2nd Dimension Peter the Panda, or better known as Peter the Pandaborg, 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 Peter the Panda.
Just like his counterpart, 2nd Peter was once an O.W.C.A. agent, but he and the other agents have been enslaved and transformed into ruthless Animal-Borgs 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, Pandaborg secretly enforced the Doofenshmirtz family's rule of the Tri-State Area for 5 years.
Back to the 2nd Dimension
Two months following 2nd Doof's arrest and the Norm Bots' destruction, Pandaborg aids several of his fellow Animal-Borgs to capture the reformed Platyborg, though this was foiled by Resistance. However, Pandaborg manages to track down 2nd Ferb and brings him over to 2nd Charlene, who supposedly turns him into a cyborg. This allowed 2nd Charlene to trap Platyborg, 2nd Phineas, and 2nd Candace in her lair and free 2nd Doof, since 2nd Candace had to bring him to her penthouse (as any Doofenshmirtz relatives can be allowed to enter by passing through the sensor system).
Eventually, 2nd Ferb revealed that he staged his transformation as a cyborg and aided his siblings into escaping and fighting off the evil Doofenshmirtz couple and the Animal-Borgs. As a result, all of the Animal-Borgs are freed from their evil programming, except for Pandaborg, who ends up being smashed by a falling pillar after being defeated by Platyborg. However, Pandaborg manages to get himself out from the rubble and escapes with the Doofenshmirtz family on a hover car driven by 2nd Vanessa's boyfriend Tony Marzulo. It's completely unknown if Pandaborg was ever taken into custody and reverted to normal or lived the rest of his days as a fugitive alongside the Doofenshmirtz family.
Just like the rest of the Animal Borgs, Pandaborg is fitted with robotic armor, this one consisting of a gray robotic suit that includes a robotic red left eye for pinpoint accuracy to detect targets, and a double-excavator weapon fitted on his right arm that can chomp off cement and zap targets to unconsciousness. He is also capable of flying, as he hovers around to search for intruders as he helps his fellow Animal-Borgs bring a detained Platyborg to 2nd Charlene's penthouse. Also, just like his original counterpart, Pandaborg is very strong in combat, as he proved to be a match against Platyborg during the Resistance's attack at 2nd Charlene's penthouse.
