Story

On the planet of Puckworld, the inhabitants are anthropomorphic ducks. Hockey is not only the most important sport on Puckworld, it's a way of life. On this planet, legends are told of a Duck named Drake DuCaine, who rid the universe of an evil anthropomorphic reptilian race called Saurians. Some Ducks do not believe the legends, but according to the them, DuCaine did so with a seemingly normal goalie mask that transforms into a high-tech mask. With it, DuCaine sent the Saurians to a mysterious dimension, known only as "Dimensional Limbo".

As it turns out, the legends are true. Many centuries later, some of the Saurians escape Dimensional Limbo and return to Puckworld with an armada of robotic attack ships. The group of four is led by the last of the Saurian Overlords, Lord Dragaunus. They attack and invade the planet, enslaving the people of Puckworld so that they can produce more weapons to conquer the universe. However, a resistance is formed by Canard, a brave duck who acquires The Mask of Drake DuCaine out of a tomb in the mountains. With it, the Ducks can see through the Saurians' invisibility cloak. Canard forms a band of Ducks to fight Dragaunus, called The Resistance. The Resistance destroys Dragaunus's fortress (called the Master Tower.) However, Dragaunus and his forces escape in their ship, the Raptor. The Saurians open up a dimensional gateway and attempt to escape through it, just as they had done to escape Dimensional Limbo. However, Canard and the others follow him into the portal with their aircraft, the Aerowing.

Dragaunus attempts to get rid of the Ducks inside the portal by attacking them with an electromagnetic worm that will grow until it can swallow the Aerowing. In a desperate attempt to get rid of the worm, Canard sacrifices his own life by throwing himself to the worm. The plan succeeds, but at the price of Canard being devoured by the worm and never being seen again. Luckily, Canard leaves behind The Mask, giving it and the leadership of the team to Wildwing Flashblade, his best friend. Both the Raptor and the Aerowing leave the portal and enter a different dimension, landing on Earth. The Ducks meet Phil Pomfeather, a human who becomes their manager and makes them a legitimate NHL team. Their arena, only known as The Pond in the show, has a hockey rink that doubles as a landing pad for the Aerowing above and has a formal HQ below. On Earth, the Ducks and Dragaunus continue their fight, although there are other villains that also challenge the six Ducks.
