons, Greene who was a disciple of Akainu and is known as the most powerful person in the world?!!"

Any similarity is purely coincidental and should not be imitated.
