Phineas and Isabella's Son[]

Pierce Flynn[]
Parker and Pierce are the best of brothers! They love to hang out, build, and sing together. Pierce is quieter than Parker, but not to the extent of Phineas and Ferb.
Olivia Flynn[]
Parker loves his big sister, Olivia. They have a great time inventing together, though they get on each others nerves. (Olivia being a worrier.) She always tries to keep him safe and that annoys Parker.
Lexi Flynn[]
Lexi and Parker spend a lot of time together, as she won't let her brothers do anything without her! She always says, "Watcha doin? because I'm going to do it to!" Parker rolls his eyes and explains what the plan is for the day.
Zander Flynn[]
Zander and Parker get along, but don't hang out much as Zander is only two.
