Duck King is a character from the Fatal Fury and The King of Fighters series.

Duck King developed his unique fighting style when he met and lost to Terry in a street fight. During the Fatal Fury series, he often strives to improve his dancing skills and prove himself against his rival. He frequently likes to visit and party at Richard Meyer’s night club, the Pao Pao Café.

In The King of Fighters XI, he is part of Team Fatal Fury composed of Terry and Kim Kaphwan. He is invited by Terry; but it took him, Choi and Chang to convince Kim to join the team.

A friendly and outgoing guy towards everyone, Duck King lives to dance and party. He shows little respect concerning those he deems to be evil like Geese Howard. He considers Terry to be his martial arts rival, but otherwise regards him to be a good friend.
