Oz-Bezarius-Alice

Oz is the main protagonist of Jun Mochizuki's Pandora Hearts. Originally given life unintentionally by Lacie, Oz began his journey as a Chain with a joint consciousness spread between twin black rabbit dolls. Unfortunately, one of Oz's bodies was destroyed, and his second body was transformed by the Intention of the Abyss into a powerhouse Chain known as B-Rabbit. From here, Oz formed an Illegal Contract with Jack Vessalius and was forced to sever the Chains of the World and slaughter numerous people. In the end, Oz's guilt ended when Alice committed suicide and stole his powers and body as a disembodied soul, leaving Oz as a mere soul existing in Jack's body.
