Bulgaria: Stoyan Georgiev
Croatia*: Silvijo Blažević
Greece: Heracles Karavitis (semi-canon)
Romania: Viorel Popescu
Serbia*: Blagoje Petrović
*Technically speaking, Croatia and Serbia have appeared in the series one time each. It was never specified it was Croatia, but was heavily implied to be so. Serbia was just a head. I decided to go ahead and include them.
