Vala is a cloned member of the Kandorian Army and a recurring antagonist in the Ninth Season of the CW TV series Smallville. She appeared in 4 episodes throughout the season.
On Krypton, Vala was the sister of Faora and was specialized in cybernetic engineering and an M.D. in the Kandorian Army. She, like the other Kandorians, donated a sample of her blood that was stored inside the Orb that would ensure Krypton's survival.
Vala was one of hundreds of Kryptonian clones created by the Orb when it was opened by Tess Mercer. Vala soon discovered that she lacked the powers, that Kryptonians would normally possess under a yellow sun. Wanting them, Vala and a few other clones began experimenting on humans to find the answers they were seeking.
She experimented on two humans Dr. Bernard Chisholm who was resurrected and Daily Planet reporter John Corben who was transformed into a cyborg. Unable to find results, Vala and the other scientists abandoned the experiments.
Clark Kent and Chloe Sullivan created background information for Faora, Vala and several other Kandorians as they attempted to be integrated into human society. With access to a fake I.D. and passport, Vala used them to get a job at a bookstore in Metropolis. She met Faora and Clark outside the store who she called Kal-El as she was not use to human names. Faora believes their lives would be better if they had their powers. Vala, on the other hand, waved the matter aside, as she knows that Clark will be there to protect them and the humans.
Faora warns Vala not to get her hopes up about Clark as he is in love with a human. Faora invites Vala out for a coffee after she closes up the bookstore. Vala gets her keys from the counter when the front door opens, but Vala sees no one. After locking up, she saw a masked man who kidnapped her and put her to sleep before she could escape. When Vala wakes up, she is imprisoned in a container, wearing just her underwear, along with two other Kandorians.
