The Drill Sergeant (voiced by Clancy Brown) is a minor antagonist in Phineas and Ferb, who controls the Smile Away Reformatory School and its prisoners. Though unnamed, the Sergeant poses a very real threat to Phineas and Ferb. He loathes imagination and creativity and, through his reformatory school, attempts to remove these things from the children that are sent to him. As such, he is a natural antagonist to the Flynn-Fletcher boys, who find themselves under his control when it appears that Candace has finally succeeded in busting them.

Methods

His methods range from the tedious (having his prisoners paint a small, plain box over and over again) to the cruel (solitary confinement and water torture). All methods are designed to discourage free thinking and the creative process. Although Phineas and Ferb remain strong through the early days of their confinement, the Sergeant succeeds in breaking them down into monotone, passionless drones. In an interview with Morty Williams, he refers to the boys as his "greatest success stories."

Role in the series

When Candace succeeds in rescuing Phineas and Ferb from the Smile Away Reformatory School, the Sergeant and his guards give chase. The Sergeant corners them on a cliff, but just as he is about to capture Phineas and Ferb, Perry and Dr. Doofenshmirtz appear atop a mechanical spider; Doofensmhirtz is defeated and the crumbling of his robot sends the Sergeant tumbling from the cliff to his (apparent) death.

It is later revealed that the busting of Phineas and Ferb and all subsequent events were a part of a dream sequence in Candace's mind. In the end, Candace's dream was all Perry's dream. Since the Sergeant only appeared in this dream, whether he exists in real life is unknown.
