Leviathan

This is a long, thin snake-like dragon who controls the power of water. It looks similar to a Japanese dragon, which is usually assosciated with water rather than fire. In FF4 and FF5, this monster (not Bahamut) was the King of Phantom Beasts/Summons. In FF7, it was the personal god of Wutai and its scales could calm the fires in Da-Chao Statue.
