- In the comics, Ivan Petrovich Bezukhov was Natasha Romanoff's foster father and mentor.
- In Captain America: The Winter Soldier, Arnim Zola identified Natasha Romanoff as "Romanoff, Natalia Alianovna". However, according to Russian naming convention, her middle name is invariably a patronymic, and based on that her father's name must be Alian.
