Summary: Phineas decides to travel back in time to meet his biological father Zephyr.
The article is actually called “Phineas and Candace’s dad”. If your character who you think is their father isn’t there, put your fanfic into the Phineas and Ferb Fanon Wiki. If you already did, you may edit the page.
I actually wanted to put Perry the Platypus, too. But I haven’t put a fanfic there yet. I hope I’ll put one someday.
