"Reign is the spark that ignites the eruptions; seismic catastrophes that would wipe out all humans and terraform the Earth."
"Make it Reign" is the twenty-second episode of the third season of Supergirl, and the sixty-fourth episode overall. It aired on June 11, 2018.


After learning the true depth of Selena's nefarious plans for Earth, Supergirl, Mon-El and Alura must come up with a plan to stop her. J'onn prepares to say goodbye to his father.[1]


  • The episode's title is a pun on the idiom "make it rain".
    • Winn uses the same pun in the episode, claiming there to be a "100% chance of […] Reign" after the planet begins to terraform.
  • When Selena and the other priestesses arrive on Earth, it is similar to when Zod, Ursa and Non appear on Earth in the 1981 film Superman II.
  • The personal shield belt Winn creates is reminiscent of the force field belt Brainiac 5 wore in the DC comics.
