known as Earth-247, each of her children themselves have children with speed-based abilities. One, Jenni Ognats, grows up to become the Legionnaire XS, while the other, Bart Allen, is born with an accelerated metabolism that rapidly ages him, and is sent back to the 20th century where he is cured by Wally West. He remains there as the superhero Impulse under the tutelage of Max Mercury, and later becomes the second Kid Flash as a member of the Teen Titans. One year after the events of Infinite Crisis, Bart becomes the fourth Flash until he is abruptly killed by his clone Inertia and the Rogues. Wally then retook the identity of the Flash. Bart would later be resurrected as Kid Flash by the Legion of Super-Heroes in the 31st century to combat Superboy-Prime. JLA/Avengers Barry Allen appears in issue 3 as the Flash in the JLA when the two realities start changing, along with Hal Jordan. When the two teams see their real futures, Barry witnesses his death during Crisis on Infinite Earths as the Grandmaster shows the heroes how reality should be, but nevertheless resolves to help restore the timeline as it is not his place to play God. He talks with Hal Jordan over the similarity of their situation, stating that dying could not be so bad so long as they have left a legacy for others (Wally West and Kyle Rayner, in their cases) to fight for what they believe. He helps the team get into Krona's base by using his running on a treadmill to pass the ship through the dimensional barrier. With the Wasp, he is ordered by Captain America to find ways through Krona's defences, and alerts the group to a probably lethal force field. During the final battle, Barry saves Hawkeye from being killed when the Absorbing Man breaks the ground beneath him, but both of them are blasted and apparently killed by Dreamslayer. At the end, it is revealed that Barry got the two of them out alive and at Captain America's suggestion they laid low and because of this, Hawkeye is able to destroy Krona's machine with a TNT arrow while Barry distracts him, then Barry takes the 12 items of power. As a result, reality is restored, Barry disappears and Wally returns. Post-Crisis appearances Wally West, wracked by grief for the loss of his unborn twins at the hands of
