Following the defeat of two huge threats to the Federation in Star Trek: Picard season 3, Star Trek: Legacy faces a big 25th century villain challenge. The final season of Picard brought the Star Trek: The Next Generation era to a fitting close, but in doing so, it killed off one of Starfleet's most fearsome foes, and significantly weakened another. As Picard showrunner Terry Matalas looks toward the future with his proposed Star Trek: Legacy series, he'll have to create a brand-new enemy that can stand alongside, or even overshadow the Borg Collective and the Changelings.
It was absolutely right for Star Trek to end the story of Admiral Jean-Luc Picard (Patrick Stewart) with the destruction of the Borg Collective. The Borg's surprising Star Trek villain team-up with the rogue Changeling schism was an added bonus, but it's hard to see where else the franchise can take the Dominion Founders. The end of Star Trek: Deep Space Nine set up a more peaceful version of the Changelings, led by Constable Odo (Rene Auberjonois) from whom Captain Vadic (Amanda Plummer) and her schism rebelled against. The only thing left now is to explore new territory when it comes to Star Trek villains.
