Darkwing Duck is a little known crime fighter dying for a big break, and the publicity that goes with it. Yet when he gets on the trail of the infamous Taurus Bulba's latest scheme he gets into more trouble than he expected. Bulba has masterminded a scheme from within prison revolving around a powerful invention - the Waddlemeyer Ramrod, but is missing the arming code. Darkwing foils an attempt to kidnap the only living relative of the late inventor of the Ramrod, an orphan named Gosalyn.
Under Darkwing's care, Gosalyn ends up revealing the ramrod arming code in the form of a lullabye her Grandfather used to sing. But a newly escaped Taurus Bulba lures Darkwing out into the opening to both find his secret lair and turn him over to the police. Launchpad, Darkwing's biggest fan springs him loose, becoming his new sidekick at the helm of his fanmade superhero jet - the Thunderquack. They race to Bulba's flying base of operations for a final climactic showdown which ends in a shattering explosion around both Darkwing and Taurus. Later, a bruised and battered Drake Mallard (aka DW) arrives at Gosalyn's orphanage to adopt her.
Reginald Bushroot, plant scientist, only wants to make the world a better place to live, but his colleagues mock his passion for plants.

The owner of the local mini-golf, Lilliput, has invented a helmet that allows him to communicate with ants. He then uses a shrink ray to shrink the buildings and landmarks of St. Canard, using the ants to haul the now-shrunk buildings back to the mini-golf, where thay become part of the course. When DW discovers his secret, Lilliput shrinks him down a tiny size, smaller than an ant. DW now has to foil the villain's plot, and get back to normal.
Dr. Bushroot, trying to grow a wife for himself, accidentally creates a vampire potato. The Muddlefoot's go camping with Gosalyn hoping to capture a mysterious monster - ""Webfoot"". Darkwing and Launchpad track Bushroot into the country, where a strange truck driver named Duane tells them about the giant potato. Darkwing think's Duane is just crazy and doesn't listen, but when a bunch of hicks at a diner think DW is the vampire and try to kill him, DW has to prove he isn't one. As all this is happening, the vampire potato has turned Launchpad, Herb, Binkie, and Tank into zombies. Honker and Gosalyn finally convince DW that the vampire is real, but before he can kill it, Bushroot shows up to ""save"" his bride. Eventually, DW follows some advise Duane gave him and the potato is defeated, the zombies are returned to normal, and Bushroot threatens revenge.

SHUSH has given Darkwing Duck a simple case: Travel to Oilrabia and stop Steelbeak's schemes to steal their oil. Steelbeak's plan: flooding the place with his weather machine and attacking by sea.

A series of supernatural pizza topping thefts leads DW to the place that is home to St. Canard's mushroom production: McCawber Mansion.

Can he crack this mysterious case, or has the hero been bitten too hard by the love bug?
Morgana is using sleep sand to rob the citizens of St. Canard while they sleepwalk. When Darkwing steps in to set things right, he ends up in dreamland.

While pursuing the Fearsome Five (and therefore escaping the Muddlefoots and their boring ""Pelican's Island"" birthday party for Honker), Darkwing is thrown into a giant cake - which serves as the universal portal between his world and the Negaverse. In the Negaverse, everything is the extreme opposite of his world and Negaduck is supreme ruler, so Darkwing decides to use his new friends (The "Friendly Four") to change things a bit, which Negaduck does NOT like.
