In Family Guy, Cleveland Brown was a regular character who served as a friend of Peter Griffin. However, when The Cleveland Show was created in 2009, the character was given his own spin-off, and Cleveland, along with his family, was written out of Family Guy. The decision was largely driven by Seth MacFarlane’s desire to explore Cleveland’s backstory and family dynamics in a new show. After the spin-off was canceled, Cleveland made his return to Family Guy in season 12, where it was explained that he moved back to Quahog after his show ended. This shift allowed Cleveland to resume his friendship with Peter, Quagmire, and Joe, while the continuity between both shows was kept intact in a playful and self-aware manner.
