Daisy Duck is the very beautiful love interest and the girlfriend of Donald Duck, in many ways their relationship mirrors that of Mickey Mouse and Minnie Mouse but with some notable differences.
Daisy has constantly been portrayed as more sophisticated than the often rough and tough Donald, due to this she often finds Donald's temper to be a source of conflict, yet she also has a temper on her, despite this and her beauty, Donald is quite stricken with her and she in turn shows affection towards him.
Daisy herself has been around since 1940 and resembles Donald Duck himself (much as Minnie Mouse resembles Mickey) - though she has feminine eyelashs and a large bow.
