- “Like that, only worse.”
- ―NegaDuck after demonstrating his missle blaster to his cohorts
Negaduck is one of two villains from the Darkwing Duck television series and comic. The first was a manifestation of Darkwing Duck's evil side created by Megavolt's tronsplitter while the second and more well known version is an evil twin of Darkwing from a parallel universe known as the Negaverse. He first appeared as the leader of the Fearsome Five during the two-part Justice Ducks Unite episode.
As the archenemy and "evil twin" of Darkwing, not much is known about Negaduck's place of origin. A possible clue is that he rules the Negaverse, a parallel universe similar to Darkwing's home of St. Canard where evil reigns supreme. He refers to the Negaverse as his "secret hideout", which can only be accessed through a portal within the hollow shell of a papier-mâché cake inside a local bakery in the original St. Canard.
In addition to his own crimes, Negaduck is known to lead a band of villains he has dubbed the Fearsome Five, which also consists of Megavolt, Reginald Bushroot, Liquidator, and Quackerjack. Despite not having any powers of his own, he maintains an iron grip on the group's leadership through his intelligence and sheer ruthlessness and he doesn't like his Minions.
Negaduck occasionally has taken advantage of the fact that he greatly resembles Darkwing Duck by attempting to frame his good counterpart by committing crimes while disguised as Darkwing. This once came back to haunt him after instigating the public to put a price on Darkwing Duck's head and an angry mob mistook him for Darkwing Duck in different clothes. He also takes pride in being known as Public Enemy #1 and was greatly incensed to learn that another villain named Dr. Slug had stolen the title from him, prompting him to go on a rampage in order to reclaim it.
Unspeakably ruthless, horrifically sadistic and completely devoid of compassion and remorse; Negaduck is evil personified. He finds insidious joy in the misery of even the smallest innocent creature, hates flowers, and loves skulls. Like any criminal mastermind; Negaduck's schemes usually revolve around complete conquest of Saint Canart and obtaining immense wealth, but at the very top of his list is destroying his arch-enemy Darkwing Duck. Or at the very least, making Darkwing's life as miserable as possible.
In the BOOM Studios comic series, he discovers Darkwing's secret identity and nearly killed him until the Crime Bots apprehended him. He later met Magica DeSpell and released alternate world versions of Darkwing and brainwashed them into doing evil (except for DarkWarrior Duck who was already evil).
Negaduck lacks any powers of his own but makes up for it with his sadistic temperament and penchant for destructive weaponry, i.e. chainsaws, flamethrowers, bombs, and even a nuclear missile.
