Phineas Flynn

Phineas Flynn is a fictional character and one of the two title characters from the animated television series Phineas and Ferb. He is voiced by Vincent Martella. Phineas, along with his quiet but intelligent stepbrother Ferb Fletcher, stars in the A-Plot of most episodes.

The series concerns Phineas and Ferb's attempts to avoid boredom by finding something new to do for each day of their summer vacation, often with many other neighborhood children. The activities they devise usually involve outlandish contraptions, including roller coasters, haunted houses, roller rinks, and a backyard beach etc. which Phineas and Ferb design and build cooperatively. Phineas's sister is Candace Flynn, who tries to reveal their outrageous creations to their mother, but to no avail.

Phineas comes from a blended family. The creators chose this arrangement because they considered it underused in children's programming as well as from creator Jeff "Swampy" Marsh's past experiences in one. As a character, Phineas has received positive critical response, with one reviewer describing him and his stepbrother as a "comical pairing." Phineas appears in Phineas and Ferb merchandise, including plush toys, t-shirts, and a video game.
