SUPERMAN'S PAL, JIMMY OLSEN 152 (August-September 1972)--1st story, "The Doubled Edged Sword" by Bridwell, Skeates, Sekowsky and Oksner:
Mercifully, Darkseid enters this issue to tell his stooge Morgan Edge that he's had it up to here with his foul-ups. The Dark Lord of Apokolips exercises restraint in not simply destroying the clone right then and there. In fact, Darkseid often seems to leave the killing to others--he's funny like that.
Instead, Darkseid's Omega Vision sends the Double Edge to the Galaxy film library, where the real Morgan is hiding out. However, an Intergang gunsel, who was supposed to kill the original, kills the fake by mistake reducing the clone to smithereens, as the genuine Morris Edelstein looks on. The Man of Tomorrow struggles with the Intergang hitman and the blaster goes off leaving only a scorch mark where the gunsel had stood. Superman apologizes to the real Edge about not believing him months ago, that time when he met him before.
Case closed, no more clone. Now let us never speak of this again.
