Old Daphne was the disguise of Judy Reeves.
She looks like an older version of Daphne Blake
Scooby-Doo! Mystery Incorporated
She used plastic surgery (along with Brad) to look like an old version of Daphne saying that the Planispheric Disk destroyed Crystal Cove by speeding up time turning everybody to skeletons. This was to trick Fred into showing her where the Planispheric Disk was on a movie set of the destroyed city, while her husband tried to find it in the real city by listening to their conversations.
- Old Daphne along with Evil Fred are the first disguises that didn't consist of masks.
