Tetsutetsu Tetsutetsu

Rows of pointed teeth and a permanent scowl give Tetsutetsu a face that matches how he fights. Messy gray hair falls to his chin and somehow never changes shape, eyebrows are absent entirely, and his black eyes angle sharply inward beneath heavy tan lashes that read as jagged spikes. The teeth, like much else, echo Eijiro Kirishima.

He works in a pale green jumpsuit cropped below the chest, its baggy legs punched with small silver-ringed holes, over boots plated in metal at the sole, heel and toe. Steel banding crosses his shoulders and runs beneath his arms toward a red oval at his sternum, with thinner rings on each bicep and plates at either hip that tie into a brown sash of pouches and a large gray container. A jaw guard shields his face, stamped on both sides with Fe, the periodic symbol for iron.

The timeskip leaves him taller and thicker through the body, hair cropped and swept back in spikes, lashes longer still. His costume survives largely intact, lightly reworked, with the jaw guard pulled back to shield just his ears and cheeks.

Hotheaded barely covers it. Tetsutetsu announces exactly what he intends to do and then does it, favoring the shortest route through any problem, a habit that surfaces in a fighting style built on forward pressure instead of trickery.

His first meeting with Class 1-A was a shouted challenge; he read them as looking down on 1-B and wanted the record corrected. Katsuki Bakugo's arrogance in particular made him a target, and Tetsutetsu entered the U.A. Sports Festival intent on winning the thing outright. He still ended up friends with Eijiro and cheered him on there, without ever letting go of the need to prove his class belonged.

When 1-B was written off as second-rate once the first term closed, their own homeroom teacher included in the verdict, he was reduced to tears while apologizing for the disappointment. The villain attack that followed he treated as an opportunity to be tested the way 1-A had been at the Unforeseen Simulation Joint. For all the noise, his classmates come first: he made sure Ibara Shiozaki was clear before engaging, and he took a bullet aimed at Itsuka Kendo without hesitating.

Real Steel is a durable, punishing combatant. Eighth place in U.A.'s entrance exam, fourth on villain points alone, says enough about raw force and refusal to stop. His Quirk lets him soak damage and answer it in kind, and a fully steeled body ignores gunfire at close range, so he readily plants himself between danger and whoever is behind him.

Against Eijiro, a brawler cut from the same cloth, neither could win: their Sports Festival bout ended level and the arm-wrestling tiebreaker fizzled once Tetsutetsu's iron ran low and his stamina went with it. At the Quirk Training Camp he and Battle Fist took down the League's Mustard together, Tetsutetsu weathering the boy's Gas and his own Quirk fatigue long enough for Kendo to open a gap for one finishing punch. Later, in the Joint Training Battle, a coordinated ambush alongside Pony Tsunotori pinned Shoto Todoroki into close quarters, and Tetsutetsu pushed through heat capable of melting steel until the collapsing terrain ended things in a draw.

He is also more calculating than he sounds. Mustard's uniform told him roughly how old the villain was; against Shoto he correctly judged that Steel favored him in a long grind, and he caught the moment his opponent warmed himself deliberately to break the hold. The will is the constant. He ignored orders to stay clear of the fighting at the Vanguard Action Squad Invasion, arguing that future heroes owe people protection, and he holds that limits exist to be broken, that a trainee unwilling to risk himself in training never will in the field. In the anime he found the strength to seize one of All For One's tendrils and hurl it clear, helping open a path for Izuku Midoriya.

Steel: his whole body converts to solid metal, multiplying durability and power together. In that state he has shrugged off falling wreckage, encasement in ice, the remains of Villain Bot Executor, and flames from both Shoto and Dabi, and he can crash through hardened structures without injury. The same form lets him shatter concrete, rip industrial piping apart, and trade blows evenly with Eijiro; during their arm wrestling his fingers sank into the concrete beneath them. The cost is iron, drawn straight out of his body, so an iron-rich diet is not optional, and extended use brings on iron fatigue that dulls both toughness and output. Extreme temperatures can melt him, magnetism is a liability, and unlike Hardening, which grows under stress, Steel has a ceiling he admits cannot be raised.

His ultimate moves lean on the same logic. Steel Fist is a full-metal charge into one reinforced punch, enough to break ice apart and launch a target across the field. Horn Dash Hammer pairs him with Pony, whose Horn Cannon launches him at an enemy as a guided slab of momentum. Heatetsu turns absorbed heat into a weapon, his steel glowing red as he presses the attack, as it did against Shoto.
