Chang Koehan is a playable character in The King of Fighters series.

Profile
He was once a feared and violent criminal in Korea. He was spotted by Kim Kaphwan from a prison's surveillance footage and he wanted to use Chang's strength "for justice". Though Chang easily broke out of prison, he was caught by Kim and forced to undergo Kim's "Rehabilitation Project" in KOF. During this time, he befriends a fellow convict who was also caught by Kim, Choi Bounge. Together, they initially schemed for ways of escape but they eventually mellow out and enjoy their companions' company — with protests saying otherwise.
