"Newt" from "aliens"

Alone, unarmed and perhaps six years old her character survives amidst an entire colony of some of the deadliest monsters to come out of fiction.

IMO survival, unlike what is presented in the survival gun porn depictions, is seldom fighting the the enemy and threatening forces. Usually the forces arrayed against us will be of a size and form you can't actually fight. Except in rare situations the forces cannot be faced down. You can't square off against a wildfire, or a hurricane or the storm surge it brings. Your only chance is to flee, roll with the punches or, at best, you hunker down and try to ride it out.

The primary traits are not will, physical bravery and a willingness to fight. They are patience, endurance and adaptability.

And for these traits the character of "Newt" is a good example.
