Dragon Slayer

There is a unique variety in the diverse forms of magic that can be seen all across the land of Fiore, and barring a few minor exceptions, very few mages have the exact same ability.

Overview
According to Fairy Tail Guild Master Makarov, magic is the embodiment of the connection between the Spirit flow within a person, and the Spirit flow within nature. How this connection is embodied, however, is almost entirely unique to the user. There are only a few exceptions to this, an example of which is Elfman's family, who all exhibit skill in using "Take-Over" magic.

Dragon Slayer
A specialised form of magic which the series suggests can only be learned from the dragons themselves. Dragon Slayer allows the user, to a certain degree, to merge with a specific element. This means that their body's composition transforms to suit the new element. As a result of this, those with Dragon Slayer abilities are able to change their body to their own element, in both offensive and defensive styles. They can also consume external sources of their natural element to replenish themselves, although it has been demonstrated that certain foreign substances will substantially increase their power, ie. Natsu's consumption of Aetherion greatly increases both the strength of his body, and his magic.

Fire
Dragon: Igneel Known User(s): Natsu Dragonil A Dragon Slayer ability which incorporates the element of fire into the user's body. This allows the user to produce flames from any part of their body, including their lungs, giving them the ability to, in essence, breathe fire. It also allows the user to consume external sources of fire to restore their body to a healthy state, meaning that they cannot use their own flames to renew themselves. As well as the added benefits of their elemental advantage, the Dragon Slayer magic gives the user a much greater level of endurance. This in turn is greatly enhanced by the consumption of Aetherion, which not only boosts physical strength and magic, but also causes a layer of hardened scales to appear on the user's body. However, due to the poisonous properties associated with the crystal, it is considered highly dangerous to take the substance into the body, regardless of the benefits. Technique(s):
 * Salamander's Roar: One of the most common techniques that is used by Natsu, Salamander's Roar involves the gathering of fire in the lungs, and then blowing it out in a large tongue of flame. This technique was first seen in Chapter 1, when Natsu uses it to defeat Bora's crew.
