All-Star: 1969: Aquarius Redux
by Dan Swanson, partially adapted from Justice League of America #73-74 by Dennis O’Neil and Dick Dillin 
After the Earth disappears, a handful of strange visitors from other planets — Kell Orr of Xenon and his twin son and daughter Larre and Karre, Tharka the Superwoman, and Regor of Uuz — each independently investigate Earth’s disappearance. Yet are they prepared for the cause of Earth’s disappearance, the living star called Aquarius? Having just battled both the JSA and the JLA, Aquarius managed to trick the heroes into believing he was destroyed, when he actually fled into space with Starman’s cosmic rod. But Starman and Green Lantern guess the eons-old villain’s deception and track him into deep space. When the heroes of Earth rendezvous with the super-stars of space, will even their combined powers be enough to stop Aquarius?

But while the young Xenonian Kell Orr plays the part of Superman on Earth, Superman soon discovers the terrible truth that the world of Xenon is doomed, presenting him with the greatest challenge of his life. Can the Man of Steel tamper with mysterious cosmic forces and save the world that was Krypton’s twin before it’s too late?
