S.H.U.S.H. is a super-secret spy agency headed by J. Gander Hooter. S.H.U.S.H. is usually shown handling cases involving the terrorist attacks led by F.O.W.L.
S.H.U.S.H. agents are known for their meticulous by-the-book methods and are careful to abide by the law. When their brand of justice is proven ineffective, Director Hooter will call in Darkwing Duck, whose vigilante style and "off the payroll" status proves beneficial.
Darkwing has, more often than not, been utilized as a cheap delivery service. He will protect S.H.U.S.H. packages with his life, only to find out the contents contained a stapler or a cassette of Greatest Polka Hits.
