Stephanie Brown is the daughter of the supervillain Cluemaster, and became a vigilante known as Spoiler to try and atone for the misdeeds of her father. She has trained under Bruce Wayne, Batgirl, and Catwoman. She's cheerful, upbeat, and friendly, but kind of lacks a brain-to-mouth filter and is prone to blurting out things without thinking. She struggles with her self-confidence and feeling worthy of her place in the Bat Family, but she is devoted and skilled at what she does.
