Berry Lou (Brinke Stevens) was a villainess from the 1989 horror-comedy, Transylvania Twist.
Berry Lou was an evil vampiress from a flashback scene with vampire hunter Victor Van Helsing. She is shown seated with Victor during a night out, and it is at that moment that she reveals herself as a vampiress and tells her true age: 1900. Just as Berry Lou is about to insert her vampire fangs into Victor, the hunter hands the villainess a vial, suggesting that they should have a drink together. Berry Lou drinks the contents of the vial, which is revealed to contain holy water, killing the vampiress instantly.
