I can provide some general information on the topic.
In the context of narcissistic behavior, the "new victim" refers to a person who becomes involved with a narcissist after a previous relationship has ended or while the narcissist is still in a relationship with someone else. The selection of the new victim can vary depending on the individual narcissist, and there is no one-size-fits-all answer to whether the new victim is similar to the previous one or not.
Narcissists are primarily driven by their need for admiration, control, and validation. They often seek out individuals who they believe will fulfill their emotional needs and provide them with the attention they crave. While some narcissists may be drawn to individuals with specific physical appearances or certain character traits, others may be more interested in finding someone who complements or contrasts with them in various ways.
It's important to note that narcissistic behavior is complex, and the dynamics of a narcissistic relationship can vary widely depending on the individuals involved. Narcissists may use manipulation and emotional abuse to maintain control over their victims, regardless of whether they are similar to each other or not.
If you or someone you know is experiencing or has experienced abuse in a relationship with a narcissist, it is crucial to seek support from friends, family, or professional counselors who can provide assistance and guidance.
