Kong

Kong is the World Government Commander-in-Chief. He was the former Fleet Admiral of the Marines 25 years ago, at the time of the battle of the Edd War, between Gol D. Roger and Shiki.

Appearance
Kong is a muscular, old man with his whitened hair and beard arranged in an array of spikes, similar to a lizard's spine. He also has a stitched scar under his left eye. He wears a sleeveless black shirt adorned with medals, revealing his muscular arms, with armbands, a scarf around his neck, and a Marine coat draped over his shoulders.

Abilities and Powers
While he was the Fleet Admiral of the Marines, he had absolute control of the organization, under the World Government. Now, as World Government Commander in Chief, he works for the World Government, and possesses not only more power over the Marines, but also authority over the Government's espionage agents, the Shichibukai, Enies Lobby, and the Cipher Pols. According to the World Government hierarchy, his authority is second only to the Gorousei.

Haki
It was stated that all Vice Admirals possesses Haki, so with a rank above Vice Admiral, Kong can also use the ability. However, he hasn't been shown using it yet.

Battle of Edd War
Fleet Admiral Kong was seen receiving a report about Shiki fighting Roger, and when Vice Admiral Monkey D. Garp went ahead to the battle, Kong was seen shouting that their conversation was not yet over, despite Garp claiming it was. Kong eventually was promoted from Fleet Admiral to World Government Commander-in-Chief, thus leaving the Marines in Sengoku's hands and working for the World Government.

Post-War Arc
After the Battle of Marineford, Garp approached Kong and resigned from the Marines, despite the latter's attempting to hold him back from it. Three weeks later, Sengoku did the same thing. Kong was somewhat disappointed at these resignations, as both of them were top of the Marines since Roger's time, but allowed them to leave on the conditions that their records and titles not be touched, in order to retain influence to recruit new Marines in the future.

Translation and Dub Issues
Kong's title is 世界政府全軍総帥 Sekai Seifu Zengun Sōsui. 総帥 Sōsui refers to a supreme leader who is in charge of all aspects of the military. 総帥 can be translated as leader, commander, or commander-in-chief.

Some scanlation groups on the internet translated Kong's rank as Pan Fleet Admiral, but this name is wrong, the correct name is World Government Commander-in-Chief.
