Jo

Silver hair, red eyes, carries twin Desert Eagles and is known as "The Angel from Hell." She has superhuman abilities from her artificial creation, usually followed by the appearance of a purple glowing tattoo on her left arm and shoulder blade. They resemble wings and are often called "The Wings of the Devil" and will glow when Jo is put under a lot of stress when fighting. Jo also puts Meg over anything else, which she stated when telling Meg that she fights for her only. When she is not fighting, she enjoys watching horror or gore related movies.
