The berserk fight of Natsu

Natsu's nickname is "Salamander", and he is often recognized by his pink hair, scale-skin scarf, and fire magic. He was raised by the dragon, Igneel, who taught him how to talk, write, and use an ancient style of magic known as "Dragon Slayer". Because of his magic, Natsu can eat any flame other than his own for nourishment. He can also emit fire from any part of his body. The size and power of the flame is a direct result of Natsu's mood, so when properly motivated in a battle he is recognized as one of the strongest wizards in Fairy Tail. During the series, Natsu consumes some Lacrima containing Etherion, the magic beam that was fired by the Magic Council and captured in solid form in the crystal, which greatly improves his abilities; his skin becomes scaly, and his speed and the strength of his fire are also greatly increased.
