Baljeet Tjinder

Baljeet is Phineas and Ferb's friend who helps them with their Big Ideas. He is an Indian boy who is perceived as always getting good grades and being bullied by Buford. He is considered a nerd and thinks that getting an F on a math test is the scariest thing known to man. He has moved here from India for his education. He can play the drums, and the guitar. Although it seems like his feelings make him want to do math, he actually just does alot of math, "the feelings come and go". His friends have nicknamed him Jeet.

Baljeet is great at math, passive, and very polite. He enjoys trivia, learning, and has a compelling need to get good grades. He speaks without contractions, perhaps because of his studious background or because English is his second language.

During the group's activities, he is often paired with Buford. While Buford often bullies him by taking his underpants, there is also a protective nature between the two of them. He also learns things he never knew he could do.

Phineas Flynn
Baljeet is often seen coming to Phineas for help or advice, which in turn gives Phineas the inspiration for their big idea of the day ("Unfair Science Fair Redux (Another Story)", "Attack of the 50 Foot Sister", "That Sinking Feeling", "The Baljeatles"). Phineas is always willing to lend a helping hand, and Baljeet is almost always included in the boys daily activities. On occasion, Phineas has come to Baljeet for advice, usually on trivial matters ("Tip of the Day", "Undercover Carl").

Ferb Fletcher
Because of Ferb's lack of speech, he is rarely ever seen directly communicating with Baljeet, and not much is known of their relationship, but it is assumed that they are also close friends as Ferb is always seen working with Phineas when helping Baljeet ("Unfair Science Fair", "Attack of the 50 Foot Sister", "That Sinking Feeling"). Baljeet appears to greatly admire Ferb's abilities and once stated to Phineas "Can I borrow Ferb sometime?" ("Attack of the 50 Foot Sister").

Candace Flynn
Because Candace doesn't want to ruin her reputation by being seen with her brother's friends, she rarely converses with Baljeet, but on a rare occasion was seen speaking to him at a seminar ("The Secret of Success"). For the most part she tends to ignore Baljeet because she is focused on busting her brothers. However, Baljeet seems to pay more attention to Candace, stating to Phineas that she had missed the song I Believe We Can before they took off on their journey together around the world ("Phineas and Ferb Summer Belongs to You!"). On one instance, when trying to show her mother the boys' haunted house, Candace keeps referring to the "ugly, hideous thing in their backyard", but because the house keeps being moved before her mother sees it, her mother believes that she is talking about Baljeet ("One Good Scare Ought to Do It!").

Isabella Garcia-Shapiro
Baljeet might have a crush on Isabella when Phineas and Ferb require two people to play a couple on a date so they can reverse engineer a machine. Baljeet says it was fate that he and Isabella were picked. Isabella, however, says Baljeet "charged to the dinner table like a crazed bull" ("What Do It Do?"). Baljeet has hinted also by saying "Was I a convincing Phineas?", implying he wanted to know how she felt about it. She replies with, "No, no you weren't" ("Not Phineas and Ferb"). In "Ask a Foolish Question", when he was viewing a computer showing random images during Buildin' a Supercomputer, he seemed to be annoyed when it suddenly showed Isabella thinking about Phineas. This may suggest that Baljeet is somewhat jealous about the relationship that Phineas and Isabella have.

Buford Van Stomm
Even though Buford is the local bully who always terrorizes Baljeet, they are often seen together, especially when they are involved in Phineas' and Ferb's Big Ideas. They seem to have formed a like-hate relationship and are often considered as frienemies. Though Buford uses Baljeet as a punching bag, he also confides in Baljeet some of his secrets, like that he can speak fluent French ("Phineas and Ferb Summer Belongs to You!"). Like a good frienemy, Baljeet doesn't mention this to the others, or perhaps Buford has intimidated him not to do so. Also, when Baljeet becomes stuck in a tree, Buford tries to entice him to come down with Baljeet's calculator and favorite math problems, and is seen overwhelmingly happy when Baljeet is saved ("The Beak").

Mishti Patel
Baljeet's childhood friend from India, who is seen to have been a close friend and playmate. She visits him four years later and Baljeet is shocked to discover she has "turned into a girl" as she used to be a tomboy. It is implied the two like each other, though Mishti seems to prefer a friendly relationship compared to Baljeet's attempts at romance, figuring that is what girls like. It seems that Baljeet has a little crush on her ("That Sinking Feeling").

Ginger
Baljeet does not know about this yet, but Ginger has a crush on him similar to Isabella's crush on Phineas ("Isabella and the Temple of Sap").

Wendy Stinglehopper
Baljeet seems to be friends with Wendy Stinglehopper, as they know each others' names and they both like math. Baljeet may even have a crush on her, because he risked his life to save her present. After, she and Baljeet notice the mistletoe above them, she kisses him gently. He acted shy, and then kisses her very passionately. He leaves her surprised and says "Later", definitely confirming that Baljeet likes her. ("Phineas and Ferb Christmas Vacation!")

Trivia

 * Baljeet's last name has not yet been revealed in any episode or any press release. It was thought to be "Patel", based on the original Wikipedia entry,and it is also given as such in Freeze Frame and the Phineas and Ferb Top Trumps Card Game, but an announcement by his mother ("Baljeet, the Patels are here") cast doubt on Patel being the correct last name. ("That Sinking Feeling") Jeff "Swampy" Marsh gave Baljeet a last name of "Rai" in June 2010, but later retracted it in October of that same year. For the moment, his name is just "Baljeet".
 * His first appearance by production schedule was in a crowd scene in "S'Winter" and his first speaking role was in "Raging Bully."
 * Baljeet's name indicates that he is most likely from India's Punjab region. He has immigrated to America (revealed in "Get That Bigfoot Outa My Face!"), although clues like him studying during summer vacation suggest he is either an immigrant or a foreign exchange student. Other clues are that in the song "Baliwood" from the episode "Unfair Science Fair", he states that his family stretches from the Himalayas to Kashmir (which are Indian locations).
 * When in danger, he always hyperventilates. ("Bubble Boys")
 * He is the only sixteenth-level Space Adventure trivia master on Earth. ("Nerds of a Feather")

 * In "The Baljeatles" he is afraid of getting an F at Summer Rocks, a Rock n' Roll camp he mistakes for a geology class.
 * In "The Baljeatles," because of his fear of getting an F, Baljeet didn't want to even pronounce the letter F, and calls Phineas and Ferb "Ineas" and "Erb".
 * He is the only boy to kiss a girl on camera. He kisses a Wendy Stinglehopper, a girl on the math team, after falling through her chimney with her present in the episode "Phineas and Ferb Christmas Vacation!"
