part to Batman, Captain America and the Atom having discovered the nature of the game in time to ensure that the League wins instead of declaring a draw—Krona strikes down the Grandmaster in a rage, draining his knowledge to learn the identity of the being he spoke of, allowing him to summon Galactus. He then repeats the process with Galactus, but the Grandmaster tricks him and uses the power of the collected items to lock Krona at the multiversal junction point, having linked the two universes together. The Grandmaster's hopes are dashed, though, when it becomes evident Krona would continue even in his extremely dangerous location in his insane quest to view the birth of a universe despite the risks posed to himself. Even from there, he continued his onslaught to destroy both the Marvel and DC universes to create a new one, so that he could watch creation first-hand. He forces them closer together, causing reality to warp wildly, and even making items and people switch worlds. He is briefly disrupted by the efforts of the Scarlet Witch and Green Lantern, but then continues his experiments. After being told what has happened by a dying Grandmaster, the two teams get to Krona's stronghold, led by Captain America and coordinated by the Martian Manhunter, pitting them against various brainwashed villains and increasing the scale of his 'recruits' as the heroes defeat each wave. He nearly kills all the heroes of both teams as they penetrate his final wave of defenses—even with Superman wielding Captain America's shield and Thor's hammer— but Hawkeye and the Flash (Barry Allen), who had earlier faked their deaths, stop his plan, Hawkeye firing a TNT arrow at Krona's machinery. The blast was immense, and ended up sucking Krona into the universe seed called the Cosmic Egg. The Spectre then pushes the worlds apart and reality returns to normal. This egg is kept and studied in the JLA headquarters. Its fluctuations are a matter of intense scrutiny in the "Syndicate Rules" storyline, during which it is speculated that the reconstruction of the universes also altered the original 'rules' that allowed the League and the Syndicate to always win on their home ground, requiring each to fight harder in the future. After the League believes they have the situation under control, they implement tighter scans on the egg, to register alarms at even the most minor of fluctuations.
