Gobi Nadir is first mentioned in passing by Abed in his first year at Greendale. He told Jeff his life story and described his father as possessing an "angry energy" that puts off people who meet him. Abed attributed that anger to his wife (and Abed's mother) leaving him and not anger at America, although she was American and Gubi was angry about that ("Pilot"). After Gobi learned that Abed has taken a film class because Britta gave him money, he goes to Greendale to confront her about it. He found Abed, Jeff, and Britta on the quad and demanded that she stop interfering in Abed's life. He then insisted to Abed that he drop the course immediately since he is only willing to pay for the classes related to running the falafel restaurant.
Now we have this between us!
Gobi and Britta get into an argument about Abed's future as she believed he should be able to follow his dreams. Gobi said that it was hard talking to Abed before, and now his interest in filmmaking created an additional barrier between them. He attempted to physically take his son away with him but Jeff intervened, separating him from Abed and Britta. Jeff made the point that Abed is an adult and should be allowed to make his own decisions. Frustrated at their interference, he declared that they can raise Abed and left. Over the next few days, Britta tried to do her best to look after Abed but is upset to find out how he's been spending his time and her money. He had been spending the money she lent him on luxuries like a brand new film camera and lunch for the study group. He has also become obsessed with finishing his film project, casting Britta and Jeff in the roles of his mother and father respectively.
You want to raise him, you raise him! I'm out!
On top of that, he's been skipping the very class she insisted he take. Jeff took it upon himself to try to resolve the matter by getting Gobi to return to campus under the pretense that Weezer was showing up in the study room. He also got Britta and Abed to show up as well; however, things between Gobi and Britta become heated again, and another argument breaks out. Abed, who had been working on a computer the entire time, interrupted and told everyone that he just finished his movie. He got the three of them to sit down and watch it. Although Britta and Jeff are confused by it, Gobi immediately understood the message behind the short film. Moved to tears, he told Abed that he never blamed him for what happened with his mother. Gobi admitted he was wrong and agreed to pay for the film class so that his son could express himself (" Introduction to Film").
Gobi appears later in the year with Abed's cousin Abra for the Family Day event at Greendale. In the Spanish classroom, he meets Shirley and her kids and introduces himself and Abed's cousin Abra. He is over protective of his brother's daughter and refuses to let her interact much with anyone. At one of the day's events, a BBQ is held outside on the quad and the Nadirs join Shirley and her kids for lunch. Abra asks her uncle if she could play with Elijah and Jordan in a bouncy house that had been set up but Gobi won't allow it, worried for her safety. They get into an angry argument in Arabic and she calls him a pig's anus. When Gobi leaves to change shirts after Elijah and Jordan accidentally spill a drink on it, the kids don her burqa in order to impersonate Abra so she can sneak away to play inside the bouncy house. The kids later distract Gobi to let her change back and he is none the wiser ("Basic Genealogy").
Abed mentions that his father is withholding ("Intro to Felt Surrogacy"). Gobi makes an appearance in several flashbacks to Abed's time before Greendale in 2008. It's shown that Abed harasses Shirley's children at the Greendale Mall when they try to go to the movie theater to see a reshowing of "The Phantom Menace". He gets a restraining order put on him, and Gobi forces his son to see a therapist for his actions. Later, he takes Abed back to the Greendale Mall and while eating yogurt at Yogurtsburgh, he tries to get Abed to apologize to the theater manager. Abed refuses due to his hatred of the film and Gobi tells him he won't allow him to go film school to pursue his dream of becoming a filmmaker ("Heroic Origins").

“Interesting. I didn't see any Iraq metaphor but...”— Jeff
“What Iraq metaphor? I'm talking about your speeches and her [gestures at Britta's chest] guided missiles!”— Gobi
