Superboy & the Legion of Super-Heroes #251

In "The Man Who Destroyed the Universe!", Superboy teams up with the Legion of Super-Heroes in a high-stakes adventure that pushes their limits—though the real surprise lies in a familiar face from the future who may not be who he seems. Written with crisp energy and brought to life by Curt Swan’s iconic pencils and Vince Colletta’s sharp inks, this 1979 classic marks a pivotal moment in the series’ run. The cover by Joe Staton and Dick Giordano captures the drama in bold, dynamic detail—a 40-cent comic that still packs a punch.
