Adorkable : Before her Face–Heel Turn, and a little bit when she becomes good again, Aya is prone to acting like a naive, excitable little girl. She takes in everything with an adorable curiosity due to her unfamiliarity with the world. Combine that with her nice and altruistic personality, she's downright Moe.
Alas, Poor Scrappy: LANOS, after he goes into warp and takes Anti-Monitor Aya with him. Even Hal seems sorry for him.
Hal and Kilowog in "Reboot". Their hostility against LANOS begins immediately, without context, and they're willing to replace his AI with Aya's when the latter is to be dissected. This winds up as a Double Standard since it sends the message that it's okay to trade one sapient entity for another so long as the other is a Replacement Scrappy. Word of God says that his level of sentience is lower than Aya's.Later revelations confirm that Aya was unique in her kind and LANOS couldn't grow like she did.
Is Guy's eagerness to show off and one-up Hal simply because he's just so full of himself and pleased to see Hal ticked off or with the consideration of his Hidden Depths is he merely doing it because he wants to prove himself as the latter's equal? For all Guy Gardner does, he only ever seems to antagonize Hal with words and is quick to team up with him and back him up whenever he is needed (and always without the latter's explicit request). In fact, Hal is the one who initiates all of their fights with Guy only reacting in response to Hal's hostility.
Anti-Climax Boss: After the Anti-Monitor being built up as a genocidal, universe-crushing, unstoppable Big Bad from the moment he appeared onscreen, he's killed by a super-charged, emotionless Aya in a matter of seconds before she hijacks his body and takes over as Big Bad of the season.
Awesome Music: The soundtrack overall is gorgeous, and the title theme sure makes for its short run time with a triumphant fanfare.
Broken Base: The relationship between Aya and Razer. Is it a moving romance that became one of the best parts of the show, or a creepy Romantic Plot Tumor that was ultimately pointless thanks to Aya's seeming death in the finale?
The Anti-Monitor, the Big Bad of the second arc until Aya takes over, is a machine obsessed with nothing less than the obliteration of everything in the universe that isn't himself. Built to be a knowledge-gathering robot, the Anti-Monitor quickly realized his superiority to all life in the cosmos, and was banished to another dimension soon after his proclamation to destroy everything in his path. The Anti-Monitor proceeded to turn trillions of planets in this alternate dimension into antimatter which he then consumed to make himself stronger, and, though making a deal with the last remaining planet's population to not consume them should they build him a portal back to his own dimension, the Anti-Monitor drained their sun of nearly all its life before he left, ensuring that the planet would still die soon after he was gone. Once back in his home dimension, the Anti-Monitor reactivates the Manhunter robots across the universe and orders them to kill everything they see, and, when confronted by Hal Jordan, the Anti-Monitor tries to force him to watch as first his friends, then entire worlds, are consumed before him. Even when beaten, the Anti-Monitor desperately tries to strike a deal with Aya to assist her in her plans to destroy reality itself to save his own hide. A megalomaniac who couldn't stand anything living except himself, the Anti-Monitor's narcissism was only matched by his petty sadism.
"Razer's Edge": Myglom is a seemingly moral warden of a Green Lantern prison, but is in actuality a sadist who masks his villainy as a "rehabilitation program". Myglom subjects dozens of prisoners to a machine that makes them relive their worst memories over and over again before webbing them up to be devoured at his leisure. When Hal Jordan and Kilowog deliver the Red Lantern Razer to Myglom's prison, Myglom subjects Razer to the same torments of his other prisoners, and when Hal and Kilowog realize Myglom's villainy, he captures them and plans to eat them alive after using his nightmarish machine on them.
"Heir Apparent" and "Regime Change": Prince Ragnar, brother of Queen Iolande, is an unfathomably petty, spiteful narcissist. Craving the power of a Lantern so as to rule his world, he poisoned his life-long mentor Dulok to get his Lantern ring and later tried to do the same to Kilowog, believing himself the only one worthy of its power, before attempting to slit his own sister's throat to ensure if he couldn't rule, neither could she. In his second appearance, Ragnar's rage earns him a place in the Red Lanterns ranks, taking over his world with them and waging war on any resistance. He would then have the Red Lantern Corps plant a "Liberator" on his world, intending to exterminate his own people of 2 billion lives, simply to spite them all for not wanting him as a ruler.
Even when his only appearance was a few seconds in a sizzle reel, fans adore Saint Walker. This became ever more apparent when he appeared in the show came off about seventeen times more badass then he's ever been in the comics while keeping his characterization completely intact.
Ch'p. Within seconds he proved himself capable of taking out Hal Jordan, despite said Lantern's greater experience and having gone toe-to-toe with Atrocitus. It also helps that he's a squirrel.
Razer is a Sad Rage Zebra Bunny. And on occasion, Space Zuko.
Saint Walker is Saint Flawless.
Hal is also called Papa Hal.
Kilowog's known as Kilodad. The name, like Hal's, comes from their protective parental stance towards Aya. Kilowog's hugs are known as Kilohugs.
Mogo is the GL Death Star as coined by the creators.
While not quite a nickname, Aya gain an Superhero Sobriquets as she is a piece of Ion, the entity that resides in the Green Lantern central battery, Fans have taken to calling her Aya, Daughter of Ion.
The Fandom itself is called the Green Fanterns, usually shortened to just Fanterns.
The thrill that the planet from the Steam universe feels when they see the stars again becomes this when the stars start going out in their new one too.
"Dark Matter" opens with a speech from Appa Ali Apsa giving a speech to the Green Lanterns, saying that these may be the very last orders he will give them due to the universe ending threat. In light of the series' cancellation, this provides a bit of Reality Subtext.
He's Just Hiding: It seems that many fans, like Razer, believe that Aya is still alive. An official drawing◊ of Razer as a Blue Lantern implies that Aya could have returned if the show had continued. This is confirmed by her appearance on Justice League Action.
Jason Spisak plays Razer in this show, and is part of the main team with Hal Jordan and Kilowog. In DC Super Hero Girls, he ends up playing both Hal Jordan and Kilowog.
An AI with a name derived from “AI” that is deemed a mistake by their creators, takes on a humanoid form, undergoes a Face–Heel Turn with the apparent intent of destroying life, and then sacrifices themselves to eliminate an army of Mecha-Mooks with copies of their personality, with their stoic, brooding, revenge-filled Implied Love Interest leaving to search for a sign they’re still alive. Am I talking about Aya in Green Lantern: The Animated Series, or Ai in Yu-Gi-Oh! VRAINS?
Ho Yay: In "Lost Planet", Drusa comments on the perfection of the curvy Aya and even gives a Male Gaze to her. She even pretends to twist her leg to have her carry her to the ship (granted she was just hacking into the ship but all the signs were there). Unofficially confirmed byWord of Ceiling Giancarlo.
Guy and Hal have this in spades. Their friendly rivalry can come off as this. They initially antagonize each other but it's quite easy for them to get along with the right circumstances. Once they realize they're on the same page and have a lot in common about their opinions of the Guardians, Guy immediately asks Hal if he likes chicken wings and they hang out on a rooftop. Oh, and Guy outright hugs Hal on live television without hesitation and doesn't even let go when he realizes they're being filmed.
There's also a moment when Guy pulls Hal out of harm's way despite the fact that he just insulted him earlier.
When Guy first sees Hal he thinks he's a fanboy.
Jerkass Woobie: Larfleeze. Yes, he is a greedy jerk, but you can't help but feel sorry for him when you see him bursting in tears, crying to get his "shiny" back. Becomes even sadder in perspective when you realize this guy once fought toe-to-toe with Atrocitus.
Just Here for Godzilla: A large amount of people only watched the show for Razaya, and the fanbase often ignore the other characters in favour of them. It isn't helped by the fact that they were the only ones to get any significant character development.
Like You Would Really Do It: On the one hand, they really did kill Aya. On the other hand, believing they won't undo that is a hard pill to swallow. It turns out she barely survived by performing a Body Surf into a disabled Manhunter. Unfortunately, things went downhill from there.
Magnificent Bastard: "Prisoner of Sinestro": Thaal Sinestro is a celebrated, but maverick Green Lantern known for his Nerves of Steel and willingness to bend the rules to suit his purposes, as well as being a friend and mentor to Hal Jordan. Tasked with recovering the dangerous assassin Neuroxis, Sinestro is imprisoned by his fellow Green Lanterns when he falls victim to Neuroxis's mind-jumping powers. Escaping with ease and deducing the criminal's abilities and weakness, Sinestro forms a plan to force Neuroxis to abandon its host in favor of returning to its own body, voiding the atmosphere on the Interceptor except for Neuroxis's prison cell, forcing the criminal to return to its own body or suffocate, stoically keeping to the plan even as Razer nearly suffocates. When the plan works, Sinestro reveals that he had depressurized the cell, coldly taunting Neuroxis as the creature painfully suffocates, covering up his actions and presenting the death as an accident, considering Neuroxis's death to be justice served.
Romantic Plot Tumor: For some fans, Razer and Aya's romance is one of the less enjoyable aspects of the show, as their focus begins to overshadow story arcs and villains that had more potential, including Aya completely destroying the Anti-Monitor. And especially during the second half of the second season, it can really start to feel like even Hal Jordan's been turned into a supporting character on his own show by one Canon Foreigner character and another character who'd barely been developed in canon, because their romantic drama begins to overshadow everyone else, whether it's Hal, Tomar-Re, Sinestro, or Larfleeze. What also doesn't help matters is that their story ends with no resolution, with Aya's seeming death and the show getting canceled.
Squick: Aya taking on the form of Razer's dead love and eventually starting a romance with him while still using it. She does it innocently, but it's still uncomfortable for some and is a contributing factor in their romance being polarizing.
Strawman Has a Point: Kilowog's arguments against Aya being a Green Lantern. While many of them boil down to "she's a machine" and cannot qualifynote he doesn't bring up the Guardians having a say in it, but then again the Guardians are the poster children for counterproductive, that and in the second half of the season, the Science Director tried to have her disassembled.. However, some points, like her assuming a robotic form and leaving most/all the systems of the ship, hold water, like when she left it to the cargo captain, who accidentally detached the cables she was using to tow a ship, and he could have flown it into the black hole. Also, when Razer caused an explosion/virus, she could not see what he was doing to the ship's systems from her form, and only used an optic to see what he was doing it was a fake out, but if it wasn't they'd be stranded right behind Shard.
The Anti-Monitor is widely regarded as one of the most powerful villains of the DC Universe, having wiped most of the multiverse in the mainstream and while he's presented as powerful and menacing... He's taken out by Aya, who takes over his body as the "Aya-Monitor" and when it turns out he's alive he gets his head smashed.
Tomar-Re could have become the Sixth Ranger of Hal's group, considering his role as a more by the book lantern and was more level headed than the others, instead he only appears in 3 episodes.
Additionally, when the whole Green Lantern Corps ends up fighting the Manhunters, we see neither Sinestro (who was in for one episode and that was it, we probably would have seen more had the series continued) nor Mogo (who had appeared before and probably was banned owing to Story-Breaker Power).
