Kuzan is a very memorable character in One Piece who was introduced to the fans before the 2-year timeskip for the very first time. Making his debut during the Water Seven saga, Kuzan was revealed to be an Admiral of the Navy. It was through him that it was made known to the fans that the Admirals are actually the greatest military force when it comes to the Navy. He played a significant role in the back story of Nico Robin and, later on, also took part in the Paramount War.
