Alien Introductions. The trio begin a new series - focusing on the introduction on now-familiar alien species. In this inaugural installment, the trio look at the first episodes featuring the Klingons ("Errand of Mercy" TOS) and the Founders ("The Search, Parts 1 and 2" DS9). How do the "Kling'n's" differ from the ones we've seen throughout the franchise? Commander Kor acts as our first Klingon character, but seems a far cry from those warriors of TNG and DSC. Deep Space Nine introduces the leaders of the Dominion in their season three opener, which will change the course of the series and last until its finale. What do you think of these first episodes? And what changed/kept the same?
