Apparently Harry Potter is ok to use in the next LOEG, but Before Watchmen is wrong. And before you start yelling, SATIRE! Keep in mind that Moore has always borrowed literary characters for use in his own work, it's the whole point of LOEG, he only changes the names when the characters aren't in the Public Domain. And unless I'm mistaken has never asked permission to use the characters he's borrowed in LOEG.
Can't wait to hear how Harry Potter's creator feels about this. If they are smart they'll probably ignore it.
One comment from the below article was particularly funny, "The electrons aren't even dry yet on him raging at HIS CHARACTERS." Another reads, "Didn't he do an interview saying that he was sick of his creations being messed with or as he put it RAPED, now he's doing the same with the whole Harry Potter deal."
