Synopsis for “The Superman of the Future!”
A number of reporters have gathered to witness Professor Wright test his Time-Cabinet – a time travel device. Superman has agreed to help test the invention and seemingly disappears when the professor sends him to the year 100,000 A.D. When the Man of Steel reappears, his head is much larger and his fingers are longer – this man claims he is the Superman of the future and that he is taking the place of his contemporary counterpart for a day. He tells everyone present that he has come to the past in order to prevent four disasters from coming to pass.
The first three disasters come to pass as ordained, and all who were present during the Time-Cabinet display travel with this Ultra-Superman to see if he can prevent them from happening. All three times he fails to stop the disasters from happening, proving to himself that he cannot change the past and revealing that the final disaster is the assassination of the President of the United States.
When the intended assassination occurs, the culprit, Dirk Folgar, exposes himself as a spy when it turns out the Future-Superman was the only one riding the car and was uninjured. The Ultra-Superman turns out to be the modern day Superman, and that the whole Time-Cabinet display was a hoax perpetuated by Superman with the aid of Professor Wright to expose the spy, and that all the three previous disasters were additional hoaxes that were prepared by Superman. With Folgar’s plot foiled, he is arrested by the police.
