Ferb Fletcher

Ferb Fletcher is the son of Lawrence Fletcher and a unknown woman, the step-son of Linda Flynn-Fletcher, the step-brother of Phineas Flynn and Candace Flynn and one of the titular characters of Phineas and Ferb. He is a British Fletcher child currently living in Danville and the best friend of his step-brother Phineas. He also has a crush on Dr. Doofenshmirtz' daughter Vanessa.

He was born in England to Lawrence and an unknown woman sometime in the late 1990s. Sometime after this, his mother either died or left Lawrence and so after this Ferb and his father moved to America where Lawrence got married to a woman named Linda Flynn who had two children she had from a previous relationship, a daughter named Candace and a son named Phineas whom Ferb became friends with.

Ferb rarely talks, saying only a few words and on some occasions a full sentence. However, despite his unintelligence, he can also be very smart.

He is voiced by Thomas Brodie-Sangster.
