My DC Academia

Barry Allen was only 4 years old when his mother was killed by the man in the yellow suit. At that young age, he swore to avenge her once he got his quirk. Unfortunately, that day never came, and he was forced to study to become a hero without a quirk.

However, one day, he received the means to become a hero that could defeat the man in the yellow suit

Oh, I forgot to mention, this is the story of how Barry Allen became the fastest man alive, and the world's greatest hero.
