Jane, Quinn, and Helen are all voiced by the same actress, Wendy Hoopes.
Daria often describes her perceived cynicism as unabashed honesty. Appropriately, the name "Daria" is Greek and means "upholder of truth."
In a 2017 interview with Entertainment Weekly, series co-creator Susie Lewis gave an (apocryphal) account of where the characters are presently: Daria moved to New York City and works as a writer on a late-night talk show; Jane also lives in New York City and is still friends with Daria, works as an artist, and married an archaeologist; Trent is a bartender and still plays in a band; Jake and Helen are retired; Quinn has triplets and is estranged from her husband, and runs a YouTube channel about desserts and skin care; Brittany and Kevin married, Brittany works as a television weather girl and cheerleading coach while Kevin is a stay-at-home dad.
The character Daria was conceived as a dry-witted comic foil to counter Beavis and Butt-head's stupidity on Beavis et Butt-Head (1993).
Daria does not appear in the 2011 Beavis et Butt-Head (1993) revival. However, it is mentioned and acknowledged that she moved away.
