ZERO HOUR #4

In the distant future, an unseen figure attacks the Time Trapper. In the present, a young and healthy Batgirl appears, but doesn’t recognize Robin. The Linear Men realize that the universe is ceasing to exist, from the end of time backwards and seek to help The Flash in the 64th century and Green Lantern, as Pol Manning, in 5700 AD stop it. Back in the present, Batman and Superman summon the superhero community, but Hawkman seems to splinter into many Hawkmen, as Waverider appears with Wally’s empty Flash costume. Meanwhile, at Vanishing Point, Extant has overcome the remaining Linear Men.
