Wow, this is amazingly similiar to an idea I'd been batting around for 
 some time.  Quincy as Luthor, it's bleeding obvious when you think about 
 it.
 
 Now, I did have a problem with Superman's internal dialogue at the 
 beginning.  He sounded too immature, too cocky.  If you wanted to 
 portray him as treating this as routine there are better ways.  For 
 instance, you could have him think about Lois or the next story he was 
 going to file as Clark Kent.

I was inspired in the internal dialogue by Superman Red. He seems to act
somewhat funkier than Blue, and in a recent issue he even said that the good
guys always win. 
  

 I just don't see Superman being so cocky.  At heart, he's a humble man, 
 in contrast to Batman's absolute arrogance.  He knows full well that you 
 can't always depend on the good guys winning.

That's how he always ACTS, but as I said, Supes Red led me to believe that
maybe he's more lighthearted than we all thought. But, seeing as how you and a
number of other people have complained about this, I should probably tone down
the cockiness.
  

 How does Superman immediately know to go to Genom, anyway?  I'm assuming 
 Luther is using another clone body to be Quincy, and Genom probably 
 didn't even exist when Supes was locked up.  Superman shouldn't have the 
 first clue where to go looking for Luthor.  In fact, I would think his 
 first instinct would be to go look for Lois.

I never said he went straight to Genom. I used "leaped Genom Tower in a single
bound" because it sounded cool. He only lept OVER the Tower, he's not going to
it. In fact, his first instinct IS to look for Lois. But she's dead (old age)
and other people are living in their apartment.
  

 Just as a note, I believe Kryptonians may not age the same as humans.  
 IIRC from "World of Krypton", they used to use cloned body parts to 
 extend their lives, but eventually turned to genetic manipulation.  The 
 thing is, since Kryptonians shaved their heads, they never bothered to 
 adjust the genes controlling hair.  That's why all future Superman 
 stories show him growing grey hair.

Well, he's going to look somewhat older than he actually is. Fourty-odd years
of radiation'll do that to a guy. Think Pa Kent, but without the wrinkles and
a full head of mostly gray hair.

He'll also have a new secret identity. Very soon, the Megatokyo Tribune will
acquire a new reporter by the name of Kent Clarkson. ^_-

 I would strongly urge you to rethink this a little.  Having Luthor kill 
 everyone just out of sheer bloodymindedness doesn't make much sense.  
 Genom's style of domination isn't something the average Superhero would 
 fight very well against, and I don't see Luthor embarking on a total 
 slaughter without reason.  For one thing, it puts him at far too much 
 risk.  I mean, hell, why even bother with Aquaman?  That would just get 
 a very angry kingdom of Atlantis hunting for the man responsible for the 
 death of their king.

Aquaman dies because he's in JLA, and they are like, the highest members on
Luthors hitlist. He might not (probably won't, actually) kill ALL the others,
but the Justice League MUST die. Plus, when the hell does Quincy ever go
underwater?
  

 There's really no reason superheroes can't still exist, it's just that 
 Luthor did the sensible thing and came to Japan to avoid them (easily 
 getting the relativelty few Japanese heroes out of the way.)  I would 
 suggest Captain Marvel or the Flash and some others might still be 
 around.  Basically anyone who doesn't have the detective skills to track 
 down Luthor or isn't likely to conflict with him in the natural course 
 of events.

Coming to Japan wouldn't do all that much good. I mean, Megatokyo is subjected
to huge, menacing, only-a-superhero-can-handle-it kinda things all the time.
The Kanto earthquake, for example, would have attracted hordes. And Genom is a
multinational corporation: Eventually, one of the metahumans would take it
into his head to go to the source. 

The only conceivable time that superheros wouldn't bother with Japan is after
the Sabers showed up. They would be recognized as superheros by other
superheros almost immediatly, and they try to avoid each others turf unless
invited.

 I would also suggest that he only _thinks_ he's killed Batman.  Batman 
 is just as smart as Luthor.

As before, Batman is in the JLA, and therefor must die. It's pretty
ignominious, too; a sniper guns down Bruce Wayne at a public appearence. His
identity comes out after his death. Nightwing sees to his burial. Robin's
secret identitiy remains uncomprised.

Nightwing himself lives until the early 2020's, when the first Boomer rampages
in Mega-Gotham prove too much for him to handle. As of 2034, only Tim (Robin)
is still around, and he spends most of his time drunk into stupor and staring
at the monuments in the Batcave. He's not quite right in the head either. In
fact, it will be either him or Jimmy Olson who brings Supes up to speed on
what he's missed. 
  

 Having Luthor suddenly able to kill every single superhero in the world 
 when a thousand other genius supervillains couldn't handle even one 
 totally blows my suspension of disbelief here. (I know you can come up 
 with a thousand plausible scenarios, but it just isn't possible within 
 the framework of the DC universe.  It just couldn't happen that way.)

I'll have to reluctantly concur. He only kills the Justice League right away;
the others die later, whether of old age, retirement, or they started to make
to much of a nuisance of themselves.
  

 Besides, I'd really like to hear Luthor's plan for getting rid of the 
 Spectre.  "Well I'll just kill him.  Oh damn, he's already dead.  And 
 omnipotent to boot."

Admittedly, I know very little about Spectre. However, he doesn't appear to
intervene directly and personally all that often; he advises, and shows
consequences. The biggest thing he ever did, in my recollection, was help hold
the universe together during the whole Amalgam thing, and then he still wasn't
personally involved in the hero's lives.
 

 Oh yeah, and if you still have Wonder Woman dead, take out the rape bit. 
  I know you want to establish Luthor as a bad-ass, but I can't picture 
 him ordering that.  Not against someone with whom he has no personal 
 malice.  He isn't that sort of evil.

Actually, the rape bit was a joke. that isn't going to happen.
 

"When writing Superman, think what Batman would do in the same situation.
Then write the exact opposite." 

 
 I would say that's more true for personality traits.  Sometimes their 
 means will differ, but not totally.  Batman will intimidate, but like 
 Superman, he won't kill.

That's what I meant. And they ARE pretty different, method-wise; I've never
seen Supes resort to the kinds of interrogation Batman does. Plus, Batman
depends a lot more on finesse and less on brute force.
