9. Final Night
Look, sometimes the sun just goes out because something ate it, and you just gotta deal.
Final Night really comes to be great in its tie-ins. The Flash and Hitman ones, in particular. Seriously, seeing the Noonan gang barricade the bar and decide that if the world's ending, they're just gonna drink until it does, is brilliant.
As the earth gets colder, winter storms sweep the nation, and the oceans freeze over. The Justice League panics, and tries to find a way to beat the Sun Eater (the thing eating the sun). They eventually figure out that they have to reignite the sun to blow the Sun Eater out of the solar system. However, whoever does it will probably be atomized in the nova explosion.
And who volunteers but Hal Jordan, aka Parallax. Hal does it to redeem himself after going all super crazy during Emerald Twilight. Hal dies in the event, and is mourned as a hero who totally didn't kill almost all of the galaxy's police force because he was mad at things.
Lasting Impact: Hal Jordan stays dead for a while. Also, although it doesn't happen DURING the event, it’s later revealed that Oliver Queen is brought back to life during Final Night.
