Yeah, so I'm just getting back into the swing of things with non-TF comics after about oh a 15 year lay off. So, what's the deal with Superboy-Prime? Why is is sometimes called Superman-Prime? I understand his origin (his Sinestro Corps War issue filled me in) but I don't understand why he, and Earth-2 Superman honestly, are so much more damn powerful than the modern era Man of Steel? I understand he first appeared sometime before/during Crisis On Infinite Earths, are there any other good stories about him? I know he's involved in Blackest Night (not there yet, no spoilers please) and he was pretty bad-ass during the Sinestro Corps War... Umm, I think that's it for now. Thanks!
