The Best of DC #21

In a pivotal moment of World War II, President Franklin D. Roosevelt convenes a secret meeting with British agent Smythe, setting in motion the creation of the Justice Society of America. With the fate of England hanging in the balance, a roster of Earth’s greatest heroes—Green Lantern, Superman, Batman, and others—unites to thwart Hitler’s naval invasion force and the deadly Valkyries in a high-stakes mission that will define their legacy.

When the Justice Society of America gathers for their monthly meeting, Hawkman stumbles upon a mysterious metal shield from ancient Macedonia—its presence a puzzle none can explain. Wonder Woman deciphers its markings, sparking a journey through time via the Magic Sphere that reveals a terrifying pattern: modern inventions vanish without a trace. The JSA rushes to the aid of their wounded friend, Professor Zee, who claims the phenomenon is his creation—but warns that a new assistant, Per Degaton, may be behind the growing anomaly.

In "The Day That Dropped Out of Time, Chapter 2," Flash [Jay Garrick] races against time to save a professor’s life, tracking down penicillin hidden in a time capsule within Colossal Caves—immune to the temporal chaos unfolding. There, he confronts Per Degaton and his men, only to be captured and locked inside the capsule itself. Using his speed to break free, he escapes, secures the medicine, and rushes to deliver it, leaving the mystery of Degaton’s true target unresolved.

In "The Day That Dropped Out of Time, Chapter 3," Per Degaton's relentless march through Gotham takes an unexpected turn when his forces target an insurance company's gold vault—only to be interrupted by the Atom [Al Pratt]. Trapped in a deadly exhibit filled with perilous contraptions designed to cause instant death, the Atom must use his wits to escape, uncovering a crucial clue: Degaton has altered a past battle. With that revelation in hand, he races back to the hospital to warn others—before time itself unravels further.

In "The Day That Dropped Out of Time, Chapter 4," Hawkman [Carter Hall] arrives at the Mayor's office just as Per Degaton’s army of tanks emerges from the city’s subway, seizing the Mayor and trapping Hawkman in a collapsing antique shop. With the bed closing in, Hawkman fights back, narrowly escaping with the Mayor to restore order.

In "The Day That Dropped Out of Time, Chapter 5," Dr. Mid-Nite races against time to stop Per Degaton’s plan to rewrite modern science from the ground up. With the Hall of Science under siege and key scientists captured, Mid-Nite narrowly escapes a deadly trap, uses his blackout bomb to free the hostages, and rushes back to the hospital to ensure the professor’s safety.

In a quiet hospital room, Professor Zee recovers just enough to warn the Justice Society of America that the villain Degaton has altered history—changing the outcome of the Battle of Arabela in 331 B.C. With the fate of the past hanging in the balance, the team must race to the Colossal Caves and activate the professor’s time machine, but Green Lantern hesitates, fearing that a full JSA arrival might trigger Degaton to destroy it. Now, Alan Scott must decide whether to go alone—or risk everything to restore history, one moment at a time.

In "The Day That Dropped Out of Time, Chapter 6," Green Lantern [Alan Scott] races to stop Per Degaton’s plan, only to be knocked unconscious and wake up in the distant future, where the Justice Society of America awaits. With the time machine on the verge of detonation, the team must decide how to alter the past—before the future collapses.

In a final twist of time and fate, the Justice Society of America finds themselves swept back to 331 B.C., where they aid Alexander the Great’s army against a mysterious threat—only to earn a legendary reward before vanishing once more. As the past reclaims its course, the modern world resets, and a strange shield from antiquity reveals its true meaning, leaving Professor Zee and Per Degaton to ponder a dream that may have been more than just a dream.

In "The Big Super-Hero Hunt!", the Sportsmaster strikes again, snatching the famed Parker Trophy right under Black Canary’s watch, forcing her to go on the offensive. Meanwhile, Starman races to rescue Wildcat, who’s been taken by the Huntress—only to discover the unlikely twist that the two villains are now married, and their next target is him.
