Netunia, Olimpia and Parceiro were specially created to be part of Dickie's gang by Brazilian Disney Studios, which belongs to Grupo Abril. That was the first (and probably only) time that a teen gang was introduced in the "Duckverse" (a nickname commonly used to refer to the Disney Ducks Universe). Dickie and her four close friends possibly are studying journalism at some university of Duckburg, because of her clear connection to the reporter career, which was shown in various comic stories. Donald and his nephews never appeared in those stories with Dickie's teen gang. Dickie Duck's first American appearance was in the Gemstone run of "Donald Duck Adventures", in the story "Return to TNT", in a cameo. Just like Moby Duck, Dickie is one of the few secondary characters who was cast as a small figurine in two different Italian collections by De Agostini.  0.0. Duck and Mata Harrier are a secret-agent duo. They were created by Dick Kinney and Al Hubbard for the Disney Studio Program, a unit that produced Disney comics for foreign publication. Their first story was "The Case of the Purloined Pearls" published in 1966. 0.0. Duck's name is a play on "007" (a.k.a. "James Bond") while Mata Harrier's one is an obvious play on "Mata Hari". They appeared for the first time in the story "The Case of the Purloined Pearls", where they fought against agents of the evil organization "BLONK". Then the agents of this organization became the traditional rivals of 0.0. Duck and Mata Harrier in their subsequent stories, most of them created by Brazilian cartoonists. 0.0. Duck owns a small dog ironically called Wolf. The latest comic appearance of 0.0. Duck, Mata Harrier, Wolf and agents of BLONK was in the 20th adventure of the comic subseries Tamers of Nonhuman Threats, called "Things that Go Blonk". Even 0.0. & Mata's subchief, created by Brazilian comic artists in 1975, appears in this one. Belle Duck is a plus-sized, tall and elegant duck lady. She appeared for the first time in "Belle Corners the Coin Collection" with drawings by the cartoonist Al Hubbard, first published in "Topolino" #591 (March 1967). In this story, Scrooge meets Belle again 40 years after their last meeting.
