Fire Dragon Slayer Magic (炎の滅竜魔法 Honō no Metsuryū Mahō): Natsu is adept with his Dragon Slayer Magic and makes use of it in many different ways in combat.As with all Dragon Slayers, he can consume his respective element, with the exception of that which he has created, to replenish his energy reserves. The heat of his fire can increase in temperature, which is proportional to Natsu's emotional state. Natsu subconsciously used this against Erigor; his flame's heat significantly rose as he got more enraged. This is also called the Flame of Emotion. He incorporates the flames he ignites into his fighting style, greatly increasing the damage of his blows.As such, Natsu's Magic revolves around the usage of fire that can spout from any part of his body. Natsu's ability to eat flames gives him immunity to most types of flames and allows him to spew fire from his lungs.This fire is exceptionally strong - equivalent to a Dragon's fire - being able to burn even through metal. He can even use his flames to create a propulsive effect.The type of fire he uses can be changed. For example, it can be solidified to cling to surfaces. By the year X792, after one year of training, Natsu has shown improved mastery over his Dragon Slayer Magic as he is now capable of taking out multiple opponents with just one attack, as shown when he challenged and easily defeated the team of the newly announced No.1 guild in Fiore,Scarmiglione,and later was able to defeat Bluenote Stinger in one hit.
