Superman #248

In "The Man Who Murdered the Earth!", Lex Luthor unleashes the colossal Galactic Golem, a being forged from cosmic debris driven by an insatiable hunger for stellar energy. With Earth on the brink, Superman must outwit Luthor’s twisted scheme and find a way to divert the Golem’s destructive path before it consumes everything.

In "All in the Mind!", Kryptonian archaeologists uncover a mysterious globe that reveals the forgotten war between Erkol and Xan—its tragic aftermath, the strange birth of children exiled for their unusual traits, and the telekinetic powers they later discovered. When these children, now grown, learn that their long-lost home faces annihilation, they set out to return, only to find Erkol gone and their fate forever changed.

In "Muto Versus the Man of Tomorrow!", Superman of 2466 faces off against the persistent villain Muto in a battle that spans dimensions. Trapped in a submerged Atlantean city, Superman uses his heat vision to reprogram android children and escape the paralyzing sea water, then turns the tide against Muto back on Earth by summoning a super-electric discharge that tears open a space-warp, pulling the villain back to his own realm.
