During July 2010, Robin became a founding member of the Justice League's new covert ops team. He and the other members dealt with doubts over the League's intentions for the Team and established the group's leader.
Robin, Aqualad, Speedy and Kid Flash received a tour of the Hall of Justice, the Justice League's faux headquarters. But Speedy soon informed them of the true base: the Watchtower, an orbiting satellite, and voiced his distaste of being treated like a sidekick. Soon after Speedy's departure, the Justice League was called away on a mission, and a secondary emergency, a fire at Cadmus Labs, arose. The young heroes decided to infiltrate Cadmus (based on Batman voicing his long standing suspicions about the lab) where they uncovered a hidden genomorph project. They also discovered Project Kr and the pod containing Superboy. They released him, but were taken down by him.
The three sidekicks were captured and about to be cloned by Dr. Desmond, but Superboy had a change of heart, and broke them out. They made their way to the top floor together. Robin outsmarted Desmond by hacking the Cadmus systems, which gave them a head start. Desmond ingested the Blockbuster to stop them, but Robin outsmarted him again. He asked his teammates to blow up pillars, and blew the roof with explosive batarangs. Their enemy was crushed.

The Justice League had responded to the commotion, and found the Cadmus facility destroyed. Batman was not pleased with their antics, but all protégés confronted their mentors. They complained about the way they had been treated and stated that together they had formed a powerful Team, and that it was time they were treated as partners rather than sidekicks. Batman demanded three days to come up with a plan.
With two and a half of the three days gone, Robin had grown impatient, and asked Alfred about what Batman was doing. The butler did not know, but assured Robin he would come up with a plan, as promised.
Batman and the League eventually acceded to the idea, and opted to turn the group of teen heroes into the Justice League's covert black-ops Team. They then gave the new team their own headquarters in Mount Justice and introduced them to their fifth member: Miss Martian.
While trying to find information about Cadmus on the Batcomputer, Robin found information about the planned assassination of Farano Enterprises CEO Selena Gonzalez. He asked Aqualad and Kid Flash to help him stop them, so they could practice as working as a team.

The three encountered Hook and Black Spider, but were easily taken down, and captured along with Selena Gonzalez.

They escape because Robin's utility belt had not been taken, and eventually succeed in capturing the assassins. Gonzalez was nowhere to be found, however.
Returning to Mount Justice, Red Tornado suggested the kids work on team-building skills. They reveal their real names to each other, Robin being the exception: he was under orders of Batman to keep his identity secret. They took a trip in Miss Martian's Bio-Ship to explore the surroundings, but were alerted to a commotion at Happy Harbor Power Plant. There, they found Mister Twister. They suffered a defeat because Miss Martian thought he was Red Tornado in disguise, trying to test them. The rest asked her to stay behind, but that did not help them either. They eventually managed to defeat Mister Twister by working together.
Kid Flash invited Miss Martian for a night watching the stars at a campfire. It turned into a camping trip for the entire Team, mere yards away from the entrance to the Cave. To pass the time, the young heroes told each other the stories on how they became a superhero.
Batman sent the Team to Santa Prisca to investigate the illegal super steroid Venom. They snuck past the defenses and took out two groups of guards: one from Kobra, and one including Bane himself. Robin and Aqualad discussed their findings, and agreed that Kobra was hoarding Venom. He nominated himself as mission leader, an idea Kid Flash was not happy with, considering him too young. Bane used the disagreement to offer his help—he would get them into his old factory. Aqualad agreed.
In the factory, Robin ran ahead to the computer lab. He hacked the systems, and with Kid Flash's help, found the true reason behind Kobra's presence: they were mixing Venom and Blockbuster formula to create a new, more powerful, Kobra-Venom. Robin and Kid Flash had to abandon the lab because their teammates were found out. He made it to the drop-off area where Sportsmaster's helicopter was waiting and sabotaged it. He found Kobra, who would not fight him, but sent Shimmer instead. During the fight, Robin was forced to retreat as Aqualad called for a retreat.
Back at the mine that lead them into the factory earlier, Aqualad lectured Robin about what he did wrong. Robin conceded, and suggested Aqualad be the leader. He approved, but promised it would only be temporary, as he thought Robin was made for command. With the leader now chosen, Aqualad planned a counterattack.
Robin would head to Kobra. He easily dispatched Shimmer this time, but Kobra was a different league entirely. He is defeated quickly, but Kobra was forced to retreat when his forces were overpowered by the rest of the Team.
Batman and Red Tornado sent the Team to Salt Flats to stop a robbery of plutonium. They were met by Psycho-Pirate, who used his Medusa Mask to induce anxiety into all members of the Team. Robin grew up in a family of fearless people—first the Flying Graysons, then Batman. He was afraid he would not be necessary to anyone—not to Batman because he was afraid, and not to the Team because he was the youngest. He was snapped out of his trance when Kid Flash took away the Psycho-Pirate's mask. It was just in time for them to engage the Psycho-Pirate's newly arrived ally, Atomic Skull. After a short fight, the Team secured the plutonium, but Atomic Skull escaped.
