Kong

Pan-Fleet Admiral Kong 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 wore a black shirt with medals adorned on them and short sleeves, revealing his muscular arms, with armbands, a scarf around his neck, and a Marines jacket over it.

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 Pan-Fleet Admiral.

Post-War Arc
After the Battle of Marineford, Garp approached Kong and resigned from the Marines, despite Kong 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 will not be touched, in order to retain influence to recruit new Marines in the future.
