Dobrynya Nikitich and Zmey Gorynych (dragon).
The bylina begins with Dobrynya's mother telling the hero not to go to the Saracen Mountains, not to trample baby dragons, not to rescue Russian captives, and not to bathe in the Puchai River. Dobrynya disobeys his mother and does all of these things.
When he is bathing in the Puchai River, the dragon appears. Dobrynya has nothing to defend himself, and thinks he is going to die. Dobrynya then discovers "a hat of the Greek land" and uses it to defeat the dragon.
The dragon pleas for Dobrynya not to kill him and the two make a nonaggression pact. Once the pact is made, the dragon flies away and captures the niece of Prince Volodymir, Zabava Putyatishna.
When Dobrynya arrives at Kiev, Prince Vladimir tells Dobrynya to rescue his niece. Dobrynya makes it to the Saracen Mountains with the help of a magic whip given to him by his mother, and begins to fight the dragon.
Dobrynya fought the dragon for three days. On the third day of the bloody battle, Dobrynya feels like giving up and riding away, but a voice from heaven tells him to stay and fight for three more hours. After the three hours Dobrynya kills the dragon.
When he killed the dragon, the blood did not soak into the ground, and Dobrynya and his horse were stuck in the blood for three days. A voice from heaven told the hero to stick his spear into the ground and say an incantation. The blood was then swallowed by the earth and Dobrynya rescued Zabava.
Since Dobrynya is a peasant, he cannot marry Zabava and gives her to Alyosha Popovich. Dobrynya encounters a polyanitsa, Nastasia, and marries her instead.
Zmey Gorynych - is the Slavic dragon
In Slavic mythology, the word zmey or Змей and its cognates zmiy, zmaj, zmej and ?mij are used to describe a dragon. Most of these words are masculine forms of the Slavic word for "snake", which is normally feminine (like Russian zmeya). In Romania, there is a similar figure, derived from the Slavic dragon and named zmeu. In Polish and Belarusian folklore a dragon is also called smok. Although quite similar to other European dragons, Slavic dragons have their peculiarities.
In Ukraine and Russia, a particular dragon-like creature, Zmey Gorynych or Змей Горыныч, has three heads, is green, walks on two back paws, has small front paws, and spits fire. According to one bylina, Zmey Gorynych was killed by Dobrynya Nikitich.
Other Russian dragons (such as Tugarin Zmeyevich) have Turkic names, probably symbolizing the Mongols and other steppe peoples. Accordingly, St George (symbolizing Christianity) killing the Dragon (symbolizing Satan) is represented on the coat of arms of Moscow. Some prehistoric structures, notably the Serpent's Wall near Kiev, have been associated with dragons as symbols of foreign peoples.
Russian dragons usually have heads in multiples of three. Some have heads that grow back if every single head isn't cut off.
