FERB.

Ferbs "Ferb" Fletcher is one of the two main protagonists in the animated television series Phineas and Ferb. Voiced by British actor Thomas Sangster on Phineas and Ferb and American actor David Errigo Jr. on Milo Murphy's Law and Candace Against the Universe, with a singing voice by series composer Danny Jacob, he was created by Phineas and Ferb co-founders Dan Povenmire and Jeff "Swampy" Marsh. He first appeared in the show's pilot episode, "Rollercoaster". Ferb was born on February 29. Ferb and his step-brother Phineas Flynn spend their days during summer vacation from school striving to have fun. They are featured in the majority of episodes as the A-Plot constructing large scale inventions or taking part in other outlandish activities. Ferb, an engineering genius, allows Phineas to do most of the talking for the pair and is "more of a man of action." When Ferb does speak, it is almost always a single sentence. In a conversation in the future time of "Phineas and Ferb's Quantum Boogaloo", it is revealed that he was at Camp David. Ferb was named after a set-builder named Frank Leasure, a construction foreman on several Star Trek properties and a friend of Povenmire and Marsh. His wife Melinda, an artist on The Simpsons and King of the Hill nicknamed him "Ferb". In "Vanessassary Roughness" Ferb explains that his name is short for something, but he didn't get a chance to say it. On Twitter, Povenmire announced that Ferb was actually short for "Ferbs". He cares for Vanessa Doofenshmirtz (daughter of Dr. Heinz Doofenshmirtz) and saves her in the same episode when she gets tangled up and a lawn mower almost gets her, but he is able to save her with a giant tool which appears to be an exaggerated version of a Swiss Army Knife. In "Summer Belongs To You" Vanessa asks Candace what Ferb is short for; Candace realizes she doesn't know herself what it is short for. In the fourth season episode "Act Your Age", he as a teenager appears to be in a relationship with Vanessa. Ferb's design is based on a rectangle and also shaped like an "F" and is inspired by the style of late animator Tex Avery. As a character, Ferb has been critically well-received and appears in several pieces of Phineas and Ferb merchandise, including toys, T-shirts, and video games.
