Dolly Paprika was the Fantomius' partner in his infamous thefts. At first she is only briefly mentioned in the second Duck Avenger story by Guido Martina, until Marco Gervasio creates her a background.
Dolly Paprika's real name is Dolly Duck, a rich lady who, tired of the aristocrats and their snobbish ways, decides to follow Fantomius' steps. This doesn't mean she's insensitive; Dolly sincerely loves Fantomius, and gets worried when he elaborates particularly risky plans.
