World's Finest Comics #191

In "Execution on Krypton!", Superman [Kal-El; Clark Kent] is thrown into a desperate journey across space and time when Jor-El and Lara suddenly appear, their words sending shockwaves through him. With no time to question their intentions, he leaps through the void and arrives on Krypton, where the planet’s fate hangs in the balance. As the tension mounts, the presence of Batman [Bruce Wayne], Perry White, James Gordon, General Hill, and Calox adds a new layer of urgency to a mystery that reaches far beyond the stars.

When Fixer Bannon sets off an explosion targeting Dick Grayson, he hopes to prove his theory that the young acrobat is secretly Robin—only to unleash a danger that could leave Dick stone-deaf, putting both the boy and his crime-fighting alter ego in peril. With Commissioner James Gordon racing to protect him, the stakes rise as Robin’s greatest challenge isn’t a villain’s plan, but the silence that follows the blast.
