Since the KOF '95 project began with the concept of introducing Iori as Kyo's rival, he became known as a character who was a member of a rival school of martial arts that had a connection to the Ancient Arts of the Kusanagi. He was also given the ability to use a different color of flames other than Kyo's (red flames), along with various other characteristics.

When you think of Iori Yagami, his intense personality most likely comes to mind.

His moves are unique, and his singular choice of hairstyle, wardrobe, and manner of speaking was certainly a personality that broke the mold for characters in fighting games at that time.

During the initial location tests to determine the popularity of the game, Iori was the character who stood out most. His hair and his lines to provoke his opponents ("You think I'm scary, do you?") excited his fans to no end.
