Ferbs "Ferb" Fletcher is a British character on the animated television series Phineas and Ferb. He is the step-son of Linda Flynn and son of Lawrence Fletcher. Being a native of England, he speaks with an English accent. He is one of three children of the Flynn-Fletcher household among his step-siblings Phineas Flynn and Candace Flynn.
Ferb has fair skin, as well as thick, scruffy, and light green hair. His head is tall and rectangle-shaped, with a large cubical nose, and also shaped like an "F". He has dark blue eyes, one of which is larger than the other. He wears a light yellow polo shirt with a white collar and button, very high-waisted dark purple pants with a light purple belt, white socks, and black converse sneakers. After the 2-year timeskip, his appearance stays the same, except for the fact that his belt gains a buckle.
His outfit pretty much stays the same in Season 4 of Advanced Education, but in the Cipher's Law Arc, he wears a different outfit when outside. That outfit consists of a dark gray jacket over his yellow polo shirt, and his purple pants are baggy and are pulled down to his waist. On his feet, he wears a pair of green and white high-top converse sneakers.
Ferb was devised as a character devoid of ill will. Marsh explained, "It was important to us that [Phineas and Ferb] never did anything with any animosity. They never tried to get their sister in trouble or outsmart their mother and get away with it." Instead, he and his brother create things for the sheer enjoyment of it or to help out others ("and for the ladies"); for example, Ferb and Phineas carve Candace's face into Mount Rushmore for her birthday, set up a roller derby for a rematch race with his Grandmother Betty Jo's old rival, create a haunted house for their friend Isabella to cure her hiccups and make a super-computer to find out what to do for their mom after being so kind to them.

Ferb appeared in a few flashbacks of Season 2. In the Christmas Special of Season 4, He, along with Mabel, Phineas, Dipper, Perry, and Blendin went back in time with Andy and Molly to stop Tord, Al, and Sid from changing history in the Toy Story 3 timeline, in order to prove to the Time Police that the Davises are not responsible for the time anomalies caused by Tord's group before their timeline is erased. In Heroes United's Cipher's Law Arc, he goes on a camping trip with Phineas, Perry, Isabella, Dipper, Mabel, and Candace, and later meets up with Milo and Doofenshmirtz, and eventually Tom and co. He spends the entirety of Spring Break hanging out with our heroes while trying to fight off the infamous Bill Cipher. In Season 47, he returns and joins Tom and co. on a trip to Cape-Cod.
In the Dog Daze series, during the Park BB Arc, he helps Tom and the gang revert their friends back to their original bodies after having switched bodies with the Avengers from an alternate timeline. In the Milford Weekend Arc, He, along with his step-brother, pet platypus, and the Pines twins, stays in Milford with Tom and co. for a week before parting ways at the end of said Story Arc.
In the Senior Year episode "Thanks, But No Giving", Ferb had a very minor role, as he, along with his family was captured by the Larssons and put in a simulation. After being rescued, he returns home with his family. He returns in the episode "Dave & Buster's: The Third Visit", where they run into Tom and co. at Dave & Buster's and play a lot of games together. Phineas and Ferb are left in charge of their home after their parents left for yet another month-long trip. They were then called by Dipper and Mabel, who invited the two, along with Perry, to spend the weekend with them. They met up with Tom and co. at a diner, and since then they hung out together constantly, from staying over in Milford to watching a puppet show in Providence. After Perry went missing during his recent mission, the 4 kids teamed up and began a search for their beloved Platypus. They were eventually joined by Stewie and Brian, and they managed to build an interdimensional portal, with help from Stan & Ford and OWCA. They then entered the second dimension and rescued Perry and Caillou, and put Caillou-2 behind bars. Afterwards, They all got back together when Doof and Caillou's family were kidnapped by Doof-2, and used time travel to take him down. Once that was taken care of, they helped Perry gather the courage to confess his love to Doof before parting ways with Tom and co.
