Green Lantern: Emerald Knights is a 2011 American animated superhero film that tells various stories featuring members of Green Lantern Corps, including Abin Sur, Laira, Kilowog, and Mogo. It was released on June 7, 2011. While not a direct sequel to First Flight, the film uses the same character designs and includes a cameo by Ch'p, who had a speaking role in the previous film.
It is the eleventh film released under the DC Universe Animated Original Movies banner. It is also the second DC Animated Movie following Batman: Gotham Knight to feature an anthology format, though unlike the latter, it features a single, uniform animation and visual style and an overall linking story. Animation was outsourced to Studio 4°C, JM Animation and Studio Pierrot. The film received mixed-to-positive reviews with many critics praising the animation, voice acting, and action sequences, but criticizing the story and characterization.
Two of the stories ("Mogo Doesn't Socialize" and "Abin Sur") were based on comic stories written by Alan Moore, who has a standing policy of not allowing his name to be used in the credits when his stories are adapted to other media. Although it uses the same name, it has no relation with the 1998 comic book Emerald Knights.
Despite the film featuring a standalone story, Nathan Fillion would later reprise the Green Lantern role in several DC films, particularly the DC Animated Movie Universe.
Plot
The sun of the Green Lantern Corps' homeworld, Oa, is becoming a gateway for an anti-matter entity called Krona. In response, the Guardians of the Universe start evacuating Oa of all valuables, such as the Central Battery. While in line to charge their power rings before the Battery is removed, new recruit Arisia Rrab admits she lacks faith in her abilities. Hearing this, Hal Jordan tells her the story of the first Green Lantern.
Green Lantern
Avra, the Guardians' humble scribe, was chosen by one of the Corps' first four power rings despite not being a warrior. He, G'Hu, Wachet and Blu are tasked with stopping the Dominators, but Blu is killed in battle. Nonetheless, Avra uses his imagination to create the first ring construct and lead his allies in destroying the Dominator fleet. Ever since, the power to shape constructs from the power rings becomes standard operating procedure. After his death, Avra's ring is passed down through the years, eventually coming into Abin Sur and Jordan's possession.
In the present, Jordan and Arisia meet Kilowog, the Green Lantern Corps' head drill sergeant. Jordan tells her not to fear Kilowog and recounts the story of Kilowog's own trainer.
Kilowog
Sergeant Deegan trained the rookie Kilowog, among others, by removing their power rings and putting them into deadly situations. An angry Kilowog accused Deegan of not valuing his trainees' lives before they and the recruits were called to defend a nearby planet from the Khunds. Deegan abandoned Kilowog to lead the other recruits, ordering them to protect the refugees while he fought the invaders. Once Kilowog caught up, Deegan had been mortally wounded. Before he died, the latter revealed he was doing what was best for the rookies and passed his authority to Kilowog, who completed the mission.
Jordan and Arisia arrive at a border patrol at the sun to await Krona's return, where they hear a prophecy from Laira, whereupon Jordan shares Laira's story.
Laira
For her first solo mission, Laira was sent back to her homeworld, Jayd, to address war crimes committed by her people. After learning they were ordered by her father, who was driven into rage and jealousy after her ring chose her instead of him, she eventually defeated him in combat, after which he admitted she had truly become an adult before committing ritual suicide to maintain his honor. He died in a tearful Laira's arms, claiming that she was Jayd's true protector, not him.
Back at the border patrol, every Lantern extant are called to await Krona's return, with the apparent exception of Mogo. When Arisia asks who Mogo is, Jordan explains.
Mogo Doesn't Socialize
The warmonger Bolphunga sought to fight and kill the universe's most powerful warriors. After his latest opponent tells him he will never defeat Mogo, Bolphunga traveled to a mysterious planet in search of him. He spent weeks tracking a plethora of powerful energy signatures, but his search proved fruitless and he planted explosives to flush out Mogo. However, Bolphunga soon discovered Mogo is the planet itself as the latter extinguished the bombs and captured him before he can escape.
