Doc Brown

Dr. Emmett Lathrop "Doc" Brown is A scientist by trade, Doc was a "student of all sciences" who spent much of his time inventing. Doc is a highly brilliant, quirky scientist who is passionate about science but is quite crazy, almost to be a point of being pretty nuts, as he has taken part in actually stealing plutonium, and having terrorists come after him. Despite his quirkiness, Doc does care about those he's close to. He's kind-hearted, supportive, encouraging, and plays as a positive mentor to Marty, to a point of actually being quite paternal. Though Doc is incredibly clever and inventive, he could be absent-minded at times and was regarded by many of Hill Valley's townsfolk as abnormal or as a nutty mad scientist. As a scientist and a time traveler, he takes his job very seriously. Doc often worked through the night on his inventions and could become obsessed with little things. He would always try to use a big word rather than a small one if one is available – for example, he referred to a dance as a "rhythmic ceremonial ritual". He also has a rather archaic and Shakespearian way of speaking, as he repeatedly uses phrases and words that are somewhat outdated to be even typical of the 20th century. He could also be a showoff with his knowledge, as when he saw a dinosaur tooth and identified it as a "third incisor from the apex of the dental bridge". Doc often used the phrase "Great Scott!" as an exclamation. He also liked jazz music, Jules Verne novels, and Westerns. Green was his favorite color, one that he found soothing. Although he had a perchance to gamble, he would never use time travel for that reason. Doc did not usually drink alcoholic beverages since he had a tendency to pass out after just one drink, especially when that drink was whiskey. He was allergic to all synthetic fabrics. Doc sometimes went to great lengths, even illegal acts, that would allow him to complete his projects. Although he was usually careful about being discreet with the DeLorean, he referred to the time machine as a time machine in public, leading Biff Tannen to use it without Doc's knowledge in an attempt to alter history. The DeLorean time machine was Dr. Emmett Brown's most successful invention, a plutonium-powered time machine built on a DeLorean DMC-12 sports car that had to reach 88 miles per hour in order to time travel. On November 5, 1955, Doc was standing on the edge of his toilet, while hanging a clock in his bathroom. The porcelain was wet, making Doc slip, fall and hit his head on the sink. When Doc came to, he had a vision of the flux capacitor in his head, and drew a crude schematic diagram as well as scrawling some hurried calculations. The capacitor was constructed afterward and completed in 1985. The actual construction of the components for the finished machine took Doc 30 years and most of his family fortune to complete.
