Chang may be evil, but he's also really, really stupid, and the Community universe rarely misses an opportunity to reign misery upon him for it. The first season saw him lose his job, the only thing he had that adhered to his false sense of superiority. Season two focused with something close to sympathy on the pathetic mess of a life left him at the end of Season one. Season three brings us the return of evil, cartoony Chang as he takes a campus security guard position and gets into all kind of crazy sitcom hijinks.
What will come of Chang's future - if he or anyone else on that show are granted a future - remains to be seen, but it's doubtful he's going to grow a big brain in the meantime.
