Zrinka and her younger brother Costel were in the marketplace of Novi Grad while, in the mountains overlooking the city, the Avengers led an Attack on the HYDRA Research Base. Missile fire started to rain down on the city streets from the HYDRA Research Base; the Iron Legion entered the city and asked the citizens to find shelter for their own protection. As the citizens began to throw rocks at the robots, Zrinka ran to Costel and grabbed him in a protective manner.
Days later, a Helicarrier deployed Lifeboats to evacuate Novi Grad, as the city rose above the country of Sokovia. Zrinka was already onboard, but she lost sight of Costel. She began screaming for him. Her cries were heard by a man who left the Lifeboats to find her brother. Zrinka and Costel were reunited aboard the Helicarrier.
- In a deleted scene, Zrinka received an expensive stolen dress from Paris and a toy for her brother from Quicksilver before Costel tells him that "Iron Man" is waiting for him and his sister in a church.
