Ivan Brother Theory
Despite being of a completely different nationality and being far to young to be birthed by Ivan's dead mother, Many believe that Ivan and Kata are siblings. This is purely based off of a similar appearance and similar aura of raw SEX.
Widowmaker Theory
It is believed that Blizzard used Kata's unique brand of French SEX as an inspiration for their popular character, Widowmaker. The validity of these claims are untested but for many they both give off a similar aura of SEX and are both of french descent, not to mention both wear diapers.
