Phineas Flynn is the main protagonist of the animated television series Phineas and Ferb. Voiced by Vincent Martella and created and designed by Dan Povenmire, Phineas first appeared along with the rest of the series' main characters in the pilot episode "Rollercoaster." Phineas, along with his stepbrother Ferb Fletcher, star in each A-Plot of every episode. The series concerns Phineas's attempts to avoid boredom by finding something new to do every day of the summer vacation. His sister's name is Candace Flynn, who tries to reveal their outrageous creations, but to no avail. It is also said in Phineas and Ferb's "Quantum Boogaloo" that he had won the nobel prize, as he was in Switzerland at the time for the "award ceremony". Phineas comes from a blended family. The creators chose this arrangement because they considered it underused in children's programming as well as from Marsh's past experiences in one. As a character, Phineas has received a positive critical response, with one reviewer describing him and his brother as a "comical pairing." Phineas appears in Phineas and Ferb merchandise, including plush toys, t-shirts, and a video game.
