|~ Rodney commenting on his son Orville for his assistance.|
Orville von Roddenstein is a minor villain of the Phineas and Ferb series. He is the son/apprentice of the infamous mad scientist Aloyse 'Rodney' Von Roddenstein.
Orville only made a silent cameo in the episode "A Real Boy", where Rodney is giving a video message to his rival Heinz Doofenshmirtz to gloat about the progress of his new -inizor. Rodney also admits that he had Orville to help him out with the -inizor and that he happens to be as evil and smart as his father. Rodney further gloats of having a son that has some aptitude for evil to taunt Doofenshmirtz of having a daughter who usually goes shopping, but Doofenshmirtz is unmoved by this as he berates Rodney for trying to make him believe that daughters are useless.
It is unknown what happened to Orville afterwards, even in the 2014 special "Phineas and Ferb Save Summer", when his father was arrested for his attempt to send the Earth into a new Ice Age that could've endangered billions of lives. As such, Orville's fate is left undisclosed.
- He bears some resemblances to Mandark from Dexter's Laboratory, as they are both kid villains wearing glasses and have a desire to be evil.
