"Though we go forth alone, our soul unites us under Rao's gladsome rays. We are never lost, never afraid. For we shrink not under the sun of righteousness. Rao binds us to those we love. He gives us strength when we have none. And in the darkest places, He guides us. For Rao sees all, feels all, His love eternal. Rao, protect us so that we might protect others. And we shall rise, a fire in His hearth, burning and free."
—Prayer of Rao[src]

Rao is a Kryptonian deity, symbolizing sunlight. After Krypton’s destruction, faith in him was spread to Earth.


Kara Danvers frequently invokes Rao in dire times, such as during the funeral ceremony of her aunt, Astra and during the Music Meister crisis.[1][2]

After Mon-El's sacrifice, Kara Zor-El devoted her life to her heroics as Supergirl, reconnecting with her Kryptonian heritage, as she started to meditate and pray according to the tenets of the faith of Rao. However, she wasn't the only one who was affected by this religion. Thomas Coville, an ex-lawyer saved by Supergirl from the Sabotage of Flight 237, has found hope in his life once again and started gathering others saved by Supergirl. Using knowledge from a Kryptonian capsule he has found, Thomas created the Cult of Rao, spreading the Kryptonian deity's worship on Earth, although Kara Zor-El considered the ways of this cult to be heretical, misunderstanding Rao's message, primarily because Thomas intended to portray her as one of the deities of the pantheon.

Despite this, she went back to the private worship of Rao herself, performing a prayer of the faith alone with the hologram of her mother.

One night, in the bathroom, Samantha Arias looked in the mirror and was horrified to see a vision of herself covered in strange symbols as well as Selena in a hood telling her that she was born from Rao's fire.[3]

In the new multiverse, Chester P. Runk thanks Rao when he learns that Barry Allen is safe.[4]


Rao is seen as a benevolent god, guiding his worshipers and giving them hope. Certain faiths, like the Cult of Rao, consider the earthly troubles and challenges part of Rao's test that his chosen must overcome. The Cult's mysterious benefactors intended to spread the idea of reigning in Rao's name to Samantha Arias and her daughter, Ruby Arias.[3]
