Orange is a main character in all of the Annoying Orangeshorts, as well as the show's lead protagonist. He is portrayed by Dane Boedigheimer, the chief investment officer of Gagfilms. Orange has made full appearances in every episode since the start of the series on October 9, 2009, which is also his birthday. Orange has yellow teeth, grey eyes, and a braying laugh. Episodes are characterized by his taunting and annoying his victims-to-be with his adolescent behavior that frequently include burping, pestering, puns, and play-on-words. These actions often infuriate the other character to the point where they start yelling at him to "shut up", only to have Orange warn them of their impending catastrophe: evisceration with a chef's knife, a blender or other types of death like being squashed by some heavy items (like Liam the Leprechaun and Gecko) or eaten by animals such as Squirrel. He has a very famous quote, which comes after someone calls him something that he isn't: "No, I'm not. I'm an orange!". Boedigheimer describes the character as a composite of people in his life, saying "everyone knows somebody like him: They don't listen, they are annoying, and at the same time they are kind of lovable".
Orange is depicted as an exasperating anthropomorphic orange. He is the central character in the series, though not always the main character in some episodes.
Orange is disliked by many characters, because he constantly heckles them in many ways, such as spitting seeds, mistaking them for other things, and making childish noises. In the episode More Annoying Orange, another orange comes and actually annoys Orange which is in contrast to what it is originally. Not much is known about Orange's past; it was confirmed that he was actually born the day he debuted.
It is unknown why Orange gets such joy from annoying people, but one possibility is that any other orange is like that. Another possibility is that he just likes puns and jokes, and doesn't pay attention to how people are being annoyed, according to his friend Passion Fruit.
Orange is annoying, oppimistic, dim-witted, usually cheerful, and witty he also loves to crack annoying puns. He almost always blunders things for their color. For example, Orange thought Tomato was Apple because they were both of a red color, and he thought Pumpkin was a orange because he was of an orange color.
In reality, Orange is very kind and innocent at heart, because if he really likes somebody, he will try to think of something that will make them like him a little bit. As revealed in More Annoying Orange, Orange is actually considered very mild for his species, and he is considered the most annoying thing that most of the characters have ever met because they probably have never met an orange before. He probably just tells puns to make him feel better, as he has seen a lot of people get minced up, and gets upset when one of his best friends is knifed. His act of being dim-witted helps him get out of bad situations, as shown in Annoying Orange Saw. If he gets extremely offended or hates somebody, he will be purposely annoying. When he sees someone get killed (usually by evisceration from Knife), he will usually watch in horror and sometimes scream, but if the person is someone he loathes, he will laugh at their disbursement.
Sometimes it happens that Orange demonstrates his few learning by mistaking a fruit for another and continuing to say that a fruit is another like it happened to Pumpkin (Orange thought it was another tremendous orange). Orange's innocent and playful antics have garnered him both a lot of friends and rivals.
