10 Most Overrated Star Trek Villains
8. Ba'ul
In the 32nd Century the Ba'ul co-exist with the Kelpiens and everything seems in balance if not harmonious.
But that's not how it once was with the Kelpiens subservient to the shadowy creatures. In the Short Trek, The Brightest Star, viewers are transported to Kaminar where we experience Saru's life before he joined Starfleet and the oppressive regime that his people were forced to live under.
It would be later in the second season that the audience would finally meet one of these beings that seemed like the spawn of a Dementor and a Ring-Wraith and terrified the local populace. Maybe even a bit of Armus in there to spice the mix?
All of the buildup and establishing of Kaminar's past came to very little and a one shot resolution in The Sound of Thunder (E02 S06). It would take the defeat of only one of these beings by Saru to change the equilibrium of Kaminar and usher in a new era. The speed at which their total rule comes to an end is alarmingly quick and before you know it, the Kaminar borders are open and the Kelpiens are chatting away to anyone and everyone in the universe.
