He's already turned Superboy Prime into a murderer and currently writes Kal-L as a naive lackey to Alex Luthor with a Parallex-fetish.
Yeah, but who the hell was Superboy-Prime, anyway? I'm all for giving respect to characters with history, but the thing here is this: at least as a villain Superboy-Prime has a personality...and something to do. It's not like he was Hal Jordan, who is universaly beloved and has a history of writers giving him a strong characterization and a real personality, and who, further, fulfills a niche in DC ecology.
I shed a tear when HAWKWORLD and LONGBOW HUNTERS made Hawkman and Green Arrow unrecognizeable and conceptually divorced, not to mention unoriginal trend-trollers. But why are we getting all sentimental about Superboy-Prime, anyway? My attachment is to the Pre-Crisis DC history, and Superboy-Prime was a character created for Crisis that didn't survive Crisis.
Wait...you mean FAMILY GUY may not be 100% original? My world no longer makes sense.
Going with what the others said... plus as we saw of his upbringing, don't see how anything there, or that he should've been being taken care of by Kal-L and Earth-2 Lois, including being trained in the use of his powers by Kal-L while they were in that dimensional "paradise" all those years, would result in what I saw in IC ("jealous" of some clone that's not been around as long as SB-Prime has and who's had a rather tumultuous life during his short existence, plus a very sloppy use of his powers? Uh, yeah...whatever...).
Re: Family Guy: I'd settle for it being *1%* original. ;-)
