Angela Lee and Natalie Gonzales Hills during their weigh in, ahead of their bout at the ONE: Pride of Lions fighting event

At first glance, Angela Lee looks like a normal teenager. But unlike her contemporaries, the 19-year-old spends most of her time inside a steel cage, beating up opponents twice her age.

Lee is part of a new generation of mixed martial arts (MMA) fighters from Asia, and has been turning heads along the way. Raised in a family of martial artists, Lee remains undefeated since her debut earlier this year against experienced Egyptian fighter Aya Saber. It was a bout that Lee ended in less than two minutes.
