Genkai is still one of these as a seventy-plus year-old woman, and, when she was younger, she helped Team Toguro with the Dark Tournament, her being the only girl on that team.
She's a 50-70 year old woman in the body of a five-year-old girl (and plays up the innocent girl look a lot.) She then 'kills' Lestat by stabbing him repeatedly after she poisons him.
The scene where Michael Myers steals a knife from Mrs Elrod happens later, and is edited to suggest he kills the old woman instead of Alice the girl down the street.
