10 Times Superheroes Did The Wrong Thing For The Right Reason
5. Hal Jordan And Zero Hour
Hal Jordan, possessed by the fear creature Parallax, planned to restart the universe to reflect his own views. Hal wanted to eliminate all evil and resurrect his destroyed hometown, Coast City. Parallax fought the heroes, was weakened by the Spectre, and killed by the Green Arrow. A new Big Bang happened and repaired time through natural means instead of a guided hand.
Hal tried to recreate Coast City with his ring. This was a violation of Corps rules and it got him called to OA to be reprimanded. But the devastated Jordan left many of his fellow Lanterns for dead as he took their rings. Hal murdered the Guardians and took the power from the Central Power Battery. This made him an easy target for the Parallax entity that had been trapped within.
The DC Universe needed to be fixed. The Crisis on Infinite Earths took more than 50 years of stories and tried to distill everything down into a single cohesive history on one planet Earth. But things fell through the cracks. The histories of a few characters refused to be retconned. So writers and artists tried on their own to fix it with varying degrees of success.
