Superboy Annual #1958-59

In the rugged Rockies, a lone young man named Rex finds himself unexpectedly confronted by Nero, a wild circus wolf on the run. With the wilderness closing in and danger in every shadow, Rex must rely on instinct and grit as he faces a foe far more cunning than any he’s known in years.

In "Valley of the White Giants," explorer Wells Hartford and his photographer Rex venture into the heart of Africa, where they stumble upon a hidden world of towering albino giants and ancient creatures long thought extinct. As Rex prepares to document the impossible, he makes a quiet, solemn decision—capturing the truth may mean letting it remain lost.

In the rugged southwest, young Rex joins a uranium hunt that turns perilous when an earthquake splits the earth and a mountain lion threatens two stranded companions. With quick thinking and a daring swing across a treacherous gorge, Rex races to save them both—before the ground itself decides their fate.

In "Watchdog of the Range," a young boy named Danny rests at a Western ranch when his loyal dog, Rex, springs into action. As night falls, Rex defends the herd from timber wolves, rescues a calf from quicksand, and wards off a deadly eagle and eel—all before collapsing beside Danny’s bed, only to be greeted with a playful, “Get up, sleepyhead!”

In "Rex - - Airline Detective," a clever dog named Rex finds himself far from his usual routine when he’s allowed to ride in the cabin of a plane—only to sniff out a pair of crooks hijacking the aircraft. Stranded after the plane crashes in a fog-shrouded mountain, Rex uses his keen senses to navigate the wilderness and lead authorities straight to the criminals. Back home, his bravery earns him a special honor: a citation and a new title as Airline Detective.

In "The Gold Stampede," Danny, Rex, and Major Dennis bring their act to Gold City’s annual charity fair, where a wild twist turns the celebration into a high-stakes chase. After Rex spots four suspicious men all smoking pipes, he’s stunned when they unleash tear gas from their stems and make off with the charity funds. With quick thinking and a clever trick, Rex uses the chaos to turn stampeding bulls against the thieves, then tracks them down in town—landing a dramatic "Gold Nugget Hotel" sign right on top of them.

In "Rex, Honorary Fire Chief," a determined dog named Rex sets out to win the affection of Queenie, the fire dog, by proving himself during a blazing emergency. When a fire traps kittens in a burning building, Rex rushes in to save them, earning a rare nod from Queenie and a title that might just change everything.
