Duck Tales

The show featured the adventures of Scrooge McDuck and his great-nephews. It premiered on September 18, 1987 and ended on November 28, 1990 with a total of four seasons and 100 episodes

Plot:

The nephews, who were originally living with their uncle Donald, are left in Scrooge's care when the former joins the Navy.

Though Scrooge is the richest duck in the world, he constantly tries to find ways to increase his wealth. Many episodes involve protecting his wealth from villains who want to rob Scrooge of all his money. The prominent recurring antagonists in the show include the Beagle Boys andMagica De Spell who are always finding ways to rob and swindle Scrooge and his nephews. Scrooge's nemesis in the show is Flintheart Glomgold, who always tries to devise plans to dethrone Scrooge McDuck from his "Richest Duck in the World" title. 

A few of the stories also surround Scrooge's "Number One Dime" which is the source of Scrooge's good luck and wealth. Scrooge keeps the dime in a glass jar in his money vault, and constantly protects it from the villains on the show.

The show's second season saw the addition of characters Fenton Crackshell and Bubba Duck. Along with them came stories that generally shifted away from the globetrotting plots of the first season, and revolved primarily in the contemporary setting of Duckburg. Episodes would feature either Bubba or Fenton but rarely both.

Although Scrooge and his nephews were the show's main characters, some episodes focused on other characters like Launchpad or Gyro. 

Characters:

The main characters of the series, who appear in almost every episode, are Scrooge McDuck and his grandnephews Huey, Dewey, and Louie. Scrooge McDuck is a serious businessman, the richest duck in the world, a tightwad who accumulated a fortune by being "smarter than the smarties, and tougher than the toughies". Despite his harsh business ethics, Scrooge is caring to his family. Huey, Dewey, and Louie are Scrooge's great-nephews, who are left in his care during the entire length of the series. Although fairly hyperactive, the nephews are also clever and intelligent.

The series also features a mix of established characters carried over from the comics, as well as new ones created for the show. Scrooge's household also consists of his butler, Duckworth; Mrs. Beakley, a nanny hired to look after Huey, Dewey and Louie; and Webby Vanderquack, the granddaughter of Mrs. Beakley.

Initially, recurring characters included the absent-minded inventor Gyro Gearloose, the heroic but not too bright pilot Launchpad McQuack and the loyal but somewhat foolish Doofus Drake. During the second season, Bubba, a caveduck from the past, and an accountant, Fenton Crackshell, who had the dual identity of Gizmoduck, were added to the cast.

Other minor, but notable characters include Donald Duck, who left Huey, Dewey and Louie in Scrooge's care at the start of the series; Gladstone Gander, Scrooge's inexplicably lucky nephew; Scrooge's old flame, Glittering Goldie; Merlock, a powerful magician who served as the movie's main villain; and Dijon, a thief who worked either on his own or for Merlock.The show's primary villains consist of characters Magica De Spell, Flintheart Glomgold and the Beagle Boys. Although they are all financial threats to Scrooge in one way or another, they each have different motives: Magica wants Scrooge's Number One Dime to complete her magic spell, which will enable her to take over the world; Glomgold wants to replace Scrooge as the "Richest duck in the world"; and the Beagle Boys want to rob Scrooge of his fortune. While the comics originally depicted Glomgold as a native of South Africa, his origin was changed to Scottish descent just like Scrooge. New villains created for the show include Ma Beagle, mother of the Beagle Boys, and Poe De Spell, Magica's brother who has been transformed into a raven.
