"I became a special effects artist to join the nations of this earth together in peace and hope."
Clive Addison is a special effects artist who makes an appearance in "Nerds of a Feather".
Clive Addison is Phineas and Ferb's special effects hero. He has worked on at least two movie franchises so far, Space Adventure (Speckies), and Stumbleberry Finkbat (Finkies). Throughout the Science fiction and Fantasy convention, all Phineas and Ferb want to do is meet him, but the war between Sci-Fi and Fantasy prevents Phineas and Ferb from every opportunity that presents itself.
After learning about the war from Phineas, he helps them unite the Speckies and Finkies through the use of special effects. After uniting the two groups, Clive tells Phineas and Ferb that they showed him the best special effects show ever and that the two of them are going to have amazing careers in special effects, and if they wanted that, they could give him a call in ten years and he would hire them both. Ferb says what he would love to do is direct, to which Clive replies, "You and me both," implying that he would rather be a director than a special effects person. ("Nerds of a Feather").
