- For the original incarnation, see Elizabeth Blake.
Nan wears a purple shirt, blue pants, she is tall, she wears a hat, and a green hanckerchief. Her hair is significantly longer than her daughters and the red is noticably more faded but other than that she is identical to Daphne and her other daughters.
Although Nan is unbearably beautiful like her daughters, she is sweet, kind and caring (at least on the surface). Deep down she is selfish and vain, an example of this is when she was unwilling to go out in the dark to pick up her daughter from a dangerous place, but she was willing to go out in the dark to take notary lessons (despite not knowing what a notary is). She is deeply disappointed with her youngest daughter apparently believing that she went wrong with her, mostly because Daphne does not take out too much money to go shopping (at least from her mother's perspective). She goes as far as saying she sometimes wished she had a boy instead. She also wants Daphne to be more like her older sisters, who all have successful high profile careers. She also set up her daughter with Rung Ladderton in hopes of furthering Daphne's social standing.
Scooby-Doo! Mystery Incorporated
She and her husband came to get Daphne out of jail. Daphne chose this moment to announce that she and Fred were engaged to which she appeared shocked. Then later showed up again after the Freak was caught, to take Daphne home.
She was one of the Dandy Highwayman's "victims". In actuality she, like the other women, wished to simply get away from her boorish husband and liked having someone to talk to for a change.
In the new timeline, she approved of Daphne's engagement to Fred and was helping to plan the wedding. She thought more highly of Daphne than her other underachieving daughters.
- Nan's name was only known through the show's end credits until The Secret Serum, when she was referred to by name.
- Out of all the episodes she has appeared in, The Creeping Creatures and The Secret Serum are the only ones in which she wasn't with Barty; she also had a bigger role in the latter due to her being a prime suspect thoughout.
- The player of Scooby-Doo! Mystery Incorporated Crystal Cove Online will recieve a trophy of Nan Blake if a costume is bought.
