This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Garuda (Hindu)
Garuda who is primarily depicted as the mount (vahana) of the Hindu god Vishnu. This divine creature is mentioned in the Hindu, Buddhist and Jain faiths. Garuda is also the half-brother of the Devas, Gandharvas, Daityas, Danavas, N?gas, Vanara and Yakshas. He is the son of the sage Kashyapa and Vinata. He is the younger brother of Aruna, the charioteer of the Sun.
Garuda is described as the king of the birds and a kite-like figure. He is shown either in a zoomorphic form (a giant bird with partially open wings) or an anthropomorphic form (a man with wings and some ornithic features). Garuda is generally portrayed as a protector with the power to swiftly travel anywhere, ever vigilant and an enemy of every serpent. He is also known as Tarkshya and Vainateya.
