Hero Resurrected (ヒーロー復活, Hīrō Fukkatsu) is the seventieth episode of the Fire Force anime, the twenty-second episode of the third season and the tenth episode of its second cour.
Arthur has exocised the great despair. Just as everyone wonders if the Great Cataclysm has stopped, the moon begins falling toward Earth. At the same time, Kurono and Joker face off against their doppelgangers. And then the "strongest demon" also appears.
Summary
With Arthur's defeat of Dragon, the flames of the Great Calaclysm begin to die down, sending Faerie into paroxysms of anger. Meanwhile, Kurono fights his psychotic doppelganger who is surprised at the berserker personality that others have attributed to him. Although their powers are evenly matched, the real Kurono is the more skilled fighter, and he defeats his doppelganger. Elsewhere, Joker is facing his own doppelganger with what appears to be the Burns doppelganger. Instead, Burns kills the doppelganger, explaining that in Adolla, he defeated and suppressed his own doppelganger and took control of it. In the sky above, Shinmon faces his doppelganger who thinks he is supremely powerful, but Shinmon easily defeats him because people don't believe he is that powerful, much to his disappointment. In effect, doppelgangers have the attributes people think they should have. In Adolla, Sister Iris meets her doppelganger, Amaterasu. Sho confronts Faerie and stabs him, but Faerie has the last laugh as he commits suicide just as the moon begins to drift towards Earth, causing mass despair. However, Shinra bursts onto the scene, and with a supreme effort, he pushes the moon back up into the sky. Sho joins him, and they head into Adolla where they encounter Haumea.
