Young Justice Cartoon Series

Inside the Santa Prisca Venom facility, the Cult of the Kobra has taken over, but say that if one of the prisoners defeats their master's champion in single combat, they will leave. Bane steps forward and is given back his Venom which he uses to enhance his strength. At the other end of the arena, a scrawny Mammoth enters, and is infused with a dose of Kobra-Venom, transforming him into a hulking monster. Bane and Mammoth begin their brawl, with Bane taking a considerable beating. As Mammoth defeats Bane and throws him to the ground, the Kobra Cultists begin to chant, "hail Kobra. The Bio-Ship is on approach to Santa Prisca, as Robin reminisces the mission details assigned to them by Batman. They are told that Santa Prisca, the worldwide producer of the illegal super steroid Venom, has ceased all shipping of the drug, despite the fact that the facility seems to be producing the steroid at full capacity. The Team's assignment; infiltrate the prison, figure out what is going on, and report back to the League. If the League feels they need to intervene they will. When asked about the lack of a clear leader for the Team, Batman states that is their responsibility to decide amongst themselves. Nearing the first drop-zone, Aqualad activates his Stealth-tech and the Bio-Ship enters camouflage mode. Aqualad dives into the water, and lands on the beach, where he patches heat and motion sensors and gives the Team the order to move in. Robin, Kid Flash, Miss Martian, and Superboy get ready to descend to Santa Prisca, where Kid Flash comments on the new stealth-tech, pointing out that it isn't to late for Superboy to put on his, to which he refuses. Miss Martian comments that it "totally works for [him]. The four descend to the ground, where they contact Aqualad, who, scaling a cliff, tells them to head for the factory, and that he will meet them there. On their way, Superboy hears a twig snap. Kid Flash switches his goggles to thermal mode, and sees two squads of "armed bozos" heading for one another. They meet, and a firefight breaks out. Aqualad orders them to steer clear, only Kid Flash runs off to find Robin and ends up tripping and falling into the middle of the skirmish. The rest of the Team arrive, and fight off the two squads, Superboy tackling Bane to the ground. During a conversation after the fight, the Team discuss the current situation, deciding that Batman did not know that Kobra was in charge of Santa Prisca, and that it was likely Kobra came in and tossed the "goons" out. Kobra is hording the Venom, and Robin claims they don't leave until he knows why. He then breaks out into an argument with Kid Flash about who the leader of the Team should be, both attempting to assert themselves to the position, until Bane interrupts. He offers his "assistance", and a way in via his secret entrance. Miss Martian reads his mind, and confirms that there is a secret entrance, but that Bane's also hiding something. Bane offers his assistance once more, as "the enemy of my enemy is my friend". Meanwhile, Kobra and a cultist stand on a balcony at the Venom factory, when the cultist claims that "he approaches". Kobra orders him to activate the radio-jamming net, as nothing must interfere. Bane and the Team overlook the factory, Robin noting the amount of Venom boxed and ready to ship. They come to the conclusion that a "buy is going down", and need to determine the buyer. Kid Flash and Robin again have a dispute about the leader issue, as Bane reveals the opening to his secret entrance and leads them in to the factory. As they enter, Robin disappears, followed by a competitive Kid Flash. Robin knocks out a cultist with a specialized baterang and accesses a computer, as Miss Martian notices that Kobra is only shipping the newest Venom and Superboy hears an incoming helicopter. Robin and Kid Flash identify a chemical formula as a mix between the Project Blockbuster formula, and Venom. The helicopter lands, revealing Sportsmaster to be the mystery buyer. Floating above Sportsmaster and Kobra in camouflage, Miss Martian sends Aqualad a telepathic image of Sportsmaster. Aqualad attempts to contact Red Tornado and the League, without success. Bane then suggests he has a plan, and dives off of a balcony into the middle of the factory, attacking two cultists. Aqualad and Superboy are then attacked by Mammoth, who crashes through the factory window. Superboy and Mammoth engage one another in combat, as Aqualad fights off cultists, and Bane escapes. The rest of the Team arrive and help fight the cultists, while Robin goes after Kobra. Aqualad orders Miss Martian to link them up telepathically, and then gives Robin the command to return to the fight, as they need to retreat. Kid Flash clears a path, and they escape, but the cultists and Mammoth chase them through Bane's secret passage. Aqualad orders Superboy to destroy the support beams, and the tunnel collapses. Robin questions his failure on his first mission as leader, as Aqualad hypothesizes that he may be too experienced for such a new team. Robin then suggests Aqualad be leader. The rest of the Team agrees, and Aqualad accepts, but makes it clear that it is only until Robin lifts the burden from his shoulders. Aqualad then announced their first priority is to prevent the shipment from leaving the island. Sportsmaster attempts to start the helicopter, but Robin had previously sabotaged it. A cultists asks whether they should send out a search party for the Team, but Kobra says that they will come to them. As the Team near the end of the passage, they come across Bane, who has planted explosives around the entrance. Bane reveals that he intends to kill the Team in order to get the League to come in, avenge their sidekick's deaths, and kick out Kobra. As Bane attempts to blow the explosives, Kid Flash steals the trigger from him, and Superboy knocks him out. Just as the helicopter is operational again, the Team attack, this time better coordinated. Sportsmaster attacks Superboy and Miss Martian, as Kid Flash knocks out and steals the mask of a cultist, his "souvenir", leaving Kobra. Robin engages him, but is no match. Kobra effortlessly throws him back. Aqualad takes out Mammoth by electrocuting him, and Sportsmaster makes his escape in the helicopter. Little to his knowledge, Miss Martian has planted an explosive in it, and detonates it. Sportsmaster is unable to control the helicopter, and parachutes to safety. The helicopter crashes into the factory destroying it, with Bane, tied to a tree, onlooking. Kobra escapes into the bushes, as Robin claims they chose the right leader. At Mount Justice, Batman berates the Team for their many failures on the mission, but congratulates them for their ability to adapt to a new plan, and choose a leader. Sportsmaster and the Light discuss the events on Santa Prisca, and Sportsmaster reveals he was only able to save a single vial of the Kobra-Venom, but L-6 states the formula can be reverse engineered. The Light states that three times now the Team has stopped their plans, they are now a nuisance and a threat that will have to be dealt with.

Black Spider swings through Star City, landing outside Bernell Jones's apartment window, as Bernell puts his daughter to bed. Bernell is pulled out of his daughter's arms by the assassin, who tells him he's been warned and then drops him to the ground. As Bernell plummets to the pavement below, a foam arrow hits the ground beneath him, dampening Bernell's fall. Above, Black Spider is attacked by Green Arrow and Artemis, whose arrows are evaded by the assassin. Cissie looks on the ensuing fight, and is overjoyed at the heroes' presence. Sportsmaster runs across the roof of the Belle Reve Penitentiary, and removes a grate from an air vent. He waits for Hugo Strange to deactivate the security sensors, and proceeds into the facility. In the rooftop fight with Black Spider, Green Arrow is knocked to the ground, forcing Artemis to take the lead. Black Spider easily evades her explosive arrows. Meanwhile, Sportsmaster makes his way to the cell blocks and uses a key card to override the lock. He takes a prisoner with him. Artemis continues her fight against Black Spider, and ultimately wins when she freezes his web and traps him in a net. Green Arrow congratulates her, and gives her "bonus points" for poetic justice—catching the spider with a web arrow. Sportsmaster leads the prisoner through the hospital ward, where Professor Ivo is sadistically boasting to the comatose T.O. Morrow, with prison warden Hugo Strange looking on. Green Arrow and Artemis make their way to a Zeta-Tube. Artemis is ecstatic about the victory over Black Spider; Green Arrow happily agrees, but calms her down. As soon as she's gone, Green Arrow calls his former protégé Red Arrow, who had been watching them for some time. Their conversation is cut short by the police scanner, which reports an armed robbery. A truck is leaving Belle Reve, but is stopped by security for a routine check. Two guards open the back of the vehicle to see only boxes of medical waste. They give the van the go-ahead. Sportsmaster, and the prisoner, Professor Ivo, had hidden in a compartment. Back at the prison, Strange turns off the fake Professor Ivo, an android. Outside a Save-Big store in Star City, Green Arrow congratulates Red Arrow on his acceptance into the Justice League, but requests that he "set a good example" and join the Team first. Artemis tells her mother about her night with Green Arrow, and expresses her satisfaction with the outcome. Paula comments that this life suits Artemis, as she is relieved that her daughter is not taking the same criminal path that put her in jail. Paula then reveals that Green Arrow and Batman initially visited Paula before they asked Artemis to join the Team, and that she begged them to help Artemis. Artemis is furious that her mother begged them, and storms out. Sportsmaster and Professor Ivo arrive at a warehouse where Klarion, Brain, Teekl and Monsieur Mallah await them. Klarion is upset that Ivo isn't T.O. Morrow, but Ivo stays to help anyway. Artemis, full costume, decides she's got nothing to prove to the League and the Team, and Zeta-Beams to the Cave. Artemis arrives to the news that Red Arrow has agreed to join the Team. As Green Arrow begins to assign a mission, Artemis sarcastically comments the Team has needed a "real" archer. Green Arrow tells the Team that Sportsmaster was spotted at Louis Armstrong New Orleans International Airport, and assigns Aqualad, Kid Flash, and Red Arrow to the mission. Artemis volunteers herself for the mission. Green Arrow, knowing Sportsmaster's identity, asks her if she's sure. She is adamant, and with Artemis piloting the Bio-Ship, they leave the Cave. Alone in the cockpit, Wally turns to Artemis, and tells her she is a "real" archer, and that she has nothing to prove, at least to him. She is flattered by the compliment. In the back of the ship, Red Arrow tells Aqualad his suspicion of Artemis being the mole. Back at the Cave, Zatanna, M'gann, and Conner are bored, and ask Red Tornado if he has any missions for them. He turns them down, tells them to amuse themselves, and flies into his apartment. Zatanna questions what Red Tornado actually does in his apartment since he does not require it for basic human needs. Red Arrow watches Sportsmaster heading north by boat, and gives the order for Aqualad, Kid Flash, and Artemis to follow, but maintain a discreet distance. Sportsmaster docks, and stands by a railroad. Artemis's suspicion is raised and she exits the Bio-Ship to take a closer look. However, Cheshire stands behind her, and teases Artemis for not revealing her identity to her friends. Cheshire attacks, as does Artemis, but before their fight continues, Red Arrow shoots a trick arrow at Cheshire, tying her up. Cheshire flirts with her captor, leading Artemis to believe they are dating. Shocked, Red Arrow dismisses the idea, as Cheshire discreetly gives Sportsmaster word that they're being followed. The train arrives, and a case is thrown into Sportsmaster's hands. Cheshire breaks free and takes down Artemis. Sportsmaster makes his own escape, as Red Arrow is pinned to the ground by Cheshire, and she kisses him. Kid Flash arrives, and hits Cheshire to the ground, claiming her Sai as his souvenir. Red Arrow orders Artemis to place a tracer on Sportsmaster, but she is unable to, claiming he's out of range. Red Arrow shoves her aside and manages to plant the tracer with a shot Artemis would never have attempted. Red Arrow begins his pursuit of Sportsmaster, but his jet ski is blown up by the assassin. Sportsmaster removes the tracer from his boat, and throws bombs into the water, stopping Aqualad from following him. Aqualad contacts Kid Flash, who along with Artemis is fighting Cheshire. Cheshire disappears, but not before Artemis can place a tracer on her sword. Without any onlookers, Artemis also places a tracer on a passing train, giving Aqualad and Kid Flash the location of the tracer on the train, leading them in the opposite direction. She then follows the tracer on Cheshire, deceiving the Team. At Mount Justice, Red Tornado leaves the Cave, and Zatanna, M'gann, and Superboy decide to see what is in his apartment. They find a Christmas tree complete with decorations, as well as a human shaped object beneath a sheet. Sportsmaster arrives at a warehouse and delivers the case to Ivo, who uses the device inside to perform experiments on the echinoderm. The Brain and Klarion also performs experiments on it. The echinoderm begins to glow in an oddly shaped pattern. Artemis has tracked Cheshire to the same warehouse, and in another room, is confronted by her. Cheshire tells her she had found her sister's tracker, and also points out a tracker Red Arrow placed on Artemis. Mocking Artemis because a member of the Team doesn't trust her, Cheshire shows her live security camera footage of Sportsmaster preparing to kill Red Arrow, who's outside. Artemis shoots an explosive arrow at the factory door, alerting Red Arrow to Sportsmaster's presence. A fight ensues between the four of them, and Red Arrow radios his location to Aqualad. In Red Tornado's apartment, Zatanna, M'gann, and Conner are shocked to find an android. Red Tornado arrives, surprising them, and explains that it will serve as his alter-ego, "John Smith". He hopes to learn more about humanity that way. Zatanna comments on the android's attractive appearance, and uses the sheet that was covering to make it a pair of pants. The fight between Red Arrow and Sportsmaster, and Artemis and Cheshire, continues, as Kid Flash arrives, telling Artemis he and Aqualad found her tracer on a train, but is then confused as to how Artemis found Cheshire. As Klarion finishes his experiment on the echinoderm, Artemis bursts into the room and orders them to freeze, and they do. Klarion freezes himself, Ivo, Klarion, Mallah, the Brain, Cheshire and Sportsmaster. The newly formed ice statues shatter, and the villains disappear. Aqualad announces that they failed their mission, and that they know nothing of the supervillain team's plans. Red Arrow blames Artemis, who defends herself with the information that Sportsmaster was working for Brain, Klarion and Ivo. Red Arrow then continues that Ivo has been in Belle Reve the whole time. Kid Flash is annoyed at Red Arrow's continual accusations aimed at Artemis, but Red Arrow reveals that Artemis intentionally sent Red Arrow, Aqualad and Kid Flash on a wild goose chase by planting a tracer on the train. Kid Flash assumes it was because Artemis was insecure about Red Arrow joining the Team, and is shocked at her acceptance of the accusation. Kid Flash throws the sai, his previous souvenir, at her feet, and instead takes the tracker for his collection. As the rest of the Team are ordered to sleep by Aqualad, Red Arrow tells Artemis that he knows she isn't who she says she is, and that he is not done with her. Artemis returns home and goes straight to her room, where Sportsmaster awaits her. He knows that the Team has blamed her for the failure of the mission, and questions her continued membership. He doubts that the Team would ever trust her again if they found out about her family ties. Artemis tries to ignore her father, but he tells her that she can fight him, and her sister, but not who she really is. He tells her it's time to switch sides, and that she'll never be one of them.

Sidekicks Robin, Aqualad, Kid Flash, and Speedy are finally ready to join the Justice League as full-fledged members. However, they soon discover they are to be treated as "junior members." An enraged Speedy leaves, while the other three strike out on their own to investigate a mysterious fire at Project Cadmus. The trio soon discovers that Cadmus conceals a major conspiracy, and one of its goals is to create a clone of Superman for their own ends. Kid Flash, Robin, and Aqualad are captured by the Cadmus genomorph forces, which prepare to clone them and dispose of the originals. Their only hope is the Superman clone, "Superboy", who must choose between freedom and subservience to those who created him.
