|Ghoulies (1985) [Rebecca]: Falls down a staircase while arguing with Peter Liapis. She later comes back to life as a zombie, but is killed again during a fight between Peter and Michael Des Barres; she is brought back yet again, but since the ghoulies are shown hiding in the car as she and the others are escaping, it's implied that she'll be killed even one more time.
