The Mum: Ellen Ripley. Sigourney Weaver's seminal sci-fi heroine awakes from hypersleep after the Nostromo incident, having been snoozing for longer than expected. She finds out that her daughter had died a couple of years earlier, aged 66.
The Awesome: Ripley returns to the colonised planetoid LV-426, acting as a consultant for the Weyland-Yutani mission.
She shows her true motherly instincts by taking lone survivor Newt under her wings, and kicking serious ass to make sure the little lass stays safe. Even if that means taking on some pretty hefty baddies with the help of a powerloader.
