Rodrigo (Phineas and Ferb)

"Don't worry, little platypus agent. When I'm through here, you'll no longer have to battle this inept loser anymore. Because, you see, I plan to get rid of both of you!"

- Rodrigo revealing his true intentions to a captured Perry

Rodrigo is the hidden main antagonist of the Phineas and Ferb episode ''Minor Monogram. ''

He was voiced by guest star Jorge Garcia.

Role
He was an exchange student studying in the art of evil science, assigned to being mentored by the local Danville mad scientist Heinz Doofenshmirtz, who has been making plans of taking over the Tri-State Area. In the episode, he is first seen when Doofenshmirtz shows him around his lab until the arrival of Doofenshmirtz's daughter Vanessa, who has broken up with her boyfriend Johnny (because he thinks a video game is more important than her). After Vanessa mopes about her failed relationship with Johnny, Doofenshmirtz cheers her up by suggesting that she stop going for the bad boy types, to which Vanessa happily responds that she's only attracted to the bad boy types because of her father's reputation as an evil scientist, even hugging him to prove the point. Upon hearing this, Rodrigo starts to show some interest in Vanessa through flirting, finding her to be quite unique in general, and in return, Vanessa shows some affection for him.

While Doofenshmritz is lecturing Rodrigo, Doofenshmirtz's nemesis, Perry the Platypus, arrives to battle him again. However, expecting Perry's arrival, Doofenshmirtz traps him in a boot stuck into the floor. Despite being surprised to see this, Rodrigo questions about the usage of the boot, stating that Perry might get out there easily and fight Doofenshmirtz. He suggested that he can come up with a better trap in hopes of which Doofenshmirtz could critique on. Seeing that there might be a point, Doofenshmirtz agrees to let Rodrigo create the new trap. While doing so, Rodrigo secretly confesses to Perry that he is planning to get rid both him and Doofenshmirtz, much to Perry's shock.

After Rodrigo finishes the trap, Perry (being unable to escape from it) attempts to warn Doofenshmirtz about Rodrigo's true intentions, but Doofenshmirtz doesn't understand him (since Perry can't talk). It was then Doofenshmirtz announces his latest scheme: he has created and installed two enormous propellers in opposite sides of the Tri-State Area, hoping to use them to physically dislodge the Tri-State Area from the face of the Earth and raise it into the sky where he will refuse to return it until he becomes its leader. Doofenshmirtz then activates the controls to the propellers, which suddenly dislodge the Tri-State Area from the Earth as planned, which has really impressed both Rodrigo and Vanessa (who finds this to be cool). Seeing that Doof's plan is going extremely well, Rodrigo reveals his true colors as he betrays Doofenshmirtz by trapping him next to Perry, and Vanessa is unable to help because she's wearing the same boot trap. It was then Rodrigo announces his true goal: he will manipulate the propellers at separate angles, which will literally tear the Tri-State Area apart and kill thousands of civilians. Rodrigo also confesses that he plans to use the imminent cataclysm as an example to demoralize others from trying to stop him from achieving his lifelong goal of world domination, much to the disgust of Doofenshmirtz and Perry. Rodrigo even tried to get Vanessa to join him, but she angrily refuses and berates Rodrigo for betraying her father. Unperturbed by Vanessa's refusal, Rodrigo grabs the controls and attempts to manipulate the propellers into splitting the Tri-State Area apart, laughing maniacally. However, he is knocked out from the controls by the arriving Monty Monogram (the son of Perry's boss Major Francis Monogram), who then beats up Rodrigo with the usage of acrobatics.

After the Tri-State Area is returned back to its proper place by a freed Perry, Monty ties up the defeated Rodrigo into a chair, leaving Perry to deal with him. Taking on Doofenshmirtz's advice, Vanessa decides to stop going for the bad boy types and starts focusing her attention towards Monty. It is unknown what happened to Rodrigo afterwards, though it may be implied that he was arrested and taken into O.W.C.A. custody for his attempt to destroy the Tri-State Area.
