Judy Reeves is the biological mother of Fred Jones, Jr., and a member of the original Mystery Incorporated who vanished twenty years ago in the Crystal Cove Caves. She is married to Fred's birth father, Brad Chiles, another member of the group. She is also Daphne Blake's original Mystery Inc. counterpart.
She and Brad make traps and solve mysteries under the assumed name of "Sternum and Sternum," and they have a TV show about themselves under that name. They invented the Flattenhower 8000.
She has short blonde hair and wears blue eye shadow. She wears pearl earrings and a pearl necklace, along with a sleeveless coral dress that goes halfway up her long neck.
After undergoing plastic surgery she looks like an older version of Daphne Blake. Professor Pericles couldn't be bothered to undo the surgery, so she was stuck with this appearance to the end of her life (until the reset).
Brad thanks Judy every time she volunteers a detail when he speaks. She seems rather unemotional about finally getting together with her long-kidnapped son. She showed some affection for her dog, Nova, and she is grateful to get back her locket that Daphne found.
When it comes to the Planispheric Disk, she and Brad are perfectly willing to steal from their own son, or even attempt to murder him.
