"Fort Rozz" is the eleventh episode of the third season of Supergirl and the 53rd episode overall. It aired on January 22, 2018.


As Reign continues to terrorize the city, Supergirl teams up with Saturn Girl, and the two recruit Supergirl’s former enemies, Livewire and Psi, to form a team for a mission to Fort Rozz to recover a prisoner who has information on how to defeat Reign once and for all. Meanwhile, Alex babysits Ruby.[1]


  • Mehcad Brooks is credited, but does not appear.
  • Livewire and Psi both called Imra "Matilda", a reference to the Roald Dahl novel Matilda and its subsequent adaptations, where a young girl displays great intelligence and telekinetic powers.
  • In most Superman comics, Blue Stars emit more energy than both Yellow and Red Stars, Kryptonians exposed to their radiation receive an huge power increase.
  • Reign doesn't appear to have any fears, but Samantha Arias's deepest fear is loosing her daughter, Ruby Arias. While Imra Ardeen's fears were not shown.


  • In the previous episode, Mon-El mentions to Querl Dox/Brainiac-5, to be careful because of the "precious cargo onboard." This dialogue mentions that the Legion's ship has other Legionnaire's on board in cryo-sleep/stasis while Brainiac-5 piloted the ship. Yet in Fort Rozz, the Legion's ship is used again, to travel to the blue star, with no mention of what has became of the inactive members of the Legion. Whether they are still in cryo-sleep/stasis on board the ship or the inactive members have been taken off the ship so it can be used for missions is unknown
