Fan Casting Justice League Death's End

When Batman and his team get back to the present thanks to past Flash's speed, they confront Lex but right then and there hes killed by Darkseid and the world falls into chaos and Batman, Past Superman, Wonder Woman, Aquaman, and Shazam, all make it onto Darkseid's ship and start taking out parademons until they find a room on the ship with a cosmic treadmill built by Orion. Batman tells Superman to use it and when he does a portal opens and Wally West is freed from the dark Speedforce. Now the team is ready, but Batman tells flash to get everyone but him and Superman off the ship because it's too dangerous, of course Flash doesn't agree with it but does it anyway. Batman rushes into the control room with Superman but Darkseid enters the room so Batman pushes Superman off the ship and he flies the ship away into space and into the sun and since Apocalypse is a hivemind when Darkseid dies all of his forces on Earth die too. At the end of the movie everyone is at Bruce's funeral and Richard Gray leaves the role of Nightwing behind to become the new Batman and have Jason Todd as his Robin. In the post credits you see Jason Todd's Robin become the new leader of the Titans and renames it to The Teen Titans but now Slade is ready to destroy Richard Gray.
