The issue starts of right where #6 left off with the heroes gathered around Superboy. The heroes get word via Green Lantern’s (Hal) ring that the villains are attacking Metropolis because if they can take out Superman’s city then they can take over the world. During the fight Judo Master gets his back broken by Bane and Black Adam rips Amazo’s head off. Just as Doomsday is about to go after Arsenal Superman and Kal-L show up and take the fight to him, along with the other heroes showing up to fight the villains. Just as Kal-L starts to confront Alex, SBP shows up and knocks him away and says he wants nothing to do with this Earth. SBP grabs Wonder Girl whom is then saved by Bart – an older Bart- in Barry’s old Flash costume saying that it was the only costume that could survive the trip. SBP then heads off to OA to destroy the planet and create a new Big Bang that only he could survive and upon leaving shoots a hole in Breach’s outfit causing a reaction that returns Captain Atom to the DCU. Down on the ground Alex shoots Nightwing with a blast in the chest which “appears” to kill him. Out in space SBP fights his way threw the Green Lantern Corp killing a number of them only to have Superman and Kal-L show up and take him away. Cut back to Earth and you see Batman knock Alex down and grab a gun. Just as he is about to shoot him Wonder Woman shows up and tells Bruce that it’s not worth it so he tosses the gun aside. Back in space you see Superman and Kal-L flying through a Red Sun with SBP and crash into the planet Green Lantern. SBP continues to beat on Kal-L when the rest of the Corp shows up to capture SBP. At that point Kal-L dies. We then get a panel where you see Metropolis pretty well damages but the heroes won – how we don’t know as that fight wasn’t covered too much and a one shot of just that fight should have accompanied IC#7. The heroes in space have still not returned. A kid on a beach finds the Tangent Universe’s Green Lantern’s staff. Bart hands over Barry’s costume to Jay as Bart has now exhausted the last of the Speed Force. You then cut to Gotham where you see Alex who gets attacked and killed by the Joker as Luthor looks on telling him that “you made a lot of mistakes. You underestimated Superman. Superboy. Me. But the biggest one is that you didn’t let the Joker play”. At the Gotham docks you see Diana, Clark and Bruce all make amends and take off in their different directions to find themselves; Bruce is with Dick and Tim. You then cut to OA where you find out that SBP is being held in a containment field surrounded by a junior Red Sun eater and 50 Green Lanterns watching him at all times. SBP then carves the Superman symbol into him chest saying “I’ve been in worse places than this. And I’ve gotten out.”
Because, unlike a lot of DC villains, he is a legitimate physical threat to not only the top tier characters in DC but also to entire teams of said characters. Besides if they killed him off they'd just have to come up with an explanation on how he was resurrected the next time they wanted to use him.

So, nothing about Pariah??
Even though Alex Luthor knew Pariah is immortal and indestructible he tried to kill him by shooting him (he knew Pariah survived collapsing Universes and everything else thrown at him, yet tried to kill him with a gun, what was that about?). I always expected him to at least show p sometime during the rest of the Crisis.
