This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Daitya (Hindu)
In Hindu mythology, Daitya describes a member of a clan or race of giants, who were the half-brothers of the Devas (benevolent divine beings). The Daityas, who fought the Devas because they were jealous, are sometimes described as demons or giant evil spirits. The ancient Hindu legal text Manusmriti, on the other hand, describes the Daityas as basically good, but puts them at a level lower than the Devas.
The female Daityas are described as wearing jewelry the size of boulders. In the Manusmriti, the Daityas are still considered benevolent beings, but not in as elevated states as the Devas. In the beginning, the Daityas defeated the Devas with the help of Vritra, the dragon serpent. Once defeated, the Devas sought-out council from the powerful God Brahma, who informed them of how to defeat the Daityas.
