HBO Officially Changes a Fundamental Rule of Green Lantern Canon

In HBO’s Lanterns, John Stewart (Aaron Pierre) spends his whole life preparing to become a Green Lantern. He seemingly abandons his destiny in episode 5, turning down the ring after becoming disillusioned with how the Guardians of the Universe treated the Manhunters and Hal Jordan (Kyle Chandler). John gets another chance to become a superhero in the season finale, but that power comes with a huge drawback tied to one of DC Comics’ greatest villains.
