History
Raissa was the little daughter of Sergei Ivanovich, a KGB agent who wanted to defect to the United States. Knowing many secrets of Soviet espionage, it was decided to eliminate it by using their best assassin, the Winter Soldier. While trying to hit Ivanovich with a sniper shot, he missed when he saw Ivanovich's little daughter appear and only managed to wound him, so he went in pursuit and when he reached him he didn't want the little girl to see that he was killing her father and handed her over to the Black Widow, who had secretly followed the Winter Soldier, so that he would not see and at that point killed Ivanovich by stabbing him to death, while Natasha embraced Raissa not letting her see the murder.[1]
