Necrolai is a former antagonist turned secondary protagonist and ally of the TV series Power Rangers Mystic Force, She was a member of the circle of accolytes of Octomus the Master. She was also the queen of vampires.
Before her redemption, Necrolai was a cold and calculating individual known for using dark magic. During her battles against the Rangers, she was mostly affable but wary about their powers.
Her daughter, Leelee, is the only person to whom she has shown kindness. It was not until meeting Itassis, however, that she could realize the error of her ways and accept the Rangers as her allies.
After returning in her human form (Nikki), she has been shown as a kind and caring woman, especially to Leelee.
