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. This attack can also be performed with both hands at once.
- 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.
- Hiro Mashima said that this technique is Natsu's signature move.
