Gergoth

Gergoth is a boss monster first appearing in Castlevania: Dawn of Sorrow. In the English localizations, he is described as supposedly being a once gentle beast who grew deformed and was driven mad by imprisonment. The reason for his imprisonment is yet unknown. In the Japanese versions, however, Gergoth's description says he was once a criminal imprisoned in ancient times, who grew deformed and twisted by cursing all of creation.
