|After becoming the sole security guard of Greendale Community College, Sgt. Ben Chang needed more personnel to assist him. He recruited a group of kids to form his security force. They are given the nickname "The Changlourious Basterds" after the Quentin Tarantino movie "Inglourious Basterds". Under Chang's leadership, they soon establish themselves as a force to be reckoned with. They first appear in the Season Three episode "Contemporary Impressionists".|
|In the study groups third year at Greendale, Dean Pelton admonished his head of campus security at the time Ben Chang for his overzealous actions involving the use of a tranquilizer gun. Chang declared he had to resort to extreme measures because he was all by himself. Pelton told him to recruit volunteers from the student body. However, despite his best efforts at recruitment, nobody at school is interested. Chang's brother later arranged for him to provide security for a Bar Mitzvah. He easily impressed the children attending the party and decided to recruit them instead for his security team. Chang brought them back to school where he addressed his new troops in the cafeteria ("Contemporary Impressionists"). They would later participate in The Pillows and Blankets War and become collectively known as the "Changlourious Basterds" .
|The struggle between Troy's Blanketsburg group and Abed's Pillowtown group, Troy asked for Chang and his recruits to lend assistance to his efforts. He did this in response to a WMD he learned Abed was about to unleash. They become a terrifying threat on the battlefield, raiding Pillow Town and maliciously attacking its residents. They even start collecting mattress tags as trophies and wearing them as necklaces as reminders of their "kills." However, they were stymied when they encountered Abed's weapon which was codenamed "Pillow Man". Overwhelmed by its power, they retreated but later got their revenge in a final showdown between the forts on the cafeteria. The Basterds used teamwork and took out their hated rival with extreme force ("Pillows and Blankets").
|Chang began demanding more authoritative power from Dean Pelton but was at first refused. Pelton changed his mind after an incident occurred in the cafeteria during Star-Burns memorial service . The students attending the event started to riot due to the study group's inflammatory anti-Greendale rhetoric. Chang then got Pelton to allow extreme measures to be taken to contain the situation. The Changlourious Basterds were mobilized, equipped with riot gear and headed toward the cafeteria. However, instead of calming the situation down, they made things much worse. They assaulted the students with pepper spray and exacerbated the riot they were called in to stop. Afterwards, the Greendale school board demanded to know who was responsible.
At an impromptu hearing, the study group attempted to pin the blame on Chang and the Changlourious Basterds. It proved futile because Chang had already ingratiated himself to the board. On top of that, Chang kidnapped and replaced their only ally Dean Pelton with a look-a-like called Faux-by. He impersonated the Dean at the hearing and told the school board to expel them. The board did just that which left Chang and his security force in complete control of Greendale ("Course Listing Unavailable"). Two months passed as Chang and his security force ruled the campus unopposed. Chang was in Dean Pelton's office when he received a call from an underling who told him that the study group knew Chang kidnapped the Dean. Chang proposed to his men that they move to phase two of the plan. When asked by one of his stooges what that is, he admits he has no idea and asks them all for advice.
It is then that one of the Basterds, Megan, offers him a cocktail which he happily accepts. Later in the episode "First Chang Dynasty", Chang is throwing an elaborate birthday party for himself at the Greendale campus. Having a suspicion that the Greendale Seven are up to something, he tightens security but is unaware that Troy was able to get a rundown of those plans from his inside connection Murray at Greendale.
