Beagle Boys
The Beagle Boys are a group of fictional characters from the Donald Duck universe. They are a gang of crooks who constantly try to rob Scrooge McDuck and were created by Carl Barks.
In the comics the individual Beagle Boys are refered to by their prison numbers, printed over their chest, with the three most common numbers being 176-167, 176-671, and 176-761.
On Duck Tales they have names and different personalities like Bigtime, Burger, Bouncer, Baggy, Babyface, Bugle, and Bankjob. The usual character combination is Bigtime, Burger, and Bouncer, and sometimes Baggy or Babyface, Bugle, and Bankjob. Their Leader is usually Bigtime or Bankjob or their mother Ma Beagle.
According to Don Rosa's Life and Times of Scrooge McDuck, Scrooge first met The Beagle Boys in his Mississippi riverboat days. Those Beagle Boys included Blackheart Beagle and his three sons. Scrooge first met the modern Beagle Boys during Christmas 1947, which was when he first met his grandnephews Huey, Dewey, and Louie and met his nephew Donald for the second time. Since then the Beagle Boys have been a constant threat to Scrooge's huge money bin.
Sometimes they team up with other villains such as Magica De Spell, Black Pete, Mad Madam Mim, or hire out their services to Flintheart Glomgold or John Rockerduck.
Sometimes they antagonize Super Goof or Mickey Mouse or some other characters from Walt Disney's comic books.
