Phineas Flynn

Phineas Flynn is one of the titular characters of Phineas and Ferb and is a major supporting character in The Disney Club. He and his step-brother Ferb Fletcher often spend most of their time building crazy inventions to make everyday as fun as possible, and often aid his sister Candace Flynn and her friends with some of their creations.

Personality
Phineas's most notable trait is his incurable optimism, constantly looking on the brighter side of things. He's also extremely smart, creative, persistent, and able to endeavor in immensely large projects and activities with the help of his step-brother. His hospitality is a driving force behind many of his plans. As intelligent and industrious as he is though, he's often oblivious to the emotions and intentions of those around him, sometimes even walking casually up to someone who clearly has ill intent.
