Aunque no hable mucho, es igual o más listo que Phineas. Suele ser el que planea y construye. Es la mano derecha de Phineas. La posibilidad de que no hable se puede deber a que sea tímido. Sabe hablar varios idiomas.
Familia
Phineas Flynn: Phineas y Ferb son aparentemente inseparables, pues hacen todo juntos y hacen el mayor par a los mejores días de cada campo. Phineas es el soñador del dúo y viene con todos los planes. Ferb normalmente va a las grandes longitudes para ayudar mecánicamente.
Candace Flynn: Aunque Candace sea su hermanastra, trata a Ferb como si en realidad fueran hermanos. Ayudó a arreglar la cara de Candace en la película que filmaron, también filmó la canción que le cantó a su madre. Candace siempre reta a Phineas, jamás a Ferb, por lo que se puede deducir cierto distanciamiento.
Linda Flynn: Es la madrastra de Ferb, aunque Linda trata a Ferb como si fuera su hijo y Ferb también la trata a ella como si fuera su madre. Es esposa de Lawrence Fletcher y madre de Phineas Flynn.
Lawrence Fletcher: Lawrence es el padre biológico de Ferb. Él y su padre son del Reino Unido y tiene una fuerte conexión con el acento británico. Tienen una relación normal de cualquier hijo tiene con su padre con la salvedad de que Ferb no habla mucho.
Perry el Ornitorrinco: Es la mascota de Phineas y Ferb. Aunque Perry se comporte de manera normal, tiene una doble vida como un agente secreto concido como "Agente P".
Los Primos de Ferb: Son los primos biológicos de Ferb, aunque se ven como simples chicos, lo humillan por creer que ya no se siente británico y se burlan de él por no saber jugar fútbol soccer.
Habilidades
Ferb tiene una habilidad increíble para la mecánica y construcción, casi nunca necesita ayuda para algo. También parece ser capaz de tocar una variedad de instrumentos a partir de la guitarra, bajo, batería, teclado, y trompeta. En algunas ocasiones se le a visto cantar, la cuales han sido las veces que más a hablado.
