Pinky the Chihuahuaborg

2nd Dimension Pinky the Chihuahua (better known as "Pinky the Chihuahuaborg") is a supporting antagonist of the Phineas and Ferb episode Tales from the Resistance: Back to the 2nd Dimension. He is an alternate reality version of the heroic secret agent Pinky the Chihuahua.

Backstory
Just like his original counterpart, 2nd Pinky was once an O.W.C.A. agent and belonged to 2nd Isabella Garcia-Shapiro. However, just like his fellow agents, he has been enslaved and transformed into a Animal-Borg by the evil 2nd Dimension Charlene Doofenshmirtz (the wife of the notorious Tri-State Area dictator 2nd Dimension Heinz Doofenshmirtz), similar to how Perry the Platyborg became 2nd Doof's robotic enforcer. Ever since then, Chihuahuaborg secretly enforced the Doofenshmirtz family's reign of the Tri-State Area for five years, and 2nd Isabella felt worried that he has been gone for a long time.

Back to the 2nd Dimension
2 months following 2nd Doofenshmirtz's arrest and the Norm Bots' destruction, Chihuahuaborg aids several of his fellow animal cyborgs to capture Platyborg, though this was foiled by the efforts of the Resistance. Chihuahuaborg would later aid in capturing Platyborg again (along with 2nd Phineas and 2nd Candace) in 2nd Charlene's lair as part of her true plan to free 2nd Doofenshmirtz (since 2nd Candace had to bring him along to get past the penthouse's sensor systems).

However, 2nd Ferb released his siblings and Platyborg by pretending that he was turned into a cyborg by 2nd Charlene, and the Resistance arrive to free the enslaved agents by using specialized fedora hats. 2nd Isabella attempts to use one of the fedora hats on Chihuahuaborg, but has difficulty of doing so. Fortunately, 2nd Phineas manages to get the job done for her, which finally freed 2nd Pinky from his evil programming and allowing him to reunite with 2nd Isabella. 2nd Pinky and other freed agents later attempted to hold both 2nd Doofenshmirtz and 2nd Charlene at gunpoint so that the Resistance could take them into custody. However, the couple's daughter 2nd Vanessa aids her family and Peter the Pandaborg (the only Animal-Borg ever to retain his evil programming) to escape by having her boyfriend Tony Marzulo to drive them away in a hover car.

Despite the Doofenshmirtz family's escape, 2nd Pinky is presumed to resume his life living with 2nd Isabella and her family.
