Claws Wiki

Riva (Russian: Рива, Riva/Georgian: რივა, Riva) is the former leader to the Russian Mafia and the sister to Zlata Ostrovsky. She is an antagonist in Season One and a minor character in Season Two of the series Claws, portrayed by Andrea Sooch.


From the little that is known about her, it is known that Riva comes from Eastern Europe (Russian, Georgian, ethnic Georgian in Russia or possibly ethnic Russian in Georgia) and spent some time in prison before going to the United States (mainly due to the tattoos she has on her hands, typical of criminals and members of the Russian Mafia).

Sometime before the events of the Season One, she migrated to the United States, where she settled, in Palmetto, Florida and where she established her own criminal organization, the powerful Russian Mafia.


Riva is shown to be a powerful and ruthless criminal, mainly due to her status as head of the Russian Mafia. She has a strong temperament, and often clashes against other powerful criminals, like Gregory Ruval (the head of the Haitian Mafia and Clay Husser (the head of Dixie Mafia).

Interestingly, it has a good relationship with Desna Simms and her group, the Desna's Divas, to the point of being a client of the Nail Artisan of Manatee County managed by Desna and having a business partnership with them.

On the other hand, Riva shows a deep hatred against her own sister, Zlata Ostrovsky (considered the black sheep of the family), due to Zlata's attitudes before the beginning of the series. Because of this, a power struggle ends up between Riva and her sister for control of the Russian Mafia.
