Spitfire

スピット・ファイア

Spitfire (Supitto Faia) was the Flame King and one of the last two members of the original Sleeping Forest who still held their titles at the start of the story. He first appears in the series when Ikki accidentally stumbles upon a secret meeting involving AT riders. He claims that Ikki, as merely an 'F' class rider, has only a 1% chance of defeating Buccha, and he is surprised by the outcome. In the anime, he is introduced in the first episode after watching the leader of the Skullsaders challenge Ikki to a battle. He controls three teams with 41, 68, and 86 members, respectively, and works as a highly sought-after hair stylist in his daily life. His speed creates the illusion of flames due to the heat generated by the friction of his wheels on the ground. In recent chapters, he engages Sora in an AT battle. During the fight, Sano joins in, saves Spitfire, and the two challenge Nike. It is revealed that Spitfire can also stop time, similar to Sano, claiming that while Nike is the strongest of Genesis, he cannot break the flames of time. The fight drags on, and Spitfire concludes that they cannot win. At his request, Sano gives Spitfire enough time to grab Kazu and flee, forcefully giving Kazu the Flame Regalia. Shortly after returning to the battle, both Sano and Spitfire are killed by Sora and Nike. Before his death, Spitfire had foreseen this outcome and left a video explaining the true intentions of Genesis and how, after watching the fight between Kogarasumaru and Behemoth, he was reminded that what he really wanted to do was fly freely in the sky. Spitfire also predicted that Ikki would "lose his wings" due to Sora's betrayal, and part of the reason for the video was to bring Ikki back to the AT world; at the end of the message, Spitfire shows mild concern that his plan might not work.
Spitfire (and the Flame Road in general) seems to be characterized by a flaming fox with nine tails, a reference to the Kitsune from Japanese Mythology.
In the English dub, he has a Cockney accent.
