JulianPerez, you might want to take a look at my post way back on June 16, 2004 (and I've voiced similar thoughts on the DC Message Boards even before this):
https://www.supermanthroughtheages.com/phpBB2/viewtopic.php?t=924Superboy-Prime actually has some fascinating possibilities. First, his personality is significantly different due to his upbringing -- ESPECIALLY his unique experience of growing up in a world where nearly EVERYONE knows that "Clark Kent = Superman". Clark could have been justifiably resentful of his "fictional" namesake, but instead of rebelling he went along with the laughs. From DCCP #87 we can see that Clark was somewhat of a "class clown".
But the destruction of Earth-Prime devastated poor Clark. Remember, his heroic stand with Kal-L against the Anti-Monitor was a suicidal act of despair -- he didn't have anything to go back to "over there", so why not stay and fight? One hopes by now Superboy-Prime has learned to deal with this grief, but it would be an interesting character aspect if his normally-enthusiastic and upbeat nature is shadowed by lingering guilt for not saving his world, the Kents, his girlfriend, etc.
Young Clark grew up during the 1970s and early 80s in New England, possibly Hampton or nearby Hampton Beach, New Hampshire. Jerome Kent had a home electronics and computer business, while Naomi Kent was an attorney. Apparently he also went to a private school. Compare that to Superman's small town upbringing by Ma and Pa Kent. Perhaps Prime would have a more "Eastern Liberal" vs. "Middle-America" political outlook? What other social influences might shape him differently?
Powerwise, it's hinted that Superboy-Prime might be "in-between" the Earth-1 and Byrne reboot Supermen. His powers arrived when he was 16, unlike the Silver Age Superbaby who immediately exhibited superpowers upon arrival on Earth or the Post-Reboot Superman who never was a Superboy (though Prime's powers might have been triggered early by the Crisis). While we don't know if Superboy-Prime would have eventually rivalled the Earth-1 Superman's power, he had one distinct advantage -- his powers weren't immediately affected by red solar radiation. It's unclear whether Superboy-Prime could function indefinitely under a red sun, or if he was running off his "solar battery" like the Byrne Superman, but Superboy-Prime had a lot of potential. (I can accept sacrificing some overall power for greater versatility.) Plus, since he was an avid reader of Superman comics, he already had a pretty good idea on how to use his powers! :wink:
We can assume post-Crisis Kryptonite wouldn't affect Superboy-Prime, since the Byrne Superman was similarly immune to the Pocket Universe variety. So if the new Post-Birthright multi-colored Kryptonite doesn't phase Prime, then he's ONLY subceptible to magic and mind-control.
As for his knowledge of DC heroes -- we can see from DCCP #87 that he was VERY familiar with Superboy/Superman stories, and knew Hal Jordan was a test pilot. Also, since Crisis #7 was apparently released in early July, 1985 (despite the October cover date), Superboy-Prime would have just read it before gaining his powers. No wonder he thought Kara's death was an "Imaginary Story" -- he started reading about the Crisis MONTHS before it ACTUALLY BEGAN! :shock:
Granted, he wouldn't know anything about Post-Crisis characters. ("Jason's dead? I barely got to know him... who's Robin now, and where's Barbara?") And there's a lot that's been completely altered -- thank Rao he doesn't have to convince Power Girl to drop all that Atlantean origin nonsense now. :wink: But that still gives Superboy-Prime a LOT of "inside information", and he's bright enough to investigate and figure out anything he doesn't know.
For all these reasons, I really like Superboy-Prime. I just hope DC does him justice, and DOESN'T kill him off simply to "shock" Conner Kent into becoming a "true" Superboy. I would rather have Prime stay in the Paradise Dimension indefinitely rather than have THAT happen... and I still fear DC will do just that.
