Theresa Scully is a Spanish woman who appears in the episode 'The Mark of Xero'. She is a love interest of Dodgers. She is voiced by Tasia Valenza.
Background[]
She first appears to ask Duck Dodgers for help in freeing her people from Commandante Hilgalgo. Hilgalgo appears and she says he's the one who's making misery. Hilgalgo repeats the same phrase Dodgers used and when Theresa ask Dodgers if he has anything to say, he simply shows her a little magic trick. Theresa, unimpressed, simply says "all flash, no substance". Theresa is taken into custody and sentenced to hang as a trap for Xero.
Cadet disguised as a friar gains entry to Theresa's cell and tells her not to worry before he reveals himself.

Watercolor sketch of the lovely Señorita Theresa (voiced by Tasia Valenza), the heroine of “The Mark of Xero” episode of the “Duck Dodgers” TV show. Drawings like this were made prior to boarding and served as character models, 2005.
