Fearsome Five
From Multiversal Omnipedia
The Fearsome Five was a group of five of Darkwing Duck's worst enemies, founded by Negaduck, and based around the idea that if St. Canard's villains combined their forces they would be able to overcome their enemy. Unfortunately, Negaduck was a poor leader, and the villains often fought amongst themselves, usually leading to their downfall. In response to the group's formation, Gizmoduck started the Justice Ducks.
