On patrol, Artemis followed a path of destruction caused by Amazo and Superboy, eventually leading her to the Gotham Academy. Whilst spying on Superboy, Kid Flash and Robin, she was attacked by MONQIs. She fought them off, and managed to shoot an arrow at Amazo which saved Kid Flash's life, allowing him to break free from a deadly grip.
Artemis continued prowling the streets, and her actions did not go unnoticed. Batman and Green Arrow tracked her down, and offered her a place in the Team she had saved. Artemis agreed, but only if her family history would not be revealed, because she feared that might ruin her chances of being a hero.
Artemis was introduced to the Team, and though most embraced her, her first meeting with Kid Flash was rocky, as he still wanted Speedy as a teammate. Green Arrow's former sidekick promptly arrived, with a new costume and a new name, Red Arrow. He distrusted Artemis immediately, questioned her skill, and berated Green Arrow for replacing him so quickly. Reluctantly, he provided the Team with the assignment he had planned. The recently broken out Serling Roquette was still wanted by her former captors, the League of Shadows.
The Team set out to guard Doctor Roquette at the local High School. After bickering with Kid Flash, Artemis decided to instead watch the perimeter. Despite Miss Martian, Superboy and Artemis's vigilance, Cheshire managed to infiltrate the school, and she nearly killed the doctor. With the assassins beaten back, Aqualad decided to move Roquette to a new location.
But Cheshire found them again, and this time she brought Hook and Black Spider along. Artemis fought Hook, but the trio escaped after Cheshire realized Doctor Roquette was actually Miss Martian in disguise. Artemis followed Cheshire outside, and after a short fight, knocked off her mask. She recognized her sister immediately. Cheshire brokered an escape, threatening to tell everyone about Artemis's real background. She vanished in a puff of smoke.
When Artemis returned to Gotham City later that night via Zeta-Beam, she was confronted by Red Arrow. He knew she wasn't who she claimed, but decided to play along because Batman and Green Arrow would be lying only for a good reason. Her cover would be safe with him, as long as she did not endanger the rest of the Team.
Captain Atom gave the Team a lecture on espionage. The Team was obviously bored by all the information, so he instead gave them a cold case from the Vietnam war: the possible framing of Air Force captain Nathaniel Adams. The Team accepted.
Aqualad and Artemis met with Adams's children, Peggy and Randy, to question them about the case. Peggy believed her father was innocent, while Randy believed he was guilty. After this questioning, Aqualad and Artemis talked about Adams and his two children. Aqualad's mind drifted, though, as he had begun thinking of Atlantis and his own parents. He told Artemis about his father, Calvin Durham, and his mother Sha'lain'a.
Things had gotten worse—two key witnesses, Shirley Mason and Duk Trang, had been murdered by Rako. The Team regrouped in Bibbo's Diner, where they analyzed a photo found on the body of Mason. The only two people who were not yet dead were Enos Polk and Henry Yarrow. Artemis, Miss Martian and Aqualad went to Polk's house in Metropolis, and found it deserted, with all evidence leading towards a hasty departure.
In the remains of Yarrow's exploded house, they found evidence leading them to an abandoned airfield in Utah. There, they found the culprits behind both the framing of Adams and the recent murders: Yarrow, Rako and Alec Rois. Rois had an explosive vest with a dead man's trigger, but he was taken out of the fight by Miss Martian and Artemis. Miss Martian locked his thumb on the button telekinetically, and Artemis shot a foam arrow to cover his entire arm. The rest of the Team took care of Rako and Yarrow; the latter was hit by a ricocheting bullet. Miss Martian extracted the memories from the dying man.
The Team was assigned to search for Kent Nelson, the former host of Doctor Fate. He had gone missing, and someone needed to find and secure the Helmet of Fate. For that purpose, they headed to the Tower of Fate in Salem. Artemis was annoyed by Wally's constant attempts to impress Miss Martian, especially after his insincerity activated the tower's defensive systems and nearly got the Team killed. After Miss Martian told the tower the true purpose of their arrival, the defenses backed down. Once the Team was safe, Artemis called Wally out on his actions.
After traveling through a small pocket dimension, the Team found Kent Nelson's staff. Wally and Artemis both reached for it, and were promptly teleported away. The staff brought them to Nelson, who was imprisoned by Klarion and Abra Kadabra. Nelson used the surprise arrival of the two to escape.
The Team was reunited in one of the tower's dimensional mazes. Artemis joined the rest of the Team in taking on Abra Kadabra whilst Nelson and Wally stopped Klarion. Both were eventually defeated, but Kent Nelson perished, and was sucked into the Helmet of Fate.
Back at Mount Justice, Artemis visited Wally to discuss what happened when he put on the Helmet of Fate. Wally claimed that his brain's beta-waves were rewritten, bio-scripting him into becoming Doctor Fate for a few minutes. This response surprised Artemis, who couldn't believe he still claimed there is no such thing as magic.
Artemis was placed undercover at Star City Police Department, pretending to be under arrest to retrieve information about the Independence Day attacks from another prisoner there, Icicle Jr.. Icicle Jr. recognized her, as their fathers were acquainted. With familiarity set, Artemis managed to coax him to spill his plans.
Star City August 27, 08:33PDT
Artemis reported back to Green Arrow what she extracted from Junior. Green Arrow thanked Artemis, but she made it clear she never wanted to do things like this again.
Unbeknownst to her, Artemis was awarded a full scholarship to the Gotham Academy by the Wayne Foundation. She was reluctant to give up her friends at Gotham North, but her mother insisted, or she would have to give up the Team instead.
