what happend in jsa?
the nail and another nail showed the exsistence of a multiverse...
i wonder if the nail universe had a coie?
Justice League: The Nail II was the Nail multiverse's COIE.
The story started off showing the war between the Green Lantern Corps and Apokolips. At the end Apokolips was destroyed and Darkseid was dead. Although, there was a mystery. Just before Darkseid died, he yelled out that he was the only one able to save the universe. It turned out the reason he yelled that was because he alone could sense IT aka The Limbo Cell. It merely ate anergy and was content. That felling of contentment was what alerted Darkseid to its presence and he started working on ways to destroy it. One of them was a modified Amazo android. The heroes were scrambling around trying to figure out what exactly Darkseid was referring to and then try to save the universe.
The Limbo Cell was draining energy from across the multiverse. Black Canary, Star Sapphire, Power Girl, and some other metas stole the Amazo android(laced with Apokoliptian tech) from Doctor Magnus which Dinah was hoping to save Olliver Queen's life. Ollie's mind was put into the Amazo andrioid and he sacrficed himself to stop the Limbo Cell. If the Libo Cell wasn't stopped, the multiverse would have reached a critical condition and all of space and time would happen at once and eventually collapse.
Joker ws dead and in Hell. He was taking advantage of the situation by psycologically torturing Batman and then trying to drag Selina Kyle bodily into Hell. Batman shoved Selina away and pushed the Demon Joker back into the portal to Hell, even though he would be trapped in Hell. The ghosts/angels of Dick Grayson and Barbra Gordon stepped in and sent Batman back. At the end, we had a smiling Batman who looked like he would eventually marry Selina Kyle. Batman and Catwoman asked to join the Justice League of America(in Batman's case, rejoin). The JLofA accepted the two of them with open arms. Star Sapphire also joined the JLofA as well.
The Nail multiverse walked away from their COIE pretty much intact. The few deaths that were recorded had meaning and wasn't stuck in the revolving door.
