Watch Green Lantern: Emerald Knights

Green Lantern: Emerald Knights is an animated anthology film. As Krona, a tyrannical alien consisting of anti-matter, attempts to convert the sun of Oa, the homeworld of the Green Lantern Corps, into a gateway, the Guardians decide to ditch anything valuable on the planet--including the Central Battery from which all Green Lanterns draw power from. As the entire Corps lines up for a final recharge, Earth's Green Lantern, Hal Jordan talks to newcomer Arisia in order to calm her worries. It is through Hal's conversations with Arisia that the five featured stories come about.

The particular stories which Hal tells Arisia, and the film showcases, include the story of the very first Green Lantern, the back-story of the Corps' sergeant-at-arms, Kilowog; the duty of Laira; the story behind how a planet, Mogo, could possibly become a Green Lantern, let alone achieve sentience; and concluding with the tale of Abin Sur, Hal's predecessor, during the prime of his service to the Corps.

The film cuts back to Hal and Arisia with Krona making his appearance, attacking the entire collective of Lanterns. Despite her inexperience, Arisia figures out how to stop Krona, for which she is commended during the move to Mogo.
