Daphne Blake is one teenager in a group of four mystery-solving teenagers who was a character in the widely loved and adored animated series Scooby-Doo.  The group consisted of Fred, Daphne, Velma, Shaggy, and their Great Dane named Scooy-Doo.  Daphne is known for her long red hair, her sense of fashion, although all her outfits are purple, and for her ability for fall into danger.  In fact, her friends make fun of her and call her Danger-prone Daphne as she was the one in the group who most often got kidnapped, gagged, and tied up being left in a dark room somewhere.

Aside from her stereotypical “damsel in distress” portrayal, she is also very smart.  Although not as smart as Velma, Daphne was able to solve her problems and get out of trouble with adding a bit of fashion flare.  In later episodes, Daphne is shown unlocking locks and doing other tasks with unpredicted items that she had in her purse.  

It is assumed that Daphne comes from a wealthy family, although this has never been confirmed, and it is also assumed that Daphne and Fred have a love interest in each other.  This has been flirted with since the start of the series, but it also hasn’t ever been proven.
