Outlander

Vikings, year 509. A spaceship crashes in ancient Norway. Out of it emerge a humanoid warrior named Kainan and a bloodthirsty creature known as the Moorwen, a savage beast bent on avenging the extinction of its race at the hands of the warrior's army. As the Moorwen devastates Viking lands, killing anyone who gets in its way, Kainan, combining his advanced technology with ancient weapons, sets out to train a group of primitive but fierce warriors. The goal is clear: destroy the brutal creature.
