Hidden Fire Form: Crimson Lotus: Phoenix Blade (不知火型 紅蓮鳳凰剣 Shiranuigata Guren Hōōken) is a Fire Dragon Slayer Magic Spell.
While in Dragon Force, the user surrounds their entire body with fire and then propels themselves toward the target, leaving behind a long wake of flames, and hitting them with a devastating headbutt. This unstoppable and destructive spell was used to defeat Zero and destroy one of Nirvana's leg-powering Lacrima, as well as deal high damage to Mard Geer Tartaros in his Etherious Form.
