Magic and Abilities
Iron Dragon Slayer Magic (鉄の滅竜魔法 Tetsu no Metsuryū Mahō): Like Natsu, Gajeel was taught by a dragon to manipulate a particular element into his fighting style: in Gajeel's case, the dragon Metalicana taught him how to use Iron Dragon Slayer Magic. However, as the name implies, his Dragon Slayer Magic deals with iron instead of fire. Just as Natsu eats fire to regain his strength, so can Gajeel eat iron to regain his own. His teeth and jaw muscles are apparently powerful enough to gnaw through solid metal with ease, and he can devour even the Magic-canceling metal of the Dorma Anim. Gajeel's Magic deals with producing multi-sized iron rods as well as changing parts of his body into steel. Most of his attacks involve transforming his arm's into hard-as-steel weapons, which he can do at will.
- Iron Dragon's Sword (鉄竜剣 Tetsuryūken): Gajeel transforms his arm or leg into a large, jagged steel blade, similarly to Iron Dragon's Club, but, rather than blunt power, this spell has cutting power, thereby making it deadlier. The spikes along the blade's edge make its slashes more painful and dangerous, and the weapon's length can be increased to reach enemies who are far away from Gajeel. The blade is also sturdy enough to function as a shield of sorts. In the anime, the sword also functions as a chainsaw, effectively increasing its damage.
Enhanced Smell: Gajeel has an incredible sense of smell, which he shares with other Dragon Slayers. He uses this for tracking purposes as apparently, nothing can escape his nose. This is best shown when he could track Lucy to Fairy Tail's secret hideout. It is also inferred that he used this skill when he was tracking down Levy, who ran away from him in the S-Class Trials out of frustration.
Enhanced Durability: Even without his Dragon Slayer's abilities, Gajeel has consistently proven himself to be one of the more resilient characters in the series: when he was confronted by team Shadow Gear after joining Fairy Tail, he was able to shrug off the combined attacks from Jet and Droy without retaliation and, in the the anime, only resorted to finally summoning his metal scales to increase his defense when Laxus tried to attack Levy. Also later during his battle with Laxus he took an attack which would have killed Natsu, yet he remained conscious. During his time in Edolas, Gajeel used his metal scales to fight Faust's mechanical Dragon, where he absorbed extremely powerful blows with little trouble.
Enhanced Speed: Gajeel's overall speed and reflexes are impressive, enough for him to intercept attacks like Laxus' Magical bolts and reach Levy in time to save her from a double-team ambush of two Grimoire Heart Mages.
Enhanced Strength: Gajeel has shown on different occasions to be incredibly strong: during his time under Jose Porla, while he was tormenting the captured Lucy Heartfilia, Gajeel could casually headbutt a fellow Phantom Lord member who was asking him to stop with enough force to shatter the stone floor he had the man crash on. His physical might is enough for him to clash with Natsu on even terms, to block and shatter Pantherlily's gargantuan Bustermarm Sword, and to pin down and hold still the gigantic Dorma Anime all by himself, allowing Natsu to finish it off.
Master Hand to Hand Combatant: In battle, aside from his Iron Dragon Slayer Magic, Gajeel is known for extensively employing unarmed combat, and to possess great proficiency in doing so: his style is a brutal one, consisting of powerful, direct moves such as devastating punches and headbutts, complemented by his high physical prowess, with his strength making his blows highly damaging, and his speed allowing him to land them in extremely fast succession. When employed alongside his Iron Dragon's Scales, his unarmed blows become far deadlier.
