Fire Dragon King Mode (モード炎竜王 Mōdo Enryūō) is a Fire Dragon Slayer ability.


Fire Dragon King Mode is a unique ability granted unto a Fire Dragon Slayer by Igneel, the Fire Dragon King. As a result of the sheer volume of the Magic Power itself, before even properly utilizing the power to its fullest, the user radiates incredible heat, and their speed and power drastically increase to levels that allow them to fight toe-to-toe with beings as incredulously powerful as Zeref, and even completely incinerate forbidden, powerful Magic such as Ankhseram Black Magic. When the mode is activated, in a radius expanding meters, the ground itself becomes lit in a circular inferno; bodies of water near the user, like a lake, quickly evaporates away, leaving nothing behind; and the clothes of anyone nearby burn off from the heat.[1][2]

Originally utilizing the residual, inert Magic Power of Igneel that resides within the Dragon Slayer, a draconian tattoo appears on their arm that serves as the physical manifestation of the aforementioned Magic Power; this power took the original user, Natsu Dragneel, who is extremely powerful in his own right, ten months of dedicated training to master. The Magic Power bestowed to the user is said to be the manifestation of Igneel's undying will, however, it is extremely finite, and once it runs out, the user can never utilize its power again.[3] Even with the absence of Igneel's power, the user can still utilize this mode using their own power as a substitute, though it is no longer as powerful as before.[4]
