(The King of Fighters' usual Fatal Fury team)
Story:
The Fatal Fury series chronicles the rise of the "Lone Wolf" Terry Bogard (hence the Japanese title, 餓狼伝説 or Garō Densetsu, which translates to Legend of the Hungry Wolf), and the simultaneous fall of the criminal empire of Geese Howard. Like many other SNK titles of the time, the first installment takes place in a fictitious American city called South Town. Brimming with violence and corruption, South Town forms the ideal backdrop for the annual King of Fighters fighting tournament, organized by the notorious crime lord Geese Howard. No fighter has ever managed to beat his right-hand man and appointed champion, Billy Kane, until Terry arrives on the scene.
The second installment of the series features Geese's half-brother, Wolfgang Krauser, who internationalizes the formerly South Town-only tournament in a bid to take on the world's strongest combatants. The King of Fighters tournament is no longer a part of the storyline by the third game, having been spun off into its own series. Instead, the third installment centers around Terry Bogard's attempts to stop Geese from obtaining an ancient scroll that would give him the powers of a lost and dangerous martial art form.
After the third game, the series is renamed to Real Bout Fatal Fury. In the first installment of this "new" series we see the final and decisive battle between Terry and Geese. Note that King of Fighters tournament also held in this game. The second installment, which is named Real Bout Fatal Fury Special, features the return of Wolfgang.
Finally, Garou: Mark of the Wolves takes place a generation later. It focuses on Rock Howard, Terry's protégé and son of Geese, who makes a shocking discovery about his past when he enters the King of Fighters: Maximum Mayhem tournament.
Liste of Fatal Fury characters
Gameplay:
The main fighting game feature that the original Fatal Fury was known for was the two-plane system. Characters would fight from two different planes, and by stepping between the planes, attacks could be dodged with ease. Later games dropped the two-plane system, replacing it with a complex system of dodging including everything from simple half second dodges into the background to a three plane system. Characters often had moves that could attack across the two planes, attack both planes at once, or otherwise attack characters attempting to dodge.
Later Fatal Fury games experimented with various mechanic changes. "Ring-outs", where a character loses the round if the character is thrown into the edges of the fighting backdrop; single-plane backdrops, where the element of dodging is eliminated altogether causing moves that sent opponents to the opposite plane to do collateral damage. The most successful of these gimmicks were the Deadly Rave and Just Defend. The Deadly Rave was a super combo used by several characters, where after execution, a player had to press a preset series of buttons with exact timing for the entire combo to execute. The Just Defend was a type of protected block in which players regain lost life, did not wear down the player's guard crush meter and removed all block stuns making combo interruptions smoother.
