Ludmilla Vobet is a very minor character in the Rocky series. Not a very good one in my opinion either.

She was the wife of Ivan Drago and she apparently was some kind of Olympic winning medalist in the Soviet Union too. She was very supportive of her husband. Until he lost against Rocky Balboa. In Creed II, we find out they divorced shortly after.

The only neat thing about her character was that she was played by Bridget Nielsen. She was actually married to Sylvester Stallone for a little while around the same time as Rocky IV.
