"I'm in Class 1-B of the Hero Course! If I don't stand up here, what's the point?! I'm gonna find these jerks and beat the snot out of them!"

Tetsutetsu Tetsutetsu to Itsuka Kendo in "Smoke Signal"



Tetsutetsu Tetsutetsu (鉄哲徹鐵 Tetsutetsu Tetsutetsu?) is a student in Class 1-B at U.A. High.

Appearance

Tetsutetsu is a young man with gray hair, no eyebrows and thick pale eyelashes that encompass his eyes. Like Eijiro Kirishima, he also has razor sharp teeth.

Personality

Tetsutetsu has a tendency to act hot headed and lets his emotions get the better of him, though he also is not too stubborn to cheer for a rival, as he did so in Eijiro's match with Katsuki. He tends to have a one-track mind, and is very straightforward in his solutions to problems, as shown with his eagerness to charge straight into a fight with Mustard. He has very simple solutions to problems, and will often go about things in the most direct manner. He also tends to be vocal about his intentions.

Tetsutetsu is very determined to improve himself, as he apologized to his teacher for doing bad and vowed to do better. When villains attacked, he took the chance to expose himself to danger and grow from it. When in these fights, he is tenacious and unwilling to back down, relying on brute strength to get through rather than use much strategy.

However, he also cares for his classmates, as he didn't face the villains before making sure that he left Ibara in the care of someone else. He also threw himself in front of Itsuka when Mustard fired on her without hesitation, despite this putting himself at risk due to his own Quirks weakening effects.

Tetsutetsu strikes

Tetsutetsu attacks Mustard.

Tetsutetsu and Itsuka continue walking through the forest; Itsuka realizes that the gas is not dispersing and surmises that a villain is manipulating the gas; they decide to find the villain responsible for the gas. As Tetsutetsu and Itsuka reach the source of the poisonous gas, Mustard feels their presence and is impressed that they figured out the gas phenomena; he takes out a gun in preparation for their arrival. Suddenly, Tetsutetsu appears in front of Mustard and prepares to attack him with his steel fist. However, Mustard fires his gun at Tetsutetsu.[25]

Tetsutetsu manages to block Mustard's bullet using his Quirk. Mustard shoots at Itsuka but Tetsutetsu throws himself in front of Itsuka to block the bullet. After Mustard attacks Tetsutetsu repeatedly, Itsuka attacks but Mustard evades; Itsuka enlarges her right hand and smacks Mustard away. Seeing that the gas is a hindrance, Itsuka enlarges her hands, uses them to swirl the gas away, and mocks Mustard for acting cowardly by using a gun to fight. Mustard prepares to fire his gun at Itsuka for her insult. Out of nowhere, Tetsutetsu appears behind Mustard, who was unable to notice Tetsutetsu's presence due to the gas dispersing courtesy of Itsuka. Tetsutetsu holds his breath and punches Mustard in the face with his steel fist, which crushes his mask and in the process knocks him unconscious. The victorious Tetsutetsu lies down on the ground and regains his breath.[26]

Itsuka and Tetsutetsu head back to the facility with Mustard in tow. After Katsuki Bakugo is caputured, the Vanguard Action Squad withdraws from the battlefield, ending the attack. Mustard is arrested thanks to Itsuka and Tetsutetsu.[27]

Quirk and Abilities

Steel (スティール Sutīru?): Tetsutetsu's Quirk allows him to turn his body into steel, which gives him a great defensive ability. He can also use it offensively to increase the strength of his unarmed attacks. Upon losing an arm wrestling match he mentions that he should have had more iron that morning, possibly implying that his quirk strength is fueled and affected by his diet containing iron.
