Here are some examples of characters who left the show under circumstances that could be interpreted as being "kicked off":
* Puck (Mark Salling): His character left the show in season 4 due to the actor's real-life legal issues. While not explicitly stated as being "kicked off," it was a situation that led to his departure.
* Santana (Naya Rivera): While Santana's departure was planned as a storyline, she was initially written off due to the actress's desire to pursue other projects.
* Brittany (Heather Morris): Her departure was also part of a storyline and tied to Santana's departure.
However, it's important to note that many actors left Glee for more typical reasons, like focusing on other opportunities, pursuing different projects, or simply ending their time with the show as their characters' storylines reached their conclusion.
Ultimately, the show's creators and writers made decisions about character departures based on a variety of factors, and it's difficult to label any specific character's departure as being "kicked off" in the traditional sense.
