Worlds collide and many die. The villains that remain wish to exterminate the heroes to take the galaxy. The heroes that remain are all that stand in the way. All are Bloodlusted, no morals. The heroes understand that this is how it has to be done. Each hero and villain are at their most recent and alive* versions. The battlefield is the entire galaxy. However it starts on Earth. It happens in real time. No time off unless they can afford it. Battle is to the death.
