The Legend of the Hungry Wolf series chronicles the rise of the "Lone Wolf" Terry Bogard, 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 crimelord 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 Legend of the Hungry Wolf. In the first installment of this "new" series, the final and decisive battle between Terry and Geese takes place from within a new King of Fighters tournament, which would end up leading to the canonical death of Geese Howard in the Legend of the Hungry Wolf storyline. The second installment, which is named Real Bout Legend of the Hungry Wolf Special, features the return of Krauser and a few other fighters from the past Legend of the Hungry Wolf games, although it's to be taken into account that both Real Bout Legend of the Hungry Wolf Special and its following sequel, MediaWiki:Badtitletext are considered to being "dream match" games which has no affect on the current Legend of the Hungry Wolf storyline.
Finally, Garou: Mark of the Wolves takes place a generation later. It focuses on Rock Howard: Terry's protégé and the son of Geese, who makes a shocking discovery about his own past when he enters the King of Fighters: Maximum Mayhem tournament that's being held by a ruthless crimelord named Kain R. Heinlein, who holds an unexpected connection with Rock.
