Firstborn victims are a type of enemy introduced in Infamous: Festival of Blood.
Firstborn Victims are pedestrians who are grabbed and bitten by a Firstborn and are turned into zombie-like Vampires. They will run after Cole and try to jump on Cole's back and bite him.
Firstborn victims can be cured, if Cole manages to kill the Firstborn which infected the victims, they will return to their normal selves.
The victim's skin becomes gray, and they walk slowly, similar to a zombie. Some may also wield baseball bats or other similar weapons. Some may also carry clubs which look very similar to the caveman club but smaller.
