2nd Dimension Peter the Panda (known as Peter the Pandaborg) is an 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.
In the episode, 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 Charlene Doofenshmirtz (the wife of the notorious Tri-State Area dictator, 2nd Heinz Doofenshmirtz), similar to how Perry the Platyborg became 2nd Doofenshmirtz's robotic enforcer. Two months following 2nd Doofenshmirtz's arrest and the Norm-Bots' destruction, Pandaborg aids several of his fellow animal cyborgs to capture the reformed Platyborg, though this was foiled by the efforts of the Resistance. However, Pandaborg manages to track down 2nd Ferb and brings him to 2nd Charlene, who supposedly turns him into a cyborg, which allowed 2nd Charlene to trap Platyborg, 2nd Phineas, and 2nd Candace in 2nd Charlene's lair. Also, as part of 2nd Charlene's plan, it allowed 2nd Doofenshmirtz to be free, 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). However, it turns out that 2nd Ferb faked being turned into a cyborg and aided his siblings into escaping and fighting off the evil Doofenshmirtz couple and their animal-cyborgs. After the battle, all of the animal cyborgs 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 notorious Doofenshmirtz family on a hover car driven by 2nd Vanessa's boyfriend Tony Marzulo.
