Kelex is the design name of multiple robotic assistants from Krypton.
One Kelex appeared in Kara's dream, induced by an alien plant. It introduced itself to Kara as her medical attendant, when she "woke" up, much to her confusion. In order to calm her down, Kelex told Kara that her confusion would abate as her temperature stabilized. It then prompted her to get dressed.
During Non's takeover of National City, Kara arrived at the Fortress looking for Superman. Kelex informed her that her cousin was dealing with a matter offworld. Kelex refused to give Kara information on Myriad, and instead directed her to a hologram of her mother.
When Hank Henshaw infiltrated the Fortress, Kelex threatened him with disintegration if he did not identify himself. Henshaw poured blood stolen from Kara on the console, causing Kelex to identify him as Kara, and thus freely provided information on the Medusa virus. Henshaw subsequently reprogrammed Kelex to attack Kara on sight, forcing her to destroy it.
