Huey, Dewey and Louie

Personalities
Huey, Dewey and Louie are Donald Duck's mischievous nephews, who have a usual rivalry with him. While they each have a distinct character trait, they share some similarities. All three are shown to be crafty and troublesome and usually think alike. In some earlier cartoons, they would often argue amongst themselves and have been shown to whine and cry. All three also share joy in tormenting Donald for their own amusement. However, this is sometimes an act of revenge from a prank committed by Donald instead. In the comics, they are children, while in Quack Pack, they are older, and have more distinct personalities.

Huey
Huey is the oldest and leader of the trio and the bravest of the bunch. Huey is never afraid of a challenge and never backs down. Huey makes sure Dewey's plans are in line and makes sure Louie doesn't fall behind. He wears a red shirt. Although ultimately kind, he is often seen as a troublemaker in the group, and arguably the most aggressive.

Dewey
Dewey is the brains of the trio. Dewey is very smart and well-organized. Dewey loves to think of new ideas and ways to have fun. On occasion, he shows he has the talents of an inventor as well. Dewey is also shown to have leadership potential, as he took control as leader on a few occasions. He wears a blue shirt.

In early cartoons, Dewey would sport a tangerine shirt instead of his now-trademark blue, which wouldn't appear in Dewey's animation days until DuckTales.

Louie
Louie is the nicest of the trio. He is gentle, carefree, laid-back, and notices things others miss easily, showing a particularly creative thinking. Louie is not very loud like his brothers. He can sometimes be absent-minded and a little bumbling, but when it's needed is shown to be just as clever as his brothers.

While Louie wore his now-trademark green shirt in the earliest of cartoons, he sometimes sported a yellow shirt.
