Heinz Doofenshmirtz

Heinz Doofenshmirtz (also known as Doof for short) is the main antagonist of the Disney Channel animated series Phineas and Ferb. Voiced by the show's co-creator Dan Povenmire, he acts as the arch-nemesis of the eponymous brothers' pet and secret agent Perry the Platypus.

In the Mr. /co/lympus tournaments, Doofenshmirtz is best known for "Doofposting", a series of humorous posts that involves anonymous users roleplaying as the character telling his experiences related to the contest, just like how he tells his backstory in the actual show. He attained the status of an elite contestant during his 2019 run, where he lost to Hank Hill in the quarter-finals and ultimately placing eighth.

Heinz will make his return in the 2021 edition.
