So if I understand this correctly, those stupid Monitor guys want to eliminate Kyle Rayner, Donna Troy, and Jason Todd because they're anomalies, or something like that. It seems like a more sophisticated response would be to find a way to help them fit (assuming they need help, all three of them seem to be doing okay, except for the attempts on their lives) into the brand spanking new Multiverse (is it new? Or is it only new to us, and to everyone else this is how it's always been?), rather than just killing them and potentially incurring the wrath of the other heroes.
But what do I know? I'm not some big, pink idiot in stupid armor, running around deciding who fits and who doesn't. That being the case, I guess Donna, Kyle, and Jason better get to running for their lives. My suggestion would be that they try to find that magical "Haney-Earth", that so many fans hope is out there, somewhere amongst the 52.
It'd be the perfect place to hang out. The Montiors are such sticklers for everything fitting together, and being in its proper place, their heads would explode at the insanity of Haney-Earth.
And who knows, it might just be a nice place for them to sort things out. Jason Todd would magically stop being angry and homicidal. Donna Troy wouldn't have a confusing origin anymore. Which isn't to say her origin would be static, it
would keep changing, but each new origin would remain totally separate and unconnected from the previous ones, and would fit perfectly with whatever situation she found herself in at the moment. And Kyle? Well, Kyle would probably continue about as usual. He strikes me as capable of being totally oblivious to all sorts of odd goings-on.
