Bio: In the days just prior to the explosion of Krypton, the Science Council grew increasingly concerned over Jor-El II's ravings about the end of the world. Thus, Fel-Kar, the leader of the Council, assigned a police detective to spy on Jor-El's movements.
Es was specifically tasked with the duty of catching Jor-El committing any treasonous acts. Es would very likely have caught Jor-El on the latter's mission to retrieve a downed alien spacecraft in the Scarlet Jungle had not Jor-El been prepared with a variety of different defensive inventions. El defeated Es fairly easily, though, and sent the unconcious police detective back to Kryptonopolis on autopilot.
