Shoto Todoroki

Character
Shoto was initially shown as being aloof and distant from his class, with a cold personality that originated from his abusive childhood and complicated relationship with his powers. This demeanor majorly changed after the U.A Sports Festival Arc, when he came to terms with his fire quirk and one-sided rivalry with Izuku Midoriya. After this, he is seen socially interacting with fellow classmates and is relatively amicable, becoming part of "Dekusquad" and opening up more, though still pertaining to arrogant or impulsive aspects of his nature.
