to the regular universe
of St. Canard
in the Disney cartoon Darkwing Duck
In the Negaverse everything is the opposite of the "real" St. Canard. The city is rundown and polluted and a superhero team called the Friendly Four (composed of Megavolt, Bushroot, Liquidator, and QuackerJack) fights crime. Gosalyn Mallard is a perfect little angel. The Muddlefoots are corrupt, twisted people (with the exception of Tank who is a noble guy). Negaduck is the hero of the city. Basically, corruption and anarchy rule in the Negaverse.
The entry portal to the Negaverse is a large cake that exists in both worlds and was first seen in the episode "Life, The Negaverse, and Everything".
