On a certain Earth, the only superhero Superman, Kal-El, was elected President of the Earth after leading the Earthlings to defeat the invader Darkseid.
Decades later, his old enemy Lex Luthor gave him research information about parallel universes. In other parallel universes, there are many superheroes who also have special abilities beyond ordinary people.
With curiosity about other "superheroes", Superman stepped down as the president of the earth, drove the spacecraft "Castle of Solitude", and came to another parallel universe without Kryptonians.
