Aethyr is a villain from Krypton, and a loyal servant of Zod. She and the man Nam-Ek arrived in Smallville during the second meteor shower with the intent of destroying Kal-El and opening the passageway for Zod to arrive on Earth from the Phantom Zone. She is currently imprisoned within the Zone once again due to Clark trapping she and Nam-Ek in the same passageway that was intended for Zod to escape from.
