Now the epic one is Gargoyles, where many Trek actors are in it (including Mulgrew, Spiner, Dorn, and Brooks).
Two of the main villains are played by (and they work together sometimes), weirdly enough, Frakes and Sirtis.
There’s an episode where Frakes’ character is out of jail and threatens revenge upon the main characters, and one responds, “With you and what Starfleet?”
