Shannon Beiste is the new football coach at William McKinley High School who replaced Ken Tanaka.

Shannon appears to be a very intense and driven woman, who wants to do whatever she can to train her players into being a formidable football team. However, she has also shown to be very sensitive because of being bullied as a child due to her large size, deep voice, and somewhat masculine appearance. This sensitivity causes her to become petty and easily angered, which she then takes out on those who end up in her line of sight. But it appears that she is not a cruel woman, like Sue is (or at least not as cruel), but instead just wants to be accepted and appreciated. She has French heritage, as mentioned when she spells out her name. She also seems to enjoy music quite a bit, as she can be seen singing along to "Need You Now" and "TiK ToK".
