She can pick a target and steal their eyesight (view through their eyes). The victim usually isn't aware that they are being spied on. Her main ability would be forcing her victims to stare at a certain point and be unable to turn away from it, that person will become oddly enamored with the object. She can also 'freeze' herself or lock her into place to make her blend into her surroundings as long as she's standing still. She can mess with her opponents optic nerve and change how they perceive their surroundings.
