Background / History

Natsu was originally END, the strongest Fire Demon created by Zeref from the body of Zeref's deceased younger brother. After END fought the Fire Dragon King Igneel, his demonic power was accidentally sealed and he lost his memories, becoming the ordinary child later known as Natsu 469 474.

Four hundred years ago, Natsu was one of five children selected for a plan to defeat Acnologia. Igneel taught him Fire Dragon Slayer Magic, then hid within Natsu through the Dragon Soul Technique to suppress his Dragon Seed and prevent Dragonization. Natsu was sent into the future through the Eclipse Gate, eventually landing near Fairy Tail and joining the guild 381 469.

For years, Natsu searched for Igneel without realizing that his adoptive father remained within his body. George later used his psychic mental world to reunite Natsu with Igneel, allowing him to learn the truth of his origins, END's identity, and the plan against Acnologia 468 469.

Appearance

Natsu is a young man with short cherry-red hair and a notably powerful, dragon-like physique. Even before his Dragon Slayer Magic is identified, his speed and physical force distinguish him from ordinary fire mages 67 205.

• Short, cherry-red hair 205
• Exceptional physical strength and speed 67
• Often manifests Dragon Slayer flames around his hands or from his mouth in combat 108 152

Personality

Natsu is hot-blooded, impulsive, and fiercely competitive. He reacts violently to insults against Fairy Tail, readily challenges stronger opponents, and frequently clashes with Gray. His determination can make him reckless, such as when he accepts an S-Class mission without authorization or attempts to challenge Laxus 113 142.

He is also deeply attached to his guildmates and his adoptive family. He refuses to abandon Erza during Jellal's attack and is visibly affected by learning that Igneel has been inside him all along 209 468 469.

Abilities & Skills

Fire Dragon Slayer Magic

Natsu uses Fire Dragon Slayer Magic, a Lost Magic taught to him by Igneel. Unlike ordinary fire magic, it is dragon-derived magic and is particularly effective against dragons 71 294.

• Can devour flames to restore or increase his magic power 71
• Dragon Slayer flames can overwhelm ordinary fire magic and resist fire-based defenses more effectively than conventional flames 71 112
• Reinforces his body for high-speed, close-range combat 111
• Grants unusually high endurance against magical attacks due to his dragon-like constitution 284

Fire Dragon's Roar

Natsu exhales a concentrated torrent of Dragon Slayer flames.

• Used to destroy Phantom Lord's ghost soldiers after consuming Fiendfyre 152
• Can be enhanced by consuming stronger flames 152 153

Fire Dragon's Brilliant Flame

Natsu's signature high-output attack combines the flames in both of his hands into a giant blast.

• Destroyed the heavily damaged Three-Eyed Demon alongside Erza and Gray's attacks 109
• After consuming Fiendfyre, produced a thirty-meter red-and-blue fireball capable of assaulting Phantom Lord's mobile castle 153

Fiendfyre Assimilation

Natsu can consume George's Fiendfyre and incorporate its cursed blue-flame properties into his own Dragon Slayer Magic 152 153.

• Temporarily boosts his magic power substantially 152
• Lets his attacks carry Fiendfyre's properties while remaining under his control 152
• Excessive absorption overwhelms his body and causes him to lose control 153

Latent Demonic Nature

Natsu's sealed identity as END gives him exceptional latent potential. Zeref considers him the strongest demon he ever created and believes Natsu may eventually become powerful enough to kill him 469 474.

• END's power was sealed after his battle with Igneel 469
• His true nature was concealed beneath the identity and memories of the human child Natsu 469
• Zeref seeks to force Natsu's growth through hatred and despair 474 476

Weaknesses

• Suffers severe motion sickness on every type of vehicle; levitating him removes the problem 103
• Can be psychologically affected when fighting Erza, whose past victories over him have left him hesitant in sparring matches 284
• Borrowed magical power, including Fiendfyre, can overload his body 153

Relationships

• Happy — His closest companion and fellow magical cat. Natsu found and raised Happy, and Happy frequently accompanies him on missions 68 103.
• Igneel — Natsu's adoptive father and Dragon Slayer Magic teacher. Igneel concealed himself within Natsu to suppress his Dragon Seed and prevent Dragonization 71 469.
• Zeref — Natsu's creator and elder brother. Zeref created END from his younger brother's corpse and wants Natsu to become strong enough to kill him 469 474.
• Erza Scarlet — Guildmate and formidable rival. Erza repeatedly defeats Natsu, though she acknowledges his continued growth 111 284.
• Gray Fullbuster — Competitive guildmate and frequent sparring rival; the two repeatedly argue but fight together when Fairy Tail is threatened 105 109 209.
• Lucy Heartfilia — Teammate who accompanies Natsu on missions and joins him during his reunion with Igneel 113 469.
• George — Guildmate who used Natsu's hair as the core of a powerful wand, supplied him with Fiendfyre during the Phantom Lord conflict, and enabled his reunion with Igneel 98 152 469.
• Makarov Dreyar — Fairy Tail's Guild Master, who regularly restrains or scolds Natsu for his impulsive decisions 113 280.
