Kelex is the 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.
