God Slayer Magic

God Slayer magic is similar to Dragon Slayer magic, but is apparently more powerful. The only known user of God-Slayer magic is Zancrow. However, Zancrow learnt this magic from Hades, not from an actual god. It is unknown if 'genuine' God-Slayers exist, or if 'genuine' God-Slayer magic even exists. Nonetheless, Zancrow's flame magic has been shown to be completely superior to Natsu's Dragon-Slayer magic in both power and destructive ability. However, Natsu was only able to eat Zancrow's flames after nullifying all of his own magic, while Zancrow could eat Natsu's flames with ease.

FlameEdit
A God-Slayer style which incorporates the element of fire into the user's body. This allows the user to produce black flames from any part of their body. The user is also able to consume flames of any sort to replenish his/her strength. Zancrow says that his flames, in addition to being able to burn, are "flare halberds that destroy everything," which implies that his flames have a high amount of destructive ability.
 * Known User(s): Zancrow

Spells:
 * Flame God's Kagutsuchi (炎神のカグツチ Enjin no Kagutsuchi): Zancrow spreads his arms and legs and unleashes a giant ball of black flame around his person. This was first seen against Natsu, and completely overpowered Natsu's "Brilliant Flame".
 * Flame God's Bellow (炎神の怒号 Enjin no Dogō): A similar attack to Natsu's "Fire Dragon Roar", Zancrow breathes a massive fireball of flame at his opponent. While using this attack his fire is normal-colored, not black, although this is presumably due to the fact that Zancrow had just consumed Natsu's flames a moment earlier.
 * Flame God's Supper (炎神の晩餐 Enjin no Bansan): An attack where Zancrow claps his hands down to launch mouth-shaped attack of black flames at his foe(s) to trap them in the black flames to turn them into ashes.
 * Flame God's Punch Attack: An unnamed attack where Zancrow releases a massive stream of black flame at his opponent by launching his arm forward in a punch-like motion. This attack demonstrated that Natsu couldn't eat Zancrow's flames. (Unnamed)
 * Flame God's Scythe Attack: An unnamed attack where Zancrow forms a scythe of black flames off of one arm, which he uses as a weapon for destructive results. This attack was first demonstrated when Zancrow used it to cut down a couple of trees. (Unnamed)
