Mother Russia (Olga Kurkulina) is the secondary antagonist in Kick-Ass 2.
Katarina Dombrovski is a former KGB member and Gulag inmate. While in the Gulag, she exercised and trained everyday. Also, she is mentioned to have eaten her cell-mate. At Javier's (John Leguizamo) suggestion, she is hired by The Motherfucker and becomes part of his Toxic Mega Cunts as the super-villainess, Mother Russia. Mother Russia is easily the strongest and most skilled member of the group; She is able to effortlessly shrug off Hit Girl's (Chloë Grace Moretz) blows and easily eliminate 10 police officers. As an ex-KGB agent, she is an expert in both armed and unarmed combat and can use virtually anything as a deadly weapon. Mother Russia is the highest paid member of the gang ($50,000 per week plus expenses). She stabs Colonel Stars and Stripes (Jim Carrey), puts him in a headlock, snaps his neck, and then decapitates his corpse.
She later joins the Mother Fucker (Christopher Mintz-Plasse) as he plans to attack and rape Night Bitch (Lindy Booth). When the police arrive, she brutally murders every single one of them and later flees the scene with the Toxic Mega Cunts.
In the climatic final battle, Mother Russia faces Hit-Girl and proves to be more than a match for her, single-handily subduing the teenager. She puts Hit-Girl in a headlock and presumably was about to snap Hit-Girl's neck the same way she did to Colonel Stars and Stripes. However, she meets her end when Hit-Girl produces a syringe, which Mother Russia assumes to contain poison, but is in fact full of adrenaline. Mother Russia injects Hit-Girl with the adrenaline, giving her increased strength and speed. Hit-Girl quickly overpowered Mother Russia, and broke out of the headlock. She then swiftly stabbed Mother Russia multiple times with glass shards. Before finishing Mother Russia off, Hit Girl tells her "I would've thought a cunt like you could handle all those pricks", in Russian (you will not shot me you superhero and superhero help people).
