I thought Final Night was a candidate, that is why I bought the four single issues at Comixology.
I am certain that regular Hal Jordan is on the final page.
That means after Parallex, after him being Spectre.
It felt like a prologue issue.
I don’t know if it was the same series, but I also have a vague recollection of Metropolis being under attack, and a line of defenders that was not the usual A group of super heroes, like Cops, Firemen, Super Villains and C and D type Super Heroes.
Along with that, I see the big guns finally appearing, and Wonder Woman thanking Frankenstein for holding the line. They both might be attacking and using swords.
I bought Last Will and Testament when it came out but don’t remember it tying into anything. I thought it was just a one-shot for the sake of a one-shot.
