First designed by H. R. Giger in 1979, the menacing star of the Alien series is a unique xenomorphic being. Since the species was reawakened by the crew of the Nostromo Spacecraft, the sole survivor, Ellen Ripley, has battled to keep humanity safe from alien destruction.

In Alien³, Ripley and her late crew crash land on a prison planet after their escape from the alien stronghold. As the prisoners are slowly killed, Ripley discovers that the reason for their sudden breakdown is an inhuman stowaway, and a desperate plan is devised to kill the alien menace. What Ripley soon learns is that there is more to her alien encounter than she imagined.
