Under Kobra’s orders the cultists threatened to activate bombs implanted in their bodies, killing themselves. Rather than allow the bloodshed the judge and Director Bones of the D.E.O. agreed to let Kobra go free for the time being. Atom-Smasher and Black Adam were outraged, and both agreed Kobra should have been killed for his crimes then and there. Terrific and the rest of the JSA vehemently opposed their viewpoint, so the duo quit the team. “Dr. Fate” then removed his helmet and revealed he was really the JSA’s nemesis Mordru.

The Spirit King possessed Flash, and under his control he nearly killed Mr. Terrific before Spectre banished the undead army and destroyed the Spirit King. Terrific had a near-death experience, seeing his wife in Heaven, and being introduced to the soul of his unborn son.
