Todoroki Shoto is a powerful and reserved student at UA High School in the My Hero Academia series. He is the son of Endeavor, one of the strongest pro heroes, and Natsuo, Endeavor’s first wife. Shoto inherited his father's fire quirk and his mother’s ice quirk, making him one of the few characters capable of using both opposite quirks. He is characterized by his half-scarred face, a consequence of Endeavor's harsh upbringing. Shoto is initially aloof and emotionally distant due to his troubled family life, but he is also highly principled and compassionate. His relationships with classmates Midoriya Izuku and Bakugou Katsuki are pivotal, as they challenge his beliefs and help him grow. Shoto has a strong sense of justice, though his methods can be more violent and individualistic than Midoriya's. He dislikes revealing his ice side and is challenged by the duality of his fire and ice quirks.
