Aloyse von Roddenstein

Skills
Rodney is very skilled in ballet, as shown in the episode "Nerdy Dancin'". Hе may also be skilled at inventing in a way similar to Dr. Doofenshmirtz. However, his only inventions revealed so far were an electric fan he dubbed, the 'Fog Clearer-Inator', which was destroyed by Doofenshmirtz's 'Eradicate Rodney's Inator-Inator ("Robot Rodeo"), and a 'Make-Everything-Evil-Inizor', which is simply based on the design of Doofenshmirtz's 'Make Everything Evil-Inator'. ("Bullseye!") Also, when Rodney learned that Doofenshmirtz had created an -inator that has successfully moved the Earth away from the Sun, he used Doofenshmirtz's blueprints to create himself an -inizor (which is just ten times the size and strength of Doof's inator) that will bring in a new Ice Age. ("Phineas and Ferb: Save Summer") However, despite his skills, Rodney is shown to be physically weak in combat, as Doofenshmirtz was able to defeat him with a mop. ("Phineas and Ferb: Save Summer")
