Doofenshmirtz's schemes and inventions are plans and devices created by Dr. Heinz Doofenshmirtz as a means of dominating and taking over the Tri-State Area or other locations. They are typically grandiose in scope, involving a complicated solution instead of applying a simpler, more practical method. One example is inventing a "wood magnet" when dynamite would be more effective and faster ("Are You My Mummy?").
The motivation behind their development is typically a need to exact revenge for an unpleasant incident in his life, or to resolve a situation that annoys him. An example of the latter is the plan to transport Big Ben from London to Danville instead of buying a larger clock because shopping for a clock would be too much of a hassle ("Elementary, My Dear Stacy").
The names given to the inventions tend to end in "-inator", with the notable exception of Shrinkspheria, one that Doofenshmirtz notes himself ("Mom's Birthday"). It is not known how he can afford to build all his inventions, though he does mention that he gets a large alimony check every month ("Got Game?").
His Schemes and Inventions are listed by episode.
Plus, most of his schemes backfire at Phineas and Ferb's work, destroying it or infecting it, leaving Candace without any evidence to bust the boys. One invention called the "Shrink-inator" infected Phineas and Ferb's projects twice. Plus, he always fogets to unplug it ("Does This Duckbill Make Me Look Fat?", "Let's Take a Quiz")
