Harribel is calm, taciturn, level-headed, and analytical, preferring to not engage in combat. Before Harribel became an Arrancar, she was a Vasto lorde as most of her body and face was covered by white Hollow bones, and her weapon was part of her arm, but her hair and eyes were exposed. Her mask wrapped around her head, with an extremely long and thin shark tail hanging from the back of her head. There were also pointed protrusions from her shoulders and elbows.
