Dr. Heinz Doofenshmirtz is the recurring villain in Disney's animated series Phineas and Ferb, which first aired in 2007. Voiced by co-creator Dan Povenmire, he became a fan favourite for his absurd inventions and self-defeating schemes, and short clips of his voice spread widely through YouTube edits, TikTok, and meme soundboards. The character's mix of menace and incompetence keeps the audio instantly funny, even for viewers who only know him from short clips rather than full episodes.
