18. Hal Jordan

(Green Lantern/Justice League of America, DC Comics)

Look, Hal Jordan is a decent character, but there's no reason for him to still be around. So when he went crazy, killed the other Green Lanterns, and started calling himself Parallax, it was a natural reason to write him out.

Unfortunately, they took forever to actually do that. But during Final Night – when the Sun-Eater devoured Earth's sun and doomed everyone to a slow, horrible death – Hal had a moderate change of heart and decided to go reignite the sun, killing himself. In death, he would eventually fuse his soul to The Spectre to stop God's angel of vengeance from throwing an "I'm so lonely" temper tantrum.

Years later, he came back to life, and it was revealed that Hal hadn’t turned evil and crazy. No, he was possessed by a giant evil Space Bug named Parallax who made him do all those things.

Good to know!
