Clyde Fletcher is a nice, well minded Kid. He is the son of Isabella and Ferb. He has a lot of disabilities there are to many to list here. Clyde is named after the Announcer at Phineas's award ceremony in Switzerland Clyde Bekernem. Clyde has 2 younger siblings and a twin. The reason why he has dark red hair is because before Ferb and Isabella dated Isabella dated Phineas, whom she had her first 18 kisses with, and she has Phineas in her, so that's why he has red hair. One of Clyde's siblings are Menntor Fletcher. Clyde's favorite toy is a doll that you can put makeup on.
