Django Brown is a recurring character in Phineas and Ferb. He is one of Phineas and Ferb's friends who can surf and, so he believes, put his foot behind his head (painfully). He isn't very bright. He is also a very good artist and participates as the announcer in Phineas and Ferb's chariot race. ("Greece Lightning")
Django was born in America and is the son of the artist Beppo Brown, who is famous for his work in making giant creations, from refrigerators to dental floss. ("Oil on Candace"). His mother was never introduced.
Django makes a cameo appearance at the Backyard Beach as one of the surfers that Buford removes from the surfing competition. ("Lawn Gnome Beach Party of Terror") He was shown at the "Summer Rocks" music festival playing rock and roll on a violin and wearing a kilt. ("The Baljeatles") He's a fan of the Space Adventure series and sings in Our Movie's Better Than Yours. ("Nerds of a Feather")
Putting Foot Behind Head: Django tries to put his foot behind his head, but he isn't flexible enough, so when he tries it at Phineas and Ferb's cirque, he gets hurt. ("Jerk De Soleil")
Artist: Like his dad, Beppo Brown, he is very good at art. His latest work was a picture of him and his dad he wants to show to him, but he thinks it is too small in comparison to his dad's art to show to his dad. The picture, later, is honored by his dad putting it on the front of his giant fridge. ("Oil on Candace")
Django Brown has not been seen in many episodes, but has an ability to surf clumsily ("Lawn Gnome Beach Party of Terror"), almost put his foot behind his head ("Jerk De Soleil"), is a very good artist ("Oil on Candace"), a violinist in ("The Baljeatles"), and singing ("Nerds of a Feather").
Django only appeared in fifteen episodes so far. Six of these were in Season 1, five were in Season 2, one in Season 3, and three in Season 4.
He is named after series creator Jeff "Swampy" Marsh's son Django. (Dan Povenmire Correspondence on the Phineas and Ferb wiki)
In the Phineas and Ferb Laughapalooza Joke Book, it is mentioned that Django Brown is a hippie.
The costume Django wears in "Nerds of a Feather" resembles the UNSC's standard battle suit and the Federation's MI battle suit.
The rifle that Django is seen loading in "Nerds of a Feather" resembles a Fusionfall rifle weapon.
The cereal Django is seen eating in "Jerk De Soleil' may be Krispy Korn Flakes in Phineas' House.
In "Oil on Candace", when Django's Unpainted Desert picture was was about to be washed away, the sun in the picture disappears.
Django makes a small cameo in "Phineas and Ferb The Movie: Across the 2nd Dimension"; when almost all of Phineas and Ferb's most potentially violent/destructive creations are revealed, Django can be found in the window of the robot shark from the Season 3 episode "The Belly of the Beast". Django's appearance may have been a joke on how he rarely appears in the series, or it may just have been because the creators were strapped (on short amount) for reoccurring characters due to the low named-character to attack/vehicle invention ratio.
