Gibbay appointed director of new ICarly movie!

Orenthal Cornelius "Gibby" Gibson (Noah Munck) is a friend and classmate of Carly, Sam, and Freddie and the show's breakout character. Due to his odd personality and chubby appearance, he is an outcast at school, although he does have a few friends. He used to be known for taking off his shirt in almost all episodes he appeared in. Since season 4, he has not taken his shirt off and stated in "iStill Psycho" that he takes it off "less frequently now". He often appears on iCarly to assist Carly, Sam, and Freddie. Gibby started off as an occasional recurring character of the show, but was promoted to a main character by season 4. Gibby has a little brother named Guppy, played by Munck's younger brother. In "iMove Out", he has a pet bulldog named Grubbles. Gibby also has a pet cat which he apparently likes to film, mentioned by his girlfriend Tasha in "iEnrage Gibby". A running gag in many episodes usually has many characters yelling "Gibby!" to him, either when they are aggravated or annoyed by him. Since becoming a series regular, Gibby often announces his presence upon entering a room with his own name deepened voice: "Gibbeh!" It was revealed in the episode, "iStill Psycho", that his birth name is Orenthal Gibson.

Much like Freddie, he is often a victim of Sam's pranks, but she has shown to have more respect for him. In "iSpeed Date", his last name is revealed as Gibson on his house's postbox, which read "The Gibsons". The episode also reveals he has a girlfriend named Tasha. A very attractive girl, she only has a small part in the episode. This surprised Carly, Sam, and Freddie, because they feel that Tasha is somewhat out of Gibby's league. In "iEnrage Gibby", Tasha returns and has a larger role, showing much affection towards Gibby. In this episode, Gibby is shown to be ruthless and jealous, but in a comedic way. He is also shown to be a skilled kickboxer. Gibby is portrayed to be a very capable fighter, almost to the level of Sam, as shown in "iPsycho", where he succeeds in smashing down a barricaded door. In the episode "iCan't Take It", Gibby is shown to be a strong singer when he serenades Sam and Freddie after he has a change of heart about trying to break them up. He also reveals in "iMeet the First Lady" that he thought Spencer was Carly's father. He says this again in "iGoodbye".

His mother's name is Charlotte. His parents are divorced. He also has some emotional problems because he is the main target for most bullies (mostly Sam in the first three seasons).
