In another galaxy exists a planet populated entirely by humanoid ducks. Dubbed "Puckworld" by its inhabitants, it is an icy planet, perfectly suited to the Ducks' favorite pastime, Hockey. For the citizens of Puckworld, hockey was not simply a sport, but a way of life, occupying virtually every aspect of day-to-day existence.
Legend has it that centuries ago, during an invasion by a reptilian race called Saurians, a duck named Drake DuCaine became the planet's savior over the Saurians' Overlords. The legend tells that DuCaine did so with a high-tech goalie mask. With it, DuCaine sent the Saurians to a mysterious "Dimensional Limbo".
The last of the Saurians escape Dimensional Limbo and returns to Puckworld with an armada of robotic attack ships. The group of four is led by the last of the Saurian Overlords, Lord Dragaunus, who is assisted by his minions Siege, Chameleon and Wraith. They invade the planet and enslave the people of Puckworld. However, a resistance was formed by Canard, who has found The Mask of Drake DuCaine. With it, the wearer of the Mask could see through the Saurians' invisibility cloaks. Canard forms a band of Ducks to fight Dragaunus. The members of his team consists of Wildwing, Nosedive, Tanya, Duke, Mallory and Grin. They go on a mission to destroy Dragaunus's fortress the Master Tower and free the planet from the Saurians' control. While the mission is successful, Dragaunus and his forces manage escape in their ship, the Raptor. The Saurians open up a dimensional gateway to escape through but Canard and the others follow him into the portal with the Aerowing, intent on stopping them.
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. Before dying, Canard gave the Mask, and 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 in the Earth city of Anaheim, California. The Ducks meet Phil Palmfeather, 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.
