DuckTales
When Donald Duck decides to join the US Navy, he enlists his uncle Scrooge McDuck to look after his nephews, Huey, Dewey, and Louie. Although reluctant to do so due to their hyperactivity, along with his continual pursuit of increasing his wealth and maintaining harsh business ethics, he eventually warms to them upon seeing how smart and resourceful they are, and takes them into his manor as well as a number of adventures. In addition to them, the show features frequent appearances by Gyro Gearloose, an established comic book character, as well as guest appearances by Donald in the first season – this was either a full appearance, or in a cameo scene when Scrooge and his nephews read letters he sends to them, and a few minor appearances by Scrooge's old flame, Glittering Goldie, whose character was adapted from the comic books. The show introduced new characters to the Duck universe; while some were minor including: the nanny Mrs. Beakley, whom Scrooge hires to babysit the nephews; Mrs. Beakley's granddaughter Webby; Scrooge's pilot Launchpad McQuack; Doofus Drake, an admirer of Launchpad and a close friend of the nephews; and the McDuck Manor butler, Duckworth. The second season later introduced three new additional characters as part of the show's stories: "caveduck" Bubba Duck and his pet triceratops Tootsie; and Fenton Crackshell, Scrooge's personal accountant who secretly works as a superhero named Gizmoduck.
Donald Duck in comics
In both cases the stories presented Donald's personality as having multiple aspects that would surface according to circumstance. Or as Barks would say later: "He was sometimes a villain, and he was often a real good guy and at all times he was just a blundering person like the average human being." Adding another note of realism was the fact that Donald could end up being either the victor or the loser in his stories. And often even his victories were hollow. This gave a sense of realism to Donald's character and the characters and situations around him. His nephews accompanied him in those stories and Barks also gave many aspects to their personalities. In some cases they acted as the mischievous brats Taliaferro had introduced, often antagonizing their uncle. In some cases they got in trouble and Donald would have to save them. But in others they proved remarkably resourceful and inventive, often helping their uncle out of a difficult situation. But most of the time, they would appear to have developed a deeper understanding of things and level of maturity than their uncle.
