Aethyr is a recurring villainess in the WB TV series Smallville.
She was portrayed by Alana de la Garza.
Aethyr and Nam-Ek were the Disciples of Zod as they were his closet allies during the final years on Krypton.
After Zod was sentenced to the Phantom Zone for his war crimes, the disciples escaped Krypton's destruction with the Brain InterActive Construct in the Black Ship and made its way towards Earth. It laid dormant in space until it reached its destination.
The Black Ship crash-landed to Earth after one of the Stones of Power was stained with blood belonging to Genevieve Teague. The Kryptonian vessel was hidden in a meteor shower that struck Smallville and landed in a field witnessed by Lana Lang.
Exiting the ship, the disciples startled Lana with their appearance, and they attacked police officers who arrived at the scene. Aethyr and Nam-Ek used their heat vision to dispatch the officers. They killed mostly all of them but left a few survivors including Deputy Harris and Greg Flynn.
She and Nam-Ek super speed to the Katwatche Caves where they encountered Lex Luthor and asked if he was Kal-El.
After grabbing him by the neck and saw Lex bleed, Aethyr stated he was not Kryptonian and quickly left the caves. The pair traversed Smallville in search of Kal-El, leaving a trail of destruction and brutality in their wake.
The disciples then went to the Smallville hospital looking for Kal-El, Lois confronts them, and they choke her and throw Jonathan across a room. Lana stumbled in and as they were about to kill Lois, tells them she knew where Kal-El was.
She led them to the Luthor Mansion where she tries to trick them into entering Lex's vault full of kryptonite-rock artifacts. The Kryptonite stuns and pains the pair, but the disciples manage to seal the vault and regain their composure.
Angered by the deception, Aethyr threw Lana across the room, knocking her out. Before the aliens could kill Lana, Clark arrived. The disciples ask Clark to join them wanting to transform Earth into a New Krypton but he refuses.
Seeing no other choice, Aethyr throws a bracelet off her arm to form the Phantom Zone vortex to trap Clark in it. However, Clark strongly resists; they fight briefly and Clark manages to trap them instead. The disciples were trapped in the vortex which forms into a giant shard of crystal that flies out of the window and into space.
Exiled to the Phantom Zone, Aethyr and Nam-Ek traversed the barren landscape plotting their revenge against Kal-El. They came across Kal-El and Raya, Jor-El's former assistant. Raya pretends that she is using Clark to escape and they start to fight.
Nam-Ek battled Clark while Raya and Aethyr fight.
