10 Unbelievable DC Plot Twists That Shocked The World
8. Hal Jordan Goes Insane, Kills Everybody, And Becomes Parallax
It can't be much fun being a Superhero. Oh sure, you get to rush around, saving the day, while having powers beyond your wildest dreams but somewhere down the line a catastrophic event is going to happen to you, turning you evil. And considering that most good guys have a tragic past to start with, you've got to wonder if villainy isn't the way to go.
This is the fate that Hal Jordan succumbs to during the Emerald Twilight storyline. When Cyborg Superman and Mongul use a series of bombs to destroy Coast City, Hal gets some closure by defeating Mongul, but it's not enough.
He attempts to remake his home with his Lantern's light but is stopped by one of Guardians who pays the ultimate price, when Hal squish's his tiny blue head. From here on out, it all goes downhill quite rapidly for the Green Lantern.
He set's out to take the ultimate power from its source and on the way, he wipes out the Green Lantern Corps, as well as the remaining Guardians when he finally immerses himself within the power battery.
Hal then spends a lot of his time terrorizing the DC Universe as the entity known as Parallax before sacrificing himself for the greater good, but it's that initial three-issue arc that is the most mind-blowing.
