10 Shocking Comics Events That Changed Characters Forever
5. The Creation Of The Sinestro Corps - Green Lantern #10
For the longest time, Sinestro's whole thing was just being a rogue Green Lantern that went bad. But then - like so much else with the Green Lantern mythos in recent decades - along came Geoff Johns.
His original 2006 run introduced the idea of the color spectrum of power rings, with one in particular causing some major problems for the Corps - The Sinestro Corps.
Realizing that destroying an entire planet full of super-powered space cops on his own wasn't quite working out for him, Sinestro decided to send out yellow power rings across the cosmos and build his own army, with blackjack and hookers.
considering how far the Green Lantern mythos - Geoff Johns in particular - will go to bend over backwards to stay exactly the same as it was in the sixties, this was a massive shift in the cosmic power dynamic between Hal and his arch nemesis. Sinestro was no longer just some rogue agent, he was the leader of an entire army, and had the resources to really make the Corps hurt.
