After the defeat of the Borg in Star Trek: Picard season 3, the proposed Star Trek: Legacy spin-off will need a new big bad. Over the course of its nearly 60-year history, Star Trek has introduced numerous noteworthy antagonists to face off against its intrepid heroes. From Captain James T. Kirk (William Shatner) and the Klingons to Captain Jean-Luc Picard (Patrick Stewart) and the Borg to Captain Benjamin Sisko (Avery Brooks) and the Dominion, every Star Trek captain has gone up against a villainous alien species who just keep coming back.
