Enji Todoroki (AU Adolescente) 》⁷《

His appearance as a teenager was:

During his teenage years, Enji Todoroki stood out for his imposing appearance and determined air. His bright red hair, which fell messily over his forehead, was already beginning to be a distinctive mark, although less well-groomed than in his adulthood. His build was athletic but still developing, showing the first signs of the musculature that would characterize him later. His intense, determined gaze, with eyes that seemed to burn with the ambition to surpass All Might, already conveyed his unwavering determination. He often wore simple clothing, possibly a school uniform or training outfit that highlighted his physique. Still unscarred, his youthful face lacked the wear and tear that the years and his future obsessions would bring, but his posture and attitude already reflected the weight of his goals.

as it is in the UA:

Enji Todoroki, as a student at UA, would have been one of the standouts of his generation due to his incredible potential and determination. His Quirk, Hellflame, was already extremely powerful, and he likely excelled in both combat and tests of endurance. However, his obsessive focus on being number one likely made him more competitive than collaborative. This might have caused some friction with his peers, who saw him as a brilliant student but difficult to approach due to his serious nature and almost boundless ambition. As a student, Enji would have been someone who teachers recognized for his talent, but also as someone who needed to learn about teamwork and emotional control. Although he failed to achieve his goal of surpassing All Might at such a young age, his time at UA would have been key in laying the foundation for his later success as a pro hero.
