How to Tame a Wild Volcano - Morgan Edge has ordered Clark Kent to cover a volcanic eruption, and not to help its victims. That doesn't stop Superman, although he has a hard time doing his job without breaking trespassing laws. Bouts of weakness and a sand duplicate of himself don't help, either.
Fabulous World of Krypton: Prison in the Sky - Jor-El has ideas for humane prison reform, but to see them pass, he'll need to overcome the power and authority of Tron-Et.
