Balačko

Balačko is 3-headed giant from Serbian folklore. From one head he could spit fire, from second one he could breathe cold wind. When he depleted his magical weapons, he was easy to kill. He was under the rule of Mihailo the king of Leđane. He was killed by the serbian hero Miloš Vojinović when he tried to kidnap princess Roksanda, the bride of Tsar Dušan. This tale was told in the serbian epic poem "Tsar Dušan's wedding" (Женидба Душанова). He was refered to as a Voivode.

"Sir, serbian Tsar-Stjepan,

here in the city of Leđane,

there is one, Voivode Balačko,

I know him and he knows me;

the king fed him for seven years

so he can disperse the wedding guests

and steal lady Roksanda;

now he is going to send him after us.

On Balačko there are three heads:

from one blue flame beats,

and from the other cold wind blows;

when the two winds leave his head,

Balačko is easy to kill;

so you go on, lead your lady,

I am going to wait for Balačko,

so I can somehow stop him."
