"Ferb, I know what we're gonna do today!" - Phineas's catchphrase
Phineas Flynn (voiced by Vincent Martella) is one of the main characters from the TV series Phineas and Ferb.
Phineas is a young boy who has an English step-brother named Ferb and a teenage sister named Candace. Phineas likes to make the most of every day, and so he teams up with his friends and Ferb to create big schmes and adventures to make every day of summer worthwhile. That way, he'll have something to talk about when he returns to school. His friend Isabella has a crush on him, but he doesn't usually know.
- Phineas, along with Ferb, Candace, and Isabella (and possibly Buford and Baljeet), will join the Bugs and Daffy's Adventures team in Bugs and Daffy's Adventures of Phineas and Ferb: Across the 2nd Dimension. They are of great importance to the team, as they can help with technological problems.
