The Great Sea Dragon is a female dragon only mentioned in the story of the discovery of the Dragon Realms in Spyro: Shadow Legacy.

In legend, she swam to the Realms from an ancient homeland with her babies on her back. Exhausted from her swim, the Great Sea Dragon passed away on the shore, right where the Dragon Shores' fountain stands. She wore the fountain's talisman around her neck; the magic from this talisman powers the fountain's jets.
