Katie Clarke has been drawing since she could hold a pencil, focusing on character-driven storytelling. Growing up, she believed she was going to be a film director, having made and edited her own movies since the age of 9 under the alias K.C. DeMille. She wrote her first full-length screenplay at 13. Her storyboards started to morph into graphic novels, which she hopes to finish and publish one day. Her stories follow strong female leads, one of whom, Maxx Cullen, is an assassin-for-hire. Katie’s interest in fighting techniques and styles for her stories brought her to Girls Who Fight, where she plans to become as skilled and lethal as her protagonists.

Having grown up in a Northern Irish family, Katie has been taught how to stand her ground and fight back, but has seen that not all girls are fortunate enough to have the same knowledge. She wants to change that by helping Girls Who Fight grow, so women and girls have a better chance in the world.

Katie is studying Graphic Design with an advertising major, honing her film and illustration skills on the side.
