He was the eldest son of Rei Todoroki and the Pro Hero Endeavor, with his younger siblings being Fuyumi, Natsuo, and Shoto. Dabi was driven insane due to Enji's neglectful and selfish actions, becoming a Villain to enact revenge. He became affiliated with the League of Villains, a former member of the organization's since disbanded Vanguard Action Squad, and later one of the nine lieutenants of the Paranormal Liberation Front.Dabi was a reasonably tall, pale young man of slim shape but somewhat muscular build, described to be in his early twenties. He had spiky white hair that didn't pass his neck, and bangs that hung low over his eyes, which were thin, turquoise, and heavily lidded. Dabi's hair was dyed black before revealing his true identity. As a child, Toya had a round face and unruly crimson hair spiked up in tufts around his head, falling down his forehead in uneven bangs, though due to inheriting his mother's genes, his hair slowly turned white as he grew older.[5] He wore a plain gakuran jacket and usually wore a neutral expression, as shown in a few of his family's photos.[6] Due to his premature birth, he was shorter than his two younger siblings, Fuyumi and Natsuo, though it wasn't until after his growth spurt did Toya become around the same height as them. After losing control of his Quirk and waking up from three years comatose, Toya had grown taller, and his hair had become spikier, with him now resembling more of his appearance as an adult. Toya's burn scars were also present, with the missing parts of his body having to be replaced by regenerative tissue, although they were not as severe as they are now, and not yet attached to his skin via piercings.[7] His most striking features were undoubtedly the patches of gnarled, wrinkled, purple skin that covered much of his lower face and neck, all the way down past his collarbone, below his eyes, around his torso, and on his arms and legs due to him losing control of his fire Quirk at age 13, engulfing him in flames. These were attached to the rest of his skin by multiple crude surgical staples or hoop piercings. He had several silver (gold in the manga) cartilage piercings in both ears and a triple nostril piercing on the right side of his nose. Upon closer inspection, he also lacked earlobes on both sides of his ears. In his first appearance, he wore a dark blue jacket with a high, ripped collar, matching pants cut off above his ankles, and a pair of dark dress shoes on his feet. He also had a plain white, scoop-neck shirt, below which a gray belt with a circular pattern wraps around his waist, and a brown leather satchel attached at the back. Upon joining the Vanguard Action Squad, Dabi's apparel was updated, now consisting of a large dark blue knee-length overcoat with two large metal cuffs at the end of each elbow-length sleeve and a white stitch design on each of his shoulders; the coat had three ripped hems, granting the appearance of four coattails. His shirt and belt stayed the same, but he replaced his pants with a larger pair of a darker color, and his shoes with black boots.Toya was very energetic and boisterous as a child, and he wanted to learn as much as he could from his father. Because his father, Enji, had emphasized that he would be the one to surpass All Might since childhood, Toya became obsessed with fulfilling that dream, becoming just as stubborn as his father to become the next number one hero. Toya was not unmotivated upon learning that his body could not safely handle his flames, becoming upset and frustrated when his father refused to train him anymore. Despite Enji telling him to focus on something else and find a new goal to pursue, Toya was insistent that he could still live up to his father's dream and continued to train on his own, burning himself in the process. Toya described his goal as a fire that his father lit within him that would not go out and that he could not bring himself to ignore, highlighting how his childhood dream became an unhealthy obsession. However, Rei believed that Toya just wanted his father's attention and proof that he wasn't a failure, something that became more apparent following the birth of Shoto, who had inherited the Quirk and strength that Toya lacked. Toya bitterly blames his mother for being created. Toya bitterly blames his mother for being created. Toya's obsession would go on to make him further unstable, not caring about the damage his Quirk training was doing to his own body while shrugging off concerns from his sister and mother, saying that his younger siblings lived in a different world than him. At one point, Toya even lashed out and attacked his mother and an infant Shoto with his Quirk when his father refused to look at him, leading to Enji's decision to raise Shoto away from his siblings. Being aware of the Quirk Marriage of his parents,
