Fire Dragon's Iron Fist (火竜の鉄拳 Karyū no Tekken) is a Fire Dragon Slayer Magic Spell.


The user engulfs their fist in flames and then punches their opponent, causing, aside from sheer blunt damage, damage from the flames as well.[1] This attack can also be performed with both hands at once.[2] When the user is Dragonized, this spell becomes far more powerful and gains blue flames.[3] With the power of six other Dragon Slayers, this spell manifests into a giant fist made of flames.[4]


  • Natsu Dragneel momentarily renamed this ability Cat Fire (猫ファイアー Neko Faiā) while wearing a cat mask taken from Millianna's collection.[2]
  • Hiro Mashima said that this technique is Natsu's signature move.
