Bub was a violent and short-tempered Anharrans Demon. When Xander and Dawn started helping the people of Anharra to build houses, Bub attacked Rancidus for not making him a bay window. Xander intervened and Bub claimed his response was due to cultural reasons. Xander found that Bub was secretly insecure and had a heart-to-heart with him. To boost Bub's self-esteem, Xander had everyone around them to give a round of applause. Bub later accompanied Xander, Dawn and Rancidus through the various dimensions in search of Earth. Bub ended up staying at Bodaceia to help repopulate.
