"The Balrogs originated as Maiar, beings of the same kind as Sauron himself. They were primordial spirits of fire that had allied themselves with Melkor in ancient times" - (с) encyclopedia of Аrda (лень в другом месте искать))
они не стали балрогами, они ими и были. просто стали служить Мелькору
"For of the Maiar many were drawn to his splendour in the days of his greatness, and remained in that allegiance down into his darkness; and others he corrupted afterwards to his service with lies and treacherous gifts. Dreadful among these spirits were the Valaraukar, the scourges of fire that in Middle-earth were called the Balrogs, demons of terror.
Among those of his servants that have names the greatest was that spirit whom the Eldar called Sauron, or Gorthaur the Cruel. In his beginning he was of the Maiar of Aulл, and he remained mighty in the lore of that people."
Сильма.
