Superman, Vol. 2

Clark has volunteered to help Lana Lang put up a fence at her home, and he gets the job done in no time, thanks to super-speed and heat vision. Martha and Jonathan come up with a picnic basket, and the four have lunch together.

Suddenly, Superman perceives a disturbance at the nearby Limestone rock quarry and flies off to investigate. Upon arriving, he finds four super-heroes from the future known as Brainiac 5, Sun Boy, Invisible Kid and Blok. Superman's powers go out of control suddenly and he begins firing heat vision at this futuristic Legion of super-heroes. The Legion meanwhile, believes that Superman is actually Superboy, a time traveling hero that has teamed up with them in the 30th century.

Everybody gets into a big fight, but before long cooler heads prevail, and Brainiac 5 attempts to explain his presence in this era. Originally, they tried to use the Time Trapper's time bubble to travel backwards in time to Superboy's native era. However, they wound up in a strange pocket dimension instead. Superboy turned out to be a traitor and tried to kill them. Other members of the Legion of Super-Heroes escaped and tried to return through the time stream, however, they ended up here in this parallel universe. Superman tries to explain to them, that in this reality, he never became Superboy and he has no idea who the Legion of Super-Heroes even are.

At that moment, Superboy appears above them and threatens to end their lives.
