It was Vibe and Steel who didn’t live on to see the new Justice League. Although Gypsy and Vixen didn’t make the cut, they were at least still alive.
Now for 2 Truths/1 Lie. The Year is 1988:
Batman: The Killing Joke was released. Not only did it give a more detailed origin for The Joker than ever before, it also changed the life of Barbara Gordan when The Joker shot her and paralyzed her.
Keeping with the annual crossovers that started with Crisis on Infinite Earths, DC published Millennium. In this event, the Manhunters, Space’s Police Force before the Green Lantern Corp, set their sights on Earth. They planted spies (both volunteered and mind controlled) amongst Earth’s citizens, including Superman’s Smallville best friend, Pete Ross, and Flash’s Father, Rudolph West. In the end, Earth’s Heroes prevailed with help from the New Gaurdians.
Jason Todd’s life hung in the balance as readers voted on if he would survived the A Death In The Family storyline. He didn’t. He was beat to death by The Joker with a crowbar and then the building blew up. This became Batman’s greatest failure and haunted him for years.
