Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

In Justice League, we got to know that Steppenwolf already tried his plan in the past; and the combined power of Amazons, Atlanteans and humans defeated them. But there were others involved too, some major DC characters, one Green Lantern (not sure which one), Zeus and someone with fire arrows and a few more. So who were these heroes with powers? Are they some DC comics characters? I can identify Zeus but not the rest. Who was the Green Lantern, that died, in that fight?
What were all the fighters in previous Age of Heroes?
