So here’s Koba.
Koba is the right hand of the secretive crime lord Maw, rival of Three-Eyes. Koba is intelligent and extremely dangerous, but suffers from poor impulse control. She rarely allows a chance to fight or hurt people pass her by.
In addition to her superb martial arts skills, she possesses the ability to control the blood of anyone she is touching. This allows her to manhandle even much larger opponents and break them like toys. Three-Eyes gutted her once, and she carries a grudge.
I’m still testing some variations for this design, which you can find within the spoiler tags below.
