HBO Officially Changes a Fundamental Rule of DC Superhero Canon

In the 2014 animated film "Justice League: War," HBO officially changed a fundamental rule of DC Superhero canon regarding Green Lantern's powers. During their initial encounter, Batman demonstrates that he can easily remove Hal Jordan's Green Lantern ring, which immediately depowers him and removes his costume. Hal regains his abilities only by re-summoning the ring to his hand. This significant alteration to established lore reveals a vulnerability for Green Lanterns, suggesting their powers are not inherently tied to them but directly to the physical possession of the ring, making them susceptible to being disarmed.
