When Lex Luthors Level 33.1 project, which is studying and using people with super-powers as weapons, comes to fruition, Oliver Queen brings together several heroic super-powered allies together: Arthur Curry, Bart Allen, and Victor Stone. Bart has been breaking into LuthorCorp facilities and downloading files. As a result, Lionel Luthor meets Lex and tells him that another LuthorCorp facility has been hit. Lionel says six facilities have been attacked, all having to do with 33.1. Lex is not worried and shows Lionel a security camera photograph of a red blur. Lex says that whoever is responsible can move very fast and he intends to catch them and make them a test subject. Chloe Sullivan reveals that she knows Oliver is the Green Arrow; Clark Kent admits that Bart can super speed. He says Bart is in some kind of trouble and asks her if they can track his cell phone. They look up his records and realize that Bart is working for Oliver Queen. Meanwhile, Bart is at his next assignment, but is caught by an electrical trap and knocked unconscious. Lex arrives immediately to take possession of him. The next day, Clark confronts Oliver about Bart. Clark thinks Oliver is using Bart to fuel his vendetta against Lex. They argue because Oliver says that Clark is waiting for trouble to show up at his doorstep. Oliver explains to Clark about 33.1, and says his team is working on it as Arthur Curry and Victor Stone arrive. Oliver is working to stop Lex from using 33.1 to build an army of super-powered meteor freaks, and eventually starting a war. Clark concedes and asks for more information. Oliver knows Lex has Bart, and his team is already on it. Meanwhile, Bart wakes up in a cell and Lex wants to know who he's working for. When Bart does not answer, but retorts, Lex activates the pressure plates in his cell: if Bart does not keep moving he will be intensely electrocuted. Oliver and his team work to locate Bart and narrowed it down to 100 miles. Clark suggests they get help, and he goes to Chloe. She gets a lead and Clark tells her to get the information to Oliver while Chloe goes to Queen Tower and gives Oliver the lead on Bart. Oliver pulls up a schematic of the building and Chloe notices several rooms lined with lead. They prepare to move out to check the facility and Chloe realizes that the facility is also being used to store meteor rocks. Clark enters the lead-lined vault containing refined meteor rock, and collapses. Green Arrow knocks two guards unconscious, and then the team enters while Chloe coordinates from his "Watchtower." Victor interfaces with the alarm system and Arthur enters from the harbor entrance. Green Arrow and Cyborg go in on foot, then Cyborg goes off on a separate mission, while in his cell Bart begins to slow down form exhaustion. Each of them individually take out the guards, with Green Arrow knocking the one unconscious who has found Clark. Green Arrow sends him to get Bart then heads off, planting explosives. Cyborg and Aquaman meet up and Cyborg interfaces with the main computer. Clark gets Bart out just in time while Lex arrives to order a lockdown. Bart is so exhausted that his nose is bleeding, and he can't use his super-speed. Green Arrow confronts him and warns that he has ten minutes to get everyone out before the place blows. He then shoots an arrow at Lex, barely cutting his cheek, also scaring him. Chloe confirms that everyone has left the building and even Clark agrees to blow up the facility. They get out and Green Arrow triggers the charges, destroying the facility. The team meets with Clark and Chloe in his barn. Oliver reports that Lex is setting up laboratories all over the globe and asks Clark to join the team. Clark says he wants to, but he has to clean up his own mess first - meaning he has to capture all of the Zoners still out of the Phantom Zone. The members left Clark behind to go across the world to find more divisions of Lex's Level 33.1 project and stop his other illegal plans. Oliver shakes Clark's hand, then Oliver and his young justice team leave for their next mission, proudly saying, "Come on boys, let's go save the world."
When Green Arrow's band of heroes thwarts his efforts once too often, Lex employs a super-powered vigilante Black Canary to take down the Emerald Archer. Chloe is working late at the Daily Planet using the computers to intercept a file, as a masked figure watches her from the shadows. As she burns it to disc, the figure throws a knife at her and Chloe runs outside, letting the person she's in contact know she's in danger. Chloe gets to the roof where the figure attacks her: a blond woman in black with a black band of makeup across her eyes. She draws a knife on Chloe, but Green Arrow arrives and pins her to the wall. She pulls free and as Green Arrow fires three arrows, the woman deflects them with a sonic blast. She then knocks down Chloe and takes the disc, jumps off the roof, and breaks her fall with a cable. Clark talks to Chloe as she looks through files on female criminals and talks about how he's uncomfortable with the fact that Lana Lang expressed her love for his phantom duplicate. Noticing her injury, Clark finally gets her to admit she's doing freelance work for Oliver Queen. Clark goes to confront Oliver, angry that he put Chloe in danger. Oliver denies putting her at risk and notes they were hacking into Lex's projects. Meanwhile, the woman meets with Lex and turns over the disc, and he offers to pay her to bring him Green Arrow. Lex made Dinah believe that The Justice League were terrorists. So she breaks into Chloe's desk and checks her phone call log, finding Oliver Queen's number. After deducing his identity, she arrives at Oliver's balcony and shatters the window with her "sonic scream." Oliver is knocked out. Oliver is held hostage and accused of being a terrorist. He denies it but she calls Lex and has him initiate the wire transfer. Meanwhile, Clarks meets Chloe at the Planet, who realized that someone tapped into her activities at the Planet, from inside the Planet. Dinah Lance was the only one logged on and Chloe alters her photo to confirm she's the woman, who they nickname "Black Canary." Chloe locates the wire transfer and cuts it off. Black Canary goes to see Lex only for Clark to intercept her. Clark insists Oliver is not the villain but when she attacks him she is bounces off. However, when she uses her sonic scream it overloads Clark's super-hearing, knocking him down long enough for her to escape. After a confrontation with Clark she began to have doubts about Lex. Canary goes to see Lex and demands evidence about Green Arrow's supposed criminal activities. When she refuses, Lex shoots her but Green Arrow arrives and the two men fight. Black Canary arrives and takes out a guard, but as all three heroes shoot at each other, Clark arrives and deflects the bullets and arrows, then gets Black Canary away and lets Lex takes Black Canary's knife blade in the shoulder. Green Arrow walks out, wishing Lex better luck next time. Black Canary has set up a meeting with Clark and Oliver to apologize and retire from crime fighting. Oliver suggests it would be a waste and she should join up with his team. Clark again defers on joining up and Oliver strolls away with Dinah.
The Justice League are shown attacking Tess Mercer's headquarters for the search of Lex Luthor in the Arctic, after cleaning out the camp, they come across a dead end when they find Clark's signature red jacket and nothing else. The team then head to the Isis Foundation to use Lana's computers to try and find out information about Lex's disappearance but come up with nothing, and almost give up, but Oliver convinces them that Clark would never stop looking for them. Dinah says that for the four weeks they have been searching they have found nothing, with Impulse and Cyborg searching the southern hemisphere. However, Lex's teams have kidnapped Chloe roughly a month ago also, and are pretending to be the DDS and try to make her track down a group of "terrorists", who are, unknown to Chloe, actually the Justice League. She uses her new power to track down Black Canary and Aquaman via cellphone, and is about to get Oliver but recognizes his phone number and realizes who the "terrorists" are and discovers what she's done. Despite Chloe refusing to give Oliver's number to track him down, Black Canary and Aquaman are both captured, leaving Oliver the only one left. This is unknown to Oliver however, and he has managed to track down Clark to a shady Russian work camp, and together they break out, but it is revealed that Clark is powerless due to the Orb. On a plane home, they realize that the rest of the League has been captured, however they work out that Chloe is being held in Montana, at a LuthorCorp Facility named Black Creek. Together, Clark and Green Arrow break in the facility and split up in order to find Chloe.

The Justice League then meet at night in Metropolis and come to the conclusion, due to the fact that half the members have had their identities have been exposed, that they should disband for a while and go underground. Oliver, however, whose identity remains a secret, decides to stay in Metropolis. He soon discovers that Lionel was responsible for the death of his parents, which caused him to completely abandon his heroic persona. After several weeks, Clark confronts Oliver about his recent life choices and asks him for help to hide his identity by disguising himself as the red-blue blur. While in disguise, Oliver saves Jimmy Olsen from being kidnapped. This reminds Oliver of what its like to be a hero and decides to restart the Justice League.

Clark asked for help by Bart and Dinah to get rid of Doomsday once and for all by burying him under a Geothermal LuthorCorp facility. Clark gave Bart Black kryptonite and told him that he was going to split Davis from Doomsday and then bury Doomsday. Oliver crashed the meeting and told Clark they need to kill Doomsday but Clark said no and told Bart and Dinah about Oliver killing Lex. Bart and Dinah sided with Oliver and betrayed Clark and when they captured Chloe and Davis, Clark arrived where Green Arrow shot a kryptonite dart in his back so that he wouldn't be able to stop them. They took Davis and Chloe to the Geothermal facility and planned to bury Davis down there but he began to transform uncontrollably when Chloe used Black kryptonite to separate the two beings. Doomsday then wreaked mayhem on Metropolis where Clark arrived after Jimmy found him and removed the dart and also learned his secret. Clark located Doomsday and after a brief tussle between the two, brought him back to the facility crashing into it where the Justice League blew the tunnel trapping Doomsday. After the team attended Jimmy's funeral after Davis killed him, they went missing leaving Chloe in her new Heroes base, "The Watchtower" and Clark who has given up hope on humanity declaring that Clark Kent is dead.
After Chloe tracked down all of the scattered Justice League members, they realized that they needed to bring Oliver back from his own personal demons and arranged to play a game that would bring the hero of Oliver from within. They hired Victoria Sinclair as the face of the game and kidnapped Oliver from a casino owned by Victoria aka Roulette and imprisoned Oliver in a casket. It's later revealed that Black Canary shattered the window in the warehouse, Impulse saved Oliver from the truck and Cyborg hacked into Oliver's bank account to "rob" him as Watchtower was watching the whole thing. At the end of the game Oliver once again became the Green Arrow telling The Blur that he will be there to help.
Oliver, Chloe, and Clark discovered that their identities were at risk when they learned of an older organization of heroes known as the Justice Society of America. When they realized that the Society's members where being killed one by one by the villain, the Icicle, they made an alliance with the Society. Unfortunately, the alliance was strained by the fact that Oliver and the JSA's leader Carter Hall aka Hawkman, did not get along. Together, they managed to defeat the Icicle and John Jones even managed to get his powers back. The Society taught Chloe and Oliver the fact that they shouldn't act only as a team but as a family, which Oliver took to heart, inviting Chloe and John to go get something to eat after they had won their battle. Oliver was captured by Tess Mercer where he was introduced to Checkmate leader Amanda Waller who asked him to join Checkmate. Clark and Chloe talk about Green Arrow and talks about him not following protocols where the JL members plug in to Watchtower when the go on Patrol which he did not know about. He later escaped and went to Watchtower and they talk about Checkmate. Soon after, John secretly tried to investigate the agency known as Checkmate. Unfortunately his investigation pit him against Clark who found his motives suspicious. Unwilling to deal with Clark at the moment, John flew off. He then used his powers to read the mind of an agent of Checkmate to find the location of their headquarters in order to retrieve the stolen alien blood sample, Amanda Waller awaited for his arrival and set up a trap that placed John in a cage made of fire. Chloe tried to find out the whereabouts of various supervillians such as Cameron Mahkent who were sent to the Belle Reve. However she was kidnapped by Checkmate. Oliver and Clark find out that Tess is an Checkmate Agent. She told him that they were after something called "Watchtower", telling Clark and then Oliver. John used his shape-shifting ability to trick a guard by masquerading as Amanda Waller to release him from the fiery cage. Clark proceed to meet with Amanda Waller who requested him and the JLA to join Checkmate in order to stop an alien threat. She also wanted Clark to give Amanda the location of Watchtower's central database in order to get the names, faces and addresses of Black Canary, Impulse, Aquaman and Cyborg as well as show her his true face so Chloe wouldn't be killed. She criticized Clark for leaving Chloe vulnerable to attack. Oliver then immediately shut down Checkmate's power which allows Clark to save Chloe. John then proceeded to evidence of the blood sample with his Martian vision and before leaving wiped Waller's memory of her knowledge of the secret identities of members of the Justice League. When Zod declares war on Earth, the team assembled to handle the crisis. Watchtower, Green Arrow, Cyborg, and Black Canary team up with JSA members Hawkman and Stargirl with the Blur (Clark) taking the role of leadership. Clark tells the team that he will use the Book of Rao to send the Kandorians away, but that he must go too. Hawkman and Cyborg say that they must bring the fight to the Kandorians, but Martian Manhunter disagrees. He says that they must let Clark do what he must with his people. When they finally let Clark go through with it, Cyborg re-assures him that they will all help protect the world in his (Clark's) absence. When Clark finishes what he has to say, Hawkman, Cyborg, Black Canary, Stargirl, and Martian Manhunter all salute him. Later, when Clark fights Zod, Zod stabs Clark with a Blue Kryptonite dagger.
