Katarina was the sponsor of and announcer at the Ghostbusters' discussion on ghostbusting at a conference in the Soviet Union. Once they checked in with her, Katarina showed them their rooms, the institute's collection of paranormal artifacts, and a laboratory. She was convinced to help the Ghostbusters after Vladimir Pavel Maximov and Dmitri Smerdyakov blamed them for stealing "The Nameless Book" so that they could summon The Old One. After the Old one was defeated and Vladimir and Dmitri arrested, she gave a kiss to all of the Ghostbusters, including Slimer.
- Katarina's Patronymic name, "Ivanova," was used again by writer J. Michael Straczynski for his Babylon 5 character, Susan Ivanova
