Asgore in Undertale Yellow, as compared to Undertale, is noticeably more grim about the situation of the monsters entrapment. Perhaps this is because, unlike Undertale, there is no certainty that another human will fall into the Underground. When learning Chujin's story, we see a side of Asgore that is colder. Instead of the benevolent ruler offering tea and conversation to anyone who enters his castle, we see a king who's reaching the end of his patience. Because of this attitude during the time, Ceroba quite vocally dislikes Asgore.
