The Queen Mother, From Aliens

Fans of the Aliens movie franchise most likely remember the Queen alien as a force of intergalactic evil. True, she is the mother who lays the molten eggs, which eventually turn into lots of mean little buggers that seem to exist solely to torment Sigourney Weaver's Ripley and kill everyone close to her. But what is the Queen really doing when she spews acidic saliva and hurls her inner mandibles toward a human's neck? She's protecting her babies, trying to find them safe haven and nutritious food to make them grow into big, strong healthy aliens. Like all good moms, she will take out anyone who is a threat. Focused (perhaps to a fault) on guarding her young, she is the ultimate mother warrior. And she doesn't even expect her kids to buy her flowers on Mother's Day. Now, that's a champ.
