Big Sister Instinct: Much more obvious than in Candace-1. In fact, it is her primary obsession along with overthrowing Doof-2. Possibly Deconstructed, when she had to leave the first dimension kids on their own, making her own brothers of utmost importance above all. She does go back to save them, however.
Jerk with a Heart of Gold: Not exactly a jerk, but she's willing to sacrifice the first dimension protagonists to keep her own brothers safe, not to mention being reluctant to help the first dimension Phineas and Ferb at first until Phineas-2 pleaded with her. She later returns and saves the first dimension characters.
Informed Attribute: We never really see exactly how he "resists the Resistance" in spite of multiple references to it. He even accompanies the bona fide Resistance members on their mission voluntarily. This is much like how the first dimension Buford "bullies" the first dimension kids, but does not really do much to show for it.
Jerk with a Heart of Jerk: He appears to be feeling bad after Candace-2 betrays the first dimension protagonists, but he was mostly just regretting not getting his nachos.
Precocious Crush: To Candace-2. More evident than his First Dimension counterpart.
Rebellious Rebel: He got so good at resisting he started resisting the Resistance.
Hoist by His Own Petard: While being part machine gave him some advantages over Perry-1, during their climactic showdown his tail barb spears a turkey and the rigidity of his mechanical parts prevents him from getting it off. He is then defeated when the turkey ends up on his head and he backs into an electric socket, which shocks him through his metal body.
