Kelex

Kelex (named KELEX) is the Kryptonian AI program that runs Superman's Fortress of Solitude.

Biography
The original Kelex was but one of many robotic assistants in service to the House of El in the years before Krypton's destruction. Kelex was destroyed when the planet Krypton exploded due to an unstable core.

The creation of the Fortress of Solitude also created a new Kelex. Sometime after the creation, Superman studied the robot and created a dozen more, storing them in the Fortress for protection and training.

In 1999, when Jor-El was teaching his son Kal-El about heritage, Kelex assisted in the explanation.
