SCP-239 seemingly has the ability to do whatever she expresses a will to do. Put simply, the subject can do anything that she truly wants to do on a basal psychological level as long as she is conscious. Fortunately, she only seems to be able to affect herself and her immediate surroundings; therefore, "If she can see it, she can change it." It would not be the most prudent course of action, however, to try to test how powerful she can be. She seems to be able to create and affect living matter.
