Bambietta Basterbine is a slender young Quincy with long, straight dark brown hair, brown eyes, and a sadistic disposition. She takes pleasure in mercilessly slaughtering her enemies, subjecting them to her sadistic whims before callously ending their lives. Despite her cruelty, Bambietta despises being abandoned by her fellow Sternritter, considering herself their self-proclaimed leader, and resorts to explosive destruction when faced with abandonment.
