Knowing that Yautjas have been visiting Earth for their hunting trips for eons, I imagine a story in which Old Norse warriors around the 9th to 13th centuries used meditation and/or natural drugs to put themselves in a state of fearlessness, painlessness as well as extremely increased strength, called "berserkers". These warriors were then the ideal challenge for Yautjas who seeking trophies and glory.
