The Fearsome Five are a group of villains led by Negaduck. They first appeared together in the two-part episode Just Us Justice Ducks. They returned in the episode "Life, The Negaverse And Everything". In the Eponymous dimension, four good versions of Megavolt, Bushroot, Quackerjack and Liquidator are known as the Friendly Four who are against Negaduck. Pirate versions of them (most likely their ancestors) appeared in the episode "Darkwing Doubloon".
