Troy and Abed are best friends whose bromance has been prominently featured on the show. The other members of the study group are both amused and disturbed at how close the two are. Their many misadventures at Greendale inevitably drag their friends (and sometimes the entire school as well) into the hijinks. Because Abed is unable to adequately express emotion, and Troy is overly emotional, this has lead to a few conflicts between them. They soon make up, however, as they understand they are better together than apart. Troy is played by Donald Glover, and Abed is played by Danny Pudi.
–Abed and Troy demonstrating their Spanish 101 oral assignment
in thier first year at Greendale, Abed invited Troy along with other classmates from Spanish 101 to Jeff's study group. Even though Troy found him to be odd at first, they eventually began to hang out more. They partnered up on school assignments together including a Spanish project and a science experiment with a lab rat. They soon formed a friendship that only got stronger throughout the year until it blossomed into a full blown bromance. Troy even conceded that Abed was the better athlete and referred to him as his "other half". Their relationship prompted Annie to get over her crush on Troy since she couldn't compete with Abed for his affections. When Abed decided to do a college cliché bucket list, Troy eagerly assisted him. The pair tried to join a campus fraternity, built a robot, got into a huge food fight in the cafeteria and teamed up for a Paintball Assassin game. At the end of the school year, Troy needed a place to stay after he was told by his father to move out. Troy asked Abed if he could move into his dorm room but was refused. Eventually Troy came to understand Abed's reluctance realizing spending too much time together at that point in their relationship could ruin their friendship. Taking Abed's advice, Troy instead accepted Pierce's offer to move into Hawthorne Manor.
In thier second year together at Greendale, Troy was living with Pierce at his mansion. His friendship with Abed still remained strong as the duo had a number of misadventures on campus. This included facing off against a horde of students affected by a zombie-like contagion and building their first blanket fort. Before the Winter break, Abed had a mental breakdown and Troy, alongside the study group, helped him resolve his personal issues in a therapy session with Ian Duncan. During thier Spring semester, they competed for the affections of the school librarian. She ended up choosing Troy who in turn rejected her after she said disparaging things about Abed. The pair also became good friends with a foriegn student named Lukka who briefly hooked up with Britta. They made some quick cash by selling their handshake to Pierce but ended up regretting it. At the end of the end of the school year Troy and Abed participated in the annual pantball assassination competition. When City College invaders interjected themselves into the game, Troy and Abed rallied the remaining Greendale students to put in end to their plans.

–Troy, "Curriculum Unavailable"
In their third year at Greendale, Troy and Abed finally moved in together. Eventually they asked Annie to join then as their roommate which she happily accepted. Each face their own individual challenges during the 2012-2013 semester; Troy is tempted to join an elite secret society while Abed started to lose touch with reality inside his new playroom. Troy confronts Abed on his issues, particularly an unsettled debt he owed to a celebrity look-a-like company. At the same time Abed is uneasy after he noticed Troy and Britta's growing attraction to each another. Their friendship was further tested when they had a serious falling out over the construction of a pillow fort. Although it was peacefully resolved, Troy and Abed's problems continued as the study group was blamed for a riot in the cafeteria. Thanks to Chang manipulating the school board the study group is expelled. Ultimately the study group clears thier name and are reinstated but at a cost; Troy is forced to join the air conditioning school and cut off all ties to Abed and his friends. The loss of his best friends sends Abed into a deep depression.
The duo entered their fourth year at Greendale with Troy in a relationship with Britta and Abed worried about the study group breaking up after Jeff graduated. Troy attempted to alleviate his best friend's anxieties about the future and also tried to make him comfortable with the fact he was now dating. Towards the end of the school year, Abed did the same thing for Troy by helping him deal with an issue he had been struggling with but trying desperately to avoid.
Sometime after graduating, Troy and Abed along with the other study group members decided to reenroll at Greendale after Jeff accepted a position there as a teacher. One of the first classes they took was a course on movie star Nicolas Cage taught by Professor Garrity. Troy worried when Abed becomes obsessed with the actor and later witnessed him having a nervous breakdown in class. Along with their friends the duo joined a new group at school called the "Save Greendale Committee". Later, Troy was assaulted by the "Ass Crack Bandit" and Abed did his best to comfort his friend. They were both saddened when informed of Pierces death and later attended his funeral along with the rest of the study group. Pierce bequeathed Troy his shares of Hawthorne Wipes on the condition that he sail around the world before receiving it. Abed had trouble accepting his friend was leaving but tried to say goodbye through a campus wide game of "Hot Lava". After having one last adventure together, Troy said goodbye to Abed and the study group. He left the campus with co-captain LeVar Burton on a rig pulling the boat they will be sailing on, the "Childish Tycoon".
