A haughty, greedy alien queen looking to conquer Earth. Unbeknownst to Xartha, human food has an addictive effect on her; the more she eats here, the fatter and more gluttonous she becomes. As she gains weight, she loses self-control and self-awareness, burping, eating messily, and even farting openly. If drunk, she will also become cruder and enjoy burping and farting at, and flirting with, people for fun. Eventually, Xartha will become a mindlessly gluttonous, gassy, obese blob of a woman.
