Natsu Dragneel (ナツ・ドラグニル Natsu Doraguniru?), also known by the nickname "Salamander" (火竜(サラマンダー) Saramandā?), is the main male protagonist of Fairy Tail. Aside from performing missions for his guild, Natsu travels with his partner Happy in search of Igneel, a dragon who raised Natsu in his youth before disappearing seven years prior to the start of the series.[6] He is a Dragon Slayer (滅竜魔導士(ドラゴンスレイヤー) Doragon Sureiyā?), a wizard who can perform an ancient form of magic, or "Lost Magic", that grants him the physical properties of a dragon. He specializes in a particular form of this magic called Fire Dragon Slayer magic (火の滅竜魔法 Ka no Metsuryū mahō?), which gives him powers such as breathing fire, emitting flames from any part of his body to attack his opponent, being physically immune to fire, and ingesting any flame besides his own for nourishment.[3][7] When he consumes magical substances containing numerous elemental properties besides fire, such as lacrima infused with Etherion, Natsu is able to achieve a more powerful form of Dragon Slayer magic called "Dragon Force" (ドラゴンフォース Doragon Fōsu?), which turns his skin around his eyes and on his forearms scaly, and increases both his physical and magical power.[8] Eating any other form of magic temporarily grants Natsu the ability to combine the properties of that magic with his own (such as eating Laxus's lightning magic, which electrifies his body). However, eating any magic besides fire causes Natsu to become sick for several days after the effects of his transformation wear off. Natsu is generally carefree and reckless in nature, and causes most of the collateral damage Fairy Tail is blamed for.[9] However, he is extremely loyal to his guildmates and attacks anyone who tries to harm or insult them. Although he comes across as thick-headed to several other characters, he is a perceptive tactician in battle and can quickly deduce his opponents' strengths and weaknesses.[10] He suffers from motion sickness when riding on vehicles of any sort (trains, carriages, boats, etc.), as well as when carried by others. The only exception to this rule is Happy, who Natsu claims is his friend and not a "moving object".[11] He is prone to challenging his guild's S-Class wizards to petty fights to test his strength, in which he is often defeated with little effort from his opponents. When properly motivated to fight (e.g. saving the lives of his friends) he is recognized as one of the most powerful wizards in the guild.[12] He is voiced by Tetsuya Kakihara in Japanese and Todd Haberkorn in English.
