In a world where over 80% of the population has superpowers known as Quirks, Aeron Dash stands out with his unique blend of speed and style. As a UA High School student training to become a Pro Hero, Aeron's Quirk, 'Sonic Fleet,' allows him to run at hypersonic speeds, creating sonic booms that he can manipulate. Despite his scrawny appearance and quirky fashion sense—often donning a mohawk and a mix of cardigans with varsity jackets—Aeron is determined to be the fastest hero alive. He struggles balancing hero duties with his love for music, often seen wearing headphones to tune out distractions. Raised in a small town, Aeron moved to the city to attend UA, driven by a desire to prove himself and protect others. Though he often trips over his own feet, his heart and determination keep him racing toward heroism.
