Half-Cold Half-Hot

Half-Cold Half-Hot is a Quirk used by Shoto Todoroki.

Description
Half-Cold Half-Hot stems from combining Shoto father's Hell Flame ability and his mother's ice power through a Quirk marriage. As a result, it is perfectly divided between the right and left side of Shoto's body.

Right-side: Using the limbs on the right side of his body, Shoto can drastically lower temperatures and freeze anything he touches. This ability is very potent, as Shoto can swiftly freeze entire buildings and streets, as well as create large waves of ice instantaneously. He possess great control and direction over the ability, as he can create restrict the ice to avoid fatally freezing someone, as well as using precision attacks to freeze only certain portions of his targets body.

Shoto is also capable of using the molding the ice into certain shapes to support himself. He consistently created blocks of ice to his rear to avoid being blown out of bounds during his battle with Izuku. In that same fight, he also created a stairs of ice he could run up to elevate himself. During his battle with Katsuki, Shoto created a moving wave of ice that he surfed to recover from being thrown.

Prolonged usage of his right-side can lower his body temperature to dangerous level. When this occurs, Shoto's body gets covered in frost and his ice attacks lose their effectiveness. His maximum output brings him to his temperature limit almost immediately.

Left-side: From his left, Shoto can drastically increase temperatures and release scorching hot flames. When Shoto ignites his flames, the blaze covers his arm and the left side of his head. He is able to shoot out the blaze as streams of fire and send out short waves of it to protect himself from close quarters attacks.

Due to Shoto's animosity towards his father, he held off on using his left-side offensively for most of his life and doesn't have as fine control over it as he does his right as a result. His lack of control has made adjusting the temperatures of his flames is difficult for him. It is also possible for him to overuse his left, but the repercussions are not currently known.

Fortunately, Shoto is capable of using his other side to counteract the dangerous effects of which ever one he happens to be overexerting. He is also capable of activating both simultaneously, but lack of practice has made this awkward for him, and it dulls his movements.

Named Techniques

 * Giant Ice Wall (大氷壁): Shoto creates a huge, glacier-like wave of ice. This move is first used in his battle against Hanta Sero in the U.A. Sports Festival, but is unnamed until the End of Term Test. A variation of this move, slightly smaller in size, is shown in his battle against Katsuki Bakugo.
