Evil Carl

By accident, he fell under the influence of Doctor Doofenshmirtz's Ultimate Evil-inator and used his status within the OWCA to launch a full scale attack on the Tri-State Area. However, he was momentarily slowed down by Perry's interference before Perry strangely disappeared ("Where's Perry?").

His plans to conquer the Tri-State Area were severely damaged as Perry locked the control panel and only his paw print could unlock it. To this extent, Carl goes on a hunt for the lost platypus and winds up in Africa, cornering Agent P in the unexplored gorge. However, Agent P does not give into evil Carl and engages his robot duplicates in a full scale battle with aide from the African wildlife, a confused Candace, Major Monogram and Doofenshmirtz before Doofenshmirtz uses his newly built -inator to turn Carl back to his normal self. He then returns home with Monogram and Doof, but not before being promoted to the "title" of "paid intern" ("Where's Perry? (Part Two)").
