Aethyr is a very powerful godlike entity native from the Phantom Zone.
He consists of millions of souls from two different galaxies.
Theses galaxies merged, and the souls went to another dimension with many kingdoms, one of which is the Phantom Zone.
This character is millions of years old and is in control of all the galaxies, including the Phantom Zone.
He was erased following the collapse of the Multiverse in the 1985-86 Crisis on Infinite Earths limited series, and now, he's considered apocryphal.
Aethyr has appeared in the fifth and sixth season.
She's a disciple of Zod with Nam-Ek. They have bright and green eyes, displaying little emotion and were ruthless and brutal in pursuit of their goals.
They considered humans savages and had little qualm about hurting or killing any that got in their way. When they first emerged from the ship both wore Kryptonian armor, and Aethyr had a bracelet on her right wrist. The bracelet contained inscriptions of the Mark of Zod and Aethyr also wore the mark on her lower back as a tattoo.
She's played by Alana de la Garza.
