Daffy Duck's character shifted from a hyperactive screwball in the 1930s-40s to a greedy, self-centered rival of Bugs Bunny, a reinvention largely credited to Chuck Jones.

The Chuck Jones website explicitly states that although Daffy was created by Tex Avery, Chuck Jones reinvented Daffy's persona as a greedy, self-centered duck, as exemplified in Rabbit Seasoning and Ali Baba Bunny. The Simple Wikipedia article notes that over the years, Daffy changed from a screwball and heckling character to greedy and a jealous character. This transformation is central to understanding Daffy: the early Daffy was pure anarchic energy, while the later Daffy is defined by his inability to accept Bugs Bunny's popularity and his relentless, often self-destructive pursuit of the spotlight.
