Dorian

Dorian is an orphan from the Danville orphanage, though he (and Jagold) spends most of time on the street, making money by playing flute.

Personality
Dorian, though parentless, is a smart boy. He is friendly towards everyone, especially Gretchen, whom he has a crush on.

Story
At the age of 0.5 year, Dorian appeared on the orphanage's terrace, along with the letter saying

"Dorian, take care."

The orphanage took Dorian and raised him. With his nice attitude, he befriended his co-orphans very quickly, especially Jagold, whom he founded a flutist band with. By the age of 12, Dorian found and befriended a wild sparrow, whom he named Spear.

One day, Dorian and Jagold met Phineas and Ferb, who asked them for flute lessons. Dorian and Jagold agreed, and so the whole gang met at the Flynn-Fletcher backyard (along with Buford, Baljeet, Isabella, Fireside girls and Irving), where Dorian and Jagold taught the audience how to play flute in the form of a song. After this, Dorian and Jagold participated in many of the Big ideas.

Appearance
Dorian has green eyes and dark brown hair. He often wears the orphanage "uniform" - a brown tunic, black belt, grey shoes. However, when he goes to streets, he wears a black T-shirt and brown shorts.

Jagold
Jagold was Dorian's first friend and the two are the only members of Dorian's street flutes. Dorian and Jagold share a close bond and are like brothers.

Phineas and Ferb
Dorian is a friend of these two and taught them to play flute.

Gretchen
Dorian has a crush on Gretchen, yet both are unaware of this crush. It is well possible that these two will later get married, though they won't have kids.

Spear
Spear is Dorian's only pet and thus they're very close. Over years, Dorian gained Spear's trust.
