Mabel Pines is the female protagonist of the Gravity Falls series. Mabel is an energetic 12-year-old girl (she and her brother turn 13 at the end of the series finale; later 15 in Forever Sophomores) who is sent with her brother to spend her summer vacation in her great-uncle's tourist trap called the "Mystery Shack". She helps her brother Dipper as he endeavors to uncover the secrets of the fictional town of Gravity Falls and to find an explanation for the strange situations he experiences.
Mabel Pines is an energetic, optimistic and bouncy girl from Piedmont, California, forced to spend her summer together with her great uncle Stan in the fictional town of Gravity Falls, Oregon.She is accompanied by her twin brother Dipper Pines. Their parents aren't revealed in the show. She makes the best of every situation with a big, goofy smile and her variety of colorful sweaters and skirts. She is a self-proclaimed arts and crafts master, going so far as to make a wax figure of her uncle Stan with the leftover wax of a melted figure during the episode "Headhunters". She is actually growing to like Grunkle Stan and he likes her too, and is often protective. Mabel is boy-crazy and dislikes anyone who opposes her brother. She has a pet pig named Waddles who she won in the episode "The Time Traveler's Pig". Despite seeming as just being there for comic relief, Mabel is frequently instrumental in helping her brother solve the mysteries of Gravity Falls and played a pivotal role in all three of the fights that the twins have had against the main antagonist, Bill Cipher, to the point that Dipper says that he has no chance of defeating Bill without Mabel's help.
Off to the Falls Edit
1 Year after the Gravity Falls series ended, Dipper and Mabel meet Phineas and Ferb after Ford takes them to Danville, so he can use their brains to help rescue his brother Stan, who was kidnapped by Caillou. Because their parents are on a trip to Hawaii around the same time, they stay with the Pines twins. As more of their closest friends move in, the gang does many things, such as going to a Murder Mystery play, a Lego Convention, a couple Baseball Games, etc. Eventually, they have a final battle with Caillou and Bill Cipher before parting ways.
2 Years Prior to Forever Sophomores Edit
Not much is known what Dipper and the gang have been up to during the 2-Year Timeskip, except for the fact that Him and Mabel are now Sophomores, sent Waddles to live with their father, and the twins' mother is still with her verbally-abusive boyfriend Dan.
Forever Sophomores Edit
2 Years after "Off to the Falls", Dipper and Mabel begin to recall the adventures they had with Phineas and Ferb, and eventually decide to give them a call. They plan to meet up at the Mystery Shack the next day. The Reunion changes from happiness to rage when Caillou joins the party uninvited. Despite his attempts to apologize and warnings about Bill, Mabel, along with the others, are still mad at him and shut him out. Caillou finally earns their trust by performing CPR on Perry after he was knocked out during a battle with Bill and Tord. since then, Phineas and the gang begin to constantly hang out with Caillou and do many fun things together.
Mabel is a short 15 year old girl, exactly one millimeter taller than Dipper. She has fair skin, brown eyes, pink blush spots on her cheeks, and long brown hair that reaches to her hips. He also has silver braces. Her outfit changes a lot in Gravity Falls, more often than other character. She often wears turtleneck sweaters of varying colors(usually, pink, green, light blue, yellow, red, purple, or other colors) with different symbol on it, along with a matching skirt(sometimes jeans or leggings) and headband. However, her signature, and most common outfit consists of a pink t-shirt underneath a fuchsia pink turtleneck sweater with a shooting star on it, a matching fuchsia headband, a purple mini-skirt, long white socks, and black ballet flats.
