The Fireside Babies Show

The show were they continued the events after Agent Doof, Isabella and the Fireside Girls are all babies, and they keep doing their job like they were real scouts as babies and babysit as well.

Van Stomm Squad Adventures

She makes an appearance as a baby in Season 1 when Home Guy went to their dimension. Later she made an recurring appearance in Season 2 as a teenager (after Act Your Age).


Phineas Flynn

She has romantic daydreams about Phineas and believes she will one day marry him or Ferb, but she never says that to him. She married Phineas in Phineas & Isabella's wedding and had April as their daughter.

Adam Williams

Isabella likes Adam. She, along with Phineas, Ferb & Candace finds Adam funny and thinks of him as their brother. She was fastinated with the way Adam designs his weapons. In Don't go to sleep, Phineas & Isabella got hit by Adam's tranqulizer dart and got put to sleep.

Ferb Fletcher

Isabella is best friends with Ferb, likely because he's the stepbrother of her crush, although she seems to get annoyed when Ferb goes with Phineas goes. Along with Candace, she has outright stated that Ferb is Phineas' stepbrother ("Rollercoaster"). Unlike her time with Phineas, Isabella shows no romantic interest in Ferb although she does like him. However, after time-traveling to the future, she learned that she might marry either Phineas or Ferb ("Phineas and Ferb's Quantum Boogaloo"). Upon this discovery, Ferb turned around and winked at Isabella, who was stunned at the possibility that she may marry someone else other than Phineas. This may indicate that Ferb may harbor a bit of affection for Isabella, or that Ferb just fancies himself a ladies' man ("Thaddeus and Thor"). It is also possible he was simply teasing her. Ferb is slightly irritated and gets mad when Phineas gets all of Isabella's attention and praise for being a superhero ("The Beak"), but it can be just the thought of him being the one who controls the lower half and saves Danville from the falling sign, but Phineas gets all the attention. When they were stranded on the uncharted island, Ferb listened while Isabella talked about Phineas not noticing her and offered her a handkerchief when she started crying. He knows about Isabella's crush on Phineas and he also walked away when Phineas came to leave them alone. He may might not have any affection to Isabella however he knows he might get married with her. ("Phineas and Ferb Summer Belongs to You!", "The Doof Side of the Moon"). It is most likely that he does not have affection for Isabella since he has more affection for Vanessa Doofenshmirtz ("I Scream, You Scream"). Ferb has also demonstrated awareness of Isabella's affection for Phineas; after Ferb helped Phineas throw a party for Isabella, when Phineas offered her ice cream with Ferb, he left to have Phineas and Isabella have some alone time together. Isabella was pleased and both bumped fists. ("Happy Birthday, Isabella") It is very plausible that Ferb did this because he knows that either he or Phineas will marry Isabella and he doesn't have any romantic feelings for her.

Kyle Broflovski

In the episode Phineas & Ferb go to South Park, Kyle Broflovski grows a huge crush on Isabella, and faints after Isabella says her catchphrase to him, Stan, Cartman & Kenny. She eventually develops a romantic relationship with Kyle, all while Cartman makes fun of them, saying "You two are like Stan & Wendy if they were Jews!". The two can't handle Eric's mockery & punch him. Kyle & Isabella eventually break up & Kyle admits he was having a lot of fun with Isabella.
