Princess Daphne is the daughter of The King Ethelred and an unnamed Queen. Her background belongs to the damsel in distress stock: A beautiful maiden coveted by many princes and knights, her heart belongs to the Kingdom's champion, Dirk the Daring.
In the games she wears: a headband with a miniature crown; a loose-knit gown over a black 1-piece bathing suit; high heels, and a necklace with a matching bracelet.
Daphne has brief appearances during the game, seen at the beginning of some sequences carried by a shadowy figure and yells "save me!". She appears in the final level of the game, giving Dirk directions to use the magic sword and slay the dragon.
In the TV series her character and role are far more developed. She is an adventurous, protective, rational, independent, nice, compassionate, even-tempered, selfless, sweet-tempered, daring, athletic, polite, heroic, nurturing and educated character, often eager to abandon her princely pose and joins Dirk and Timothy in their adventures. Also, her attire is less revealing, wearing a proper princely dress.
At the start of the game, 10 years have passed after her adventure with Singe. Daphne and Dirk are married and have over a dozen children. However she is again captured, this time by the evil wizard Mordroc, who wants to enslave her with the Death Ring.
At the end of the game, the Ring transforms her into a monster, but Dirk saves her by removing it from her finger. She then falls into a coma, but Dirk cures her with a kiss.
Mordread, Mordroc's evil witch sister, imprisons Dirk's homestead into an orb on her staff. Dirk however was not in the house, so he begins pursuing Mordread to restore his home, and Daphne inside it.
In the comics, like in the TV series, Daphne is a very adventurous character, if not violent and bloodthirsty. Dirk mentions that she loves beheading enemies and monsters, like the ferocious Begelsum monsters ravaging the western glade, Gorgons and the moaning fricket. She rides the foal Rustspot.
She rode with Dirk near Taerwan's Lake, when Singe captured her. She is given a sexy gown, and put it in the Bubble of Helotry; the magic bubble has the purpose to drain her intelligence, and from the feisty princess, to become the bimbo of the original game.
According to a pre-production concept sketch, Daphne will appear as a 16-year old tomboy with her hair cut short. The state of the movie is by 2017 unknown.
