By 2984 the Space Museum has been renamed "The Museum of Heroes and Legends", and has a whole wing dedicated to The Legion of Superheroes, as well as one to Earth's historical superheroes. That year one of the "Dial H for Hero" H-Dials is stolen from the museum by a petty crook while Chameleon Boy is attending a ceremony there. The villain escapes to 1984 with the help of the Dial, which is ripped to pieces by Krypto the Superdog before eventually being returned to the Museum in pieces by Chameleon Boy, where the Curator reveals they have another one. The Museum appears to have been renamed the "Time and History Museum" some time later, and it is partly demolished by Xotar the Conqueror, a minor Justice League of America foe, on a mission to conquer the 30th century
