Holly McGuire

Holly McGuire is a secret agent who also happens to be Ferb's childhood friend from London.

Personality
Holly seems quiet and shy to anyone who isn't her friend. To her friends, however, Holly is spunky, unafraid, talkative, and a little crazy. To her fellow secret agents, she is the Commando, and has high authority among them.

Relationships
Phineas Flynn- Phineas regards Holly as "cute" which makes Isabella jealous, as she believes she looks the same as Holly. Holly often asks about Phineas in her letters to Ferb.

Ferb Fletcher- When both she and Ferb were the age of four, Holly gave Ferb a transmitter due to the Director's orders. It is still unknown how she gave Ferb the transmitter, because in The London Situation, she refused to tell Ferb. It is shown that Holly really cares for Ferb, and Ferb feels the same way.

Isabella Garcia-Shapiro- When Isabella first met Holly, she disliked her because Phineas called her cute and she believed that she looked the same as Holly. However, after getting to know her better, Isabella decides she can try to be Holly's friend.

Candace Flynn- Candace thinks Holly's job as a secret agent is awesome, and admires her because of that.

Buford Van Stomm- Holly doesn't know Buford yet.

Baljeet- Holly doesn't know Baljeet yet.

Life in London
Holly has lived in London with her dad ever since she was born. At the small age of three, Holly became recruited to become a secret agent, because she outsmarted the Director himself when she met him in the park. When she turned four, her father took her to meet Ferb, and the two became fast friends. The Director, however, noticing an opening to America, told Holly to give Ferb a transmitter when the time was right. The time was right when Ferb told Holly that he was moving to America. She gave him the transmitter(in some fashion) as a goodbye present.

She lived a sad life after Ferb left. Her father eventually died in a car accident, and the Director took her in. Holly devoted her life to becoming the best secret agent, and eventually was promoted to Commando. Her fellow secret agents respect her, but they still call her names like Director's pet.

It was only by chance that Holly was recruited to stop Dr. Doofenshmirtz from capturing some Danville citizens. What she didn't know was that Ferb was one of the Danville citizens.

And that her life was going to change for the better...
