Dipper

16 years old and in Gravity Falls High School in Oregon. Dipper wears a dark moderate blue and white baseball cap with a dark moderate blue brim and a dark moderate blue pine tree on the front. He has somewhat messy brown hair and relatively pale skin, and his nose is a bit darker than the rest of his face. His eyes are brown, like Mabel's, with noticeable bags underneath. He wears a navy blue jacket (which has inner pockets on both sides), a reddish-orange t-shirt, gray pants, white knee-high socks with a red stripe, black sneakers with white soles, and a sometimes visible gray digital wristwatch. He is sometimes seen with a green backpack. He has a birthmark on his forehead shaped like the constellation, the Big Dipper, hence his nickname "Dipper", which he hides under his bangs. He also has Bill cypher and zodiac related tattoos on his left forearm.

Dipper is intelligent, compassionate, self-conscious, and rational, and sometimes, overly judgmental, and can't wait to grow up. An adventurer at heart, Dipper can't sit still and is always looking for the next riddle or mystery to solve. His scrupulous attention to detail is useful when he is attempting to solve mysteries, but sometimes his over-zealousness can leave others questioning his credibility. Dipper is shown to be extremely "genre-savvy", knowing that in most movies, nobody has a camera when they see the monster, or that the camera malfunctions, he brings along 17 cameras with him to take a photo of the Gobblewonker. He is wise and intelligent beyond his years, and his refusal to sit still when there are puzzles to be solved often leaves him restless in everyday situations. In "Carpet Diem", he has a habit of clicking his pen repeatedly when in deep thought. He seems to believe that he is often too busy with other work to bother with certain tasks, such as washing his clothes. He also seems to get very irritated when people think he's "cute" or "adorable", as he wants to be taken seriously as a grown-up from people around him because at most times, Dipper is more mature than others. He began glaring at his twin sister Mabel when she commented that he "sneezed like a kitten" in the episode "Headhunters".[15] When Dipper and Mabel (and Soos at times) are on their adventures, Dipper is the one to act as the leader mostly because he is shown to be very brave and smart. He is somewhat protective of his sister:[9] whenever she is in danger, he is always there to help and will do anything to get her free. He can sometimes be selfish and is not above using Gravity Falls' mysterious elements to his advantage. He can also be ruthless in the pursuit of his goals, such as not apologizing for attacking Soos in "Not What He Seems", unlike Mabel who apologized prior to grappling him. But ultimately, he always does the right thing and has the right motivations. It is also well mentioned that Dipper is paranoid and has had trust issues since the beginning when the journal warned him to "Trust No One" and has been skeptical about people and situations. For example, in "The Last Mabelcorn", Dipper fearfully backs away from Stanford Pines, who he thought was being possessed, while holding a memory gun pointed at his head, muttering the phrase "Trust no one" repeatedly to himself. With his experience in Gravity Falls as well as his knowledge in the mystery novels that he reads, Dipper thinks much like an actual detective, as seen in "Headhunters". Despite his brave and serious personality, living with Mabel Pines his whole life (who is famous for her silly and fun-loving attitude) has caused him to indulge in childish activities with her, such as when both he and Mabel made puking noises whilst spraying silly string onto each other's faces in "Double Dipper". At the beginning of the episode "Headhunters", he and Mabel are seen watching Duck-tective. When a video was displayed in the future detailing the twins' current positions in "Blendin's Game", it showed Dipper and Mabel hitting each other with soft bats while laughing. Whilst playing miniature golf in "Carpet Diem", Mabel states that his shot is out of bounds, to which he responds by poking her with the golf club and shouting "YOU'RE out of bounds!", ending up with both twins poking each other. In the episode "Not What He Seems", Dipper and Mabel play with water balloons, enjoying classic summer fun.

He also seems to not mind breaking the law to have fun. For example, in "The Stanchurian Candidate", when Stanley Pines asks Dipper and Mabel if they want to vandalize the new mayor's house, they both follow their uncle while cheering for joy, and Dipper even yells "Yay! Vandalism!". In "Not What He Seems" Stanley, Mabel, and Dipper are seen on the roof of the Mystery Shack bonding by exploding fireworks. When asked by the police if they have a permit, Stanley responds with "Do you have a permit for being lame?" to which they all laugh. In a "Fixin' it with Soos" episode, Soos tells Dipper and Wendy to hit the nitrous boosters that he installed onto the golf cart. Dipper asks "Aren't those illegal?", and Soos responds with "You bet your life they are baby!" All three of them then laugh with joy as the golf cart drastically speeds up.
