Iori Yagami is a popular character from the King of Fighters (KOF) series, created by SNK. He first appeared in The King of Fighters '95 as a rival to Kyo Kusanagi, the main protagonist of the series, and has since become one of the most iconic figures in fighting games.

Here are some of the key points about Iori Yagami:

1. Background: Iori belongs to the Yagami clan, which has a long-standing rivalry with the Kusanagi clan due to a centuries-old blood feud. This conflict was sparked by a demonic pact made by the Yagami clan, which granted them power but cursed them with a "bloodline curse," causing each generation to die young and suffer from violent impulses.
2. Personality: Known for his cool, aloof demeanor and intense rage, Iori is an anti-hero in the KOF series. His brooding nature and fierce rivalry with Kyo Kusanagi define much of his character.
3. Fighting Style: Iori's fighting style combines traditional martial arts with a "purple flame" ability derived from his demonic curse. He uses a mix of quick, powerful strikes and claw-like attacks, often incorporating his signature purple flames, which set him apart from most fighters in the series.
4. Design: Iori’s design is iconic, with his distinctive red hair, black leather jacket, and his unique stance where he often hunches over. His moves and animations reflect a feral, almost animalistic style, enhancing his fearsome image.
5. Popularity: Iori’s complex story, distinctive moveset, and intense rivalry with Kyo have made him a fan-favorite. He’s often regarded as one of the best characters in the KOF series and one of the most recognizable characters in fighting games overall.
