Infinite Crisis or Crisis (with inspiration from All-Star Superman). Assuming Darkseid doesn't bite it at the end of JL2, he attacks Earth again full force and he is in no mood for taking prisoners, this is personal for him and destroying the league at any cost is his goal. Darkseid initiates several failsafes to take down Earth and it's heroes and each task demonstrates how much each Leaguer has grown since we first met them. However, each of Darkseid's tasks prove too much for the leaguers and they lose a member with each task. Darkseid is winning. Superman is the last member to be standing, heavily weakened and poisoned from the tasks and emotional stress of losing his friends. the universe shall end how it began, with Superman. Superman and Darkseid face off one last time as Darkseid reveals his last failsaif, the destruction of Earth's sun. Superman sends Darkseid to the phantom zone, where he will never be able to escape, as the rock faced warlord taunts Superman one last time. Superman looks at the increasingly unstable sun and knows what he has to do. "I not letting anymore die because of me." he flies into the sun after giving Lois a final goodbye, restoring it with the solar energy stored within him. The League is not forgotten, they become the modern world's legends, earning their place in the universe's mythology. As the movie comes to a close, we see the outlines of others. Newer, younger heroes, inspired to do good. As the heroes leap off, the film ends on a final shot of the league, in their classic poses from the JL cartoon.

I'm very tired...
