Effie is a non-playable minor character in the Street Fighter games. She is Necro's Russian girlfriend who first appeared in his ending in New Generation, and rescued him. In 2nd Impact and 3rd Strike, she appears as a member of the Judgment Girls. She also appeared in some official artwork and also made a cameo appearance in Felicia's Capcom Fighting Evolution ending.
Effie met Necro while they were captured by Gill's organization, Illuminati. During that time they became fast friends, and soon lovers. During their time with the Illuminati, they were experimented on as part of the "G-Project". Effie is blonde and wears a red outfit; she is loyal to Necro and also mimics some of Necro's actions. In 3rd Strike, Effie and Necro are now fugitives after Gill finds out Necro survived. Gill orders his organization to hunt them down. While running away from members of the organization, they reach the top of a train trying to escape out of Russia. Necro fights them off and succeeds. Then Necro realizes that, even though he's a mutant, he can use his abilities to protect the woman he loves.
