The Fires Beneath is the ninth episode of Ultraman: The Ultimate Hero. It is known in Japan as Revenge of the Scorching Heat (灼熱の復讐 Shakunetsu no Fukushū), and is instead placed as the seventh episode.
Several mysterious brushfires have been spontaneously igniting near where a logging crew has been working. Frustrated by the lack of work being carried out, and unable to go to the regular authorities, the head of the logging company calls in WINR to investigate the cause of the fires. When WINR discovers that the fires are being caused by the Zambolar who's body temperature is so high that it causes fires to just ignite all around it, they take measures to stop it. However, the heat from the monster's body plays havoc with WINR's equipment forcing Kai to once again transform into Ultraman Powered. Instead of fighting the monster, Powered used his Willpower to cause the flames to die down, as a way of convincing the monster to stop his rampage and go home. Zambolar shockingly complies, as his flames die down in heat and he returns home.
