She is a lot like a mutant from X-men, born with her powers. She can control the shadows from moving them, making them solid or air, and can summon creatures within the "Shadow plain". She has different skills linked with her powers, a few examples are able to shadow project (A lot like spirit projection) and can enter peoples mind with the shadows always in our heads. Her powers can be draining and she over does it sometimes. She is skilled in hand to hand combat and with boa staff and katana. A lone wolf for a long time, but when she's in a team, the team is before her own life. Willing to give her life to save others. 

Plots I love the ones that the past coming back to haunt, a over all bad guy controlling pawns, and a lot of twists and turns.
