After spending some time together, Clark brought his cosmic twin Superboy back to the farm, introducing him to his parents John and Mary. Instead of running the local grocery store, named Jacobsen's General Store instead of Kent's. Appearing different from his own folks, Superboy still sees the same inherent goodness with this couple as that displayed by how parents Jonathan and Martha.
Interestingly, during this meeting, Superboy is curiously silent over Mary's statement "Maybe Clark came from that other world, too!" Perhaps this was due to the fact that he surmised that a Krypton-Two may be drastically different from his own homeworld, and hence reluctant to provide details on such a world for fear he'd be misleading Clark.
Regardless, the caped lad and the Kents observe and assess Clark's aptitudes towards amazing abilities of his own. While his strength is tremendous as our his telescopic and super-hearing, his x-ray and heat vision like the power of flight would remain dormant until his young adulthood. Still, being faster than a speeding bullet, more powerful than a locomotive, able to leap tall buildings in a single bound, Kent was the pinnacle of human perfection on his planet.
As the two lads part, with Superboy resolved to return to Earth-One now that he's finished his tutelage of his counterpart, Clark adopts his own costumed alias. However, his intentions are quite different.
Finally convincing his father to allow him to join Bartletts Traveling Circus, Clark as the Masked Wonder amazes crowds while disgused iin a mask and acrobatic togs. However, after averting a potential disaster using his abilities, the Wonder realizes his short-lived career is futile and he must take a path similar to that of Superboy, returning to the farm.
Once Clark assists his twin to return this his home universe, the lad decides to adopt a similar alter ego in the form of Superman, waiting until he's fully developed when he moves to Metropolis. On Earth-Two, the Man of Steel was the first and foremost of costumed crimefighters that inspired generations of superheroes, including that of Superboy back on Earth-One.
Now, back to the subject at hand, the twin Kryptonian crusaders. How, though, would the now adult Supermen react when they finally met, both clad in the same uniform and following similar careers? Interestingly, not very well at first...
