Perry the Platypus is a former supporting protagonist-turned tertiary antagonist of the Duo-Franchise continuity. He eventually redeemed himself and sacrificed himself to destroy McDuck's legacy for good only to have his DNA replicated into the second Perry. It was revealed that Ace Savvy had resurrected the pistachion and managed to convince him to join the dark side once more setting him up as one of the tertiary antagonists of Duo-Franchise: Big City Style (alongside Bubbles Utonium, another hidden cultist). He is voiced by Dee Bradley Baker.
