Fatal Fury: King of Fighters, known as Garō Densetsu: Shukumei no Tatakai (餓狼伝説 ～宿命の闘い～, Hungry Wolf Legend: The Battle of Destiny) in Japan, is a 1991 head-to-head fighting game originally released by SNK for the Neo Geo arcade and home platforms.

Knowing that they weren't strong enough and needed more training to confront Geese, the brothers made an oath to spend a decade to fine tune their martial arts before trying to avenge their adoptive father.

After the Bogard brothers pay respects to Jeff's grave, they encounter and befriend a Japanese Muay Thai champion named Joe Higashi from Thailand and learn about the KOF tournament hosted by Geese.

Determined to avenge their adoptive father's death, Terry and Andy enter KOF alongside Joe and fought against many competitors, including Tung Fu Rue who had wanted to test the brothers out in making sure they were ready for their potential battle against Geese.

As Terry, who had finally avenged his adoptive father's death left the tournament victorious, Andy felt a mixed sense of closure and returned to Japan to continue his martial arts training while Joe, who had said his goodbye to the brothers after the tournament's conclusion, traveled back to Thailand in order to continue his Muay Thai training.

The player is then given the next option to select from one of four fighters as their first opponent: Duck King, Richard Meyer, Michael Max, and Tung Fu Rue.

After leaving Capcom for SNK, Nishiyama wanted to create a fighting game with a storyline and characters that were easier to empathize with, something he wasn’t able to achieve with Street Fighter.

[11] Veteran developer Yasuyuki Oda believes the detailed facial expressions and 2D backgrounds were the secret behind Fatal Fury's fame.

[12] Nishiyama originally created Terry for Street Fighter as a Caucasian man wearing a leather jacket; they decided to make the main playable character a dougi-clad karateka name Ryu instead.

[14] In the making of the series, Terry and his brother Andy were characterized as the heroic leads, contrasting with the comical Joe Higashi.

[12] In Japan, Game Machine listed Fatal Fury: King of Fighters on their January 1, 1992 issue as being the third most-successful table arcade unit of the month.

[28] It went on to be Japan's fourth highest-grossing arcade game of 1992, below Street Fighter II (two versions) and Captain Commando.

"[22] In a retrospective review, Maximum commented in 1996 that the game failed to offer any real competition for Street Fighter II in either playability or character selection.

They concluded, "The only main point in this game's favor is that two of the characters may team together to take on a computer opponent in a three-player frenzy, and the game also tries to offer something else new with a two-tier playing arena, but the slow action and the disgracefully difficult fireball motions make special moves something of a rare occurrence.

"[31] The Fatal Fury series inspired a trilogy of animated productions produced by NAS with SNK, featuring character designs by Masami Ōbari.

The first is a television special that aired in 1992 on Fuji TV titled Fatal Fury: Legend of the Hungry Wolf (Battle Fighters Garou Densetsu), which adapts the plot of the first game.

The character's popularity in Fatal Fury and his younger look from the first original video animation influenced his appearance in Art of Fighting 2 as a hidden boss.

[32] Many soundtracks, manga comics, other books, video tapes, and drama CDs have been released in Japan for the series as a whole[33] and for each of its individual entries.
