Dr. Aloyse van Roddenstein  (often referred to simply as Rodney) is a super-villain scientist from the animated TV series Phineas and Ferb.  He is a recurring villain on the series and occassionally appears in the background and often acts as a rival for Dr. Doofenshmirtz.

He is voiced by Joe Orrantia.


Dr. Roddenstein's past is largely unknown.


Dr. Roddenstein (full name Aloyse Everheart Elizabeth Otto Wolfgang Hypatia Gunther Galen Gary Cooper von Roddenstein), is a mad scientist from South Dakota who is something of a rival to Dr. Doofenshmirtz, though has joined him in his evil organization L.O.V.E.M.U.F.F.I.N.. His history is unknown, but he and Dr. Doofenshmirtz are often butting heads when it comes to taking over the world.  One of the few things known about his personal life is that he has a son, also capable of making "izers" (what her refers to his mad science-based weapons), though this is only according to him. 

After joining L.O.V.E.M.U.F.F.I.N., Roddenstein assisted in Dr. Doofenshmirtz plan to enter a dance competition to gain attention for their evil cause.  He also competed with Dr. Doofenshmirtz and other scientist in a competition to create an "Inator" (a shorthand for an evil invention) and won the first years competition but lost to Doofenshmirtz the following year.


Rodney is quite rude towards most other villains, often insulting fellow villains for being foolish or not evil enough.Despite, or perhaps because, their dislike of each other, he and Doofenshmirtz are very similar. While Doofenshmirtz ends all of his invention names with "-inator", Roddenstein ends all of his with "-izer".
