Zmey Gorynych

In Slavic Mythology, Zmey Gorynych was a monsterous dragon. The creature is sometimes thought of as a Hydra because of its three heads. Russian fairy tales often describe fire dragon Zmey Gorynych as "a villain who much evil has done. He has overrun all the neighboring realms, laid them waste and taken people captive."
