The Team

The Team is a teenage superhero team assigned to undertake covert operations on behalf of the Justice League. The Team was based in Mount Justice, the original headquarters of the Justice League.

Aqualad, who had taken charge during the Cadmus incident, acted as the leader of the Team, though other members of the Team have acted as leader in situations where not all members are available for a mission. As time passed, the ranks grew as more members of the Justice League introduced their young protégés or other young heroes to the Team. Four years later, Nightwing became the new leader of the Team.

Early history
Prior to the formation of the Team, Robin was the first junior protégé to begin his crime fighting career, starting in 2006, at the age of nine.

Inspired by his Justice League colleagues, Aquaman offered both Garth and Kaldur'ahm a position to become his protégé after they saved him from Ocean-Master. Kaldur became Aqualad. Flash was not fond of the idea of the responsibility of a sidekick, but his nephew Wally differed. He recreated the accident that gave his uncle his super speed power. Partly out of guilt, Flash let him become his protégé, naming him Kid Flash.

Before the Cadmus incident, the four sidekicks knew each other; and Robin entrusted Kid Flash with his secret identity. However, the four of them had never been together all at the same time.

Last to take a protégé was Martian Manhunter. Miss Martian claimed she had won the right to become her uncle's sidekick after winning a competition on Mars, though this may not entirely be accurate, as Martain Manhunter has claimed he found M'gann stowed aboard his ship, and claimed to be his niece.

2010
The four sidekicks were brought to the Hall of Justice as a graduation. However, it was nothing but a "glorified backstage pass", as Speedy called it. Fed up with being lied to, Speedy left. As the League members moved to the Watchtower, the others investigated a minor case: a fire at Project Cadmus. This led to the discovery of Project Kr and Superboy. Cadmus's chief scientist, Mark Desmond, became Blockbuster in the hopes of destroying the intruders, but was defeated.

The Justice League arrived at the scene of the destroyed Cadmus facility, and Batman was not happy. He did not, however, expect the young heroes to rebel against the League. They insisted they did good work, and wanted to work together more. Batman asked for three days to plan things.

Batman gathered the four in the old Justice League hideout inside Mount Justice. They would become a team, on Justice League's terms, handling covert ops missions. They were introduced to the fifth member of the Team, Miss Martian.

Kid Flash was eager to let Speedy join, but he declined, claiming their "junior Justice League" was a joke. He was not interested in fighting on the Justice League's terms, and claimed he was tired of them telling him what to do.

After several missions, Batman and Green Arrow noticed Artemis had been following the Team in the fight against Amazo, and offered her membership.

Artemis was introduced to the Team the next day, and got off to a rocky start with Kid Flash, who still wanted Speedy on the Team.

During a solo mission, Red Arrow and Aqualad learned from Sportsmaster that there was a mole on the Team feeding information to their enemies. Both would investigate. Aqualad offered his friend membership, but he declined; he did change his opinion about the Team.

Red Arrow, Aqualad and Robin discussed the mole issue with Batman. Aqualad was by now convinced Sportsmaster had only tried to sow dissent, and there was no mole.

Zatanna moved into the Cave with the Team, after her father was taken as a permanent host by Nabu.

Red Arrow had been elected into the Justice League, and to set the right example, Green Arrow told him to join the Team before being inducted. This did not sit well with Artemis; Red Arrow, in the meantime, considered it a good opportunity to investigate who was the mole. He eventually concluded there was none, and Sportsmaster deceived them.

Icon's induction in the Justice League meant Rocket was added to the Team. Initially, she required a lot of information, though she quickly found her place.

The Light tried to coerce three members—Superboy, Miss Martian and Artemis—into joining them. They had already shared their secrets with the rest of the Team, and successfully ambushed their opponents.

After they discovered the Justice League was mind-controlled by Vandal Savage, and learned Red Arrow was the mole all these months, the Team managed to neutralize the League and drive out Savage and Klarion.

2011-2015
The Team underwent drastic change. Some left; some joined. Zatanna and Rocket graduated into the Justice League. Nightwing assumed the role of leader, and declined membership of the League. Superboy and Miss Martian also decided to stay with the Team. Kid Flash left the Team to attend college with Artemis.

They started training a number of young heroes; at least thirteen members joined in four years time. This new format required organization, and the Team would be split up into smaller groups—Alpha Squad, Beta Squad, Gamma Squad, Delta Squad, and occasionally others—like Zeta—which would be supervised from the Cave by Mal Duncan.

2016
Nightwing unsuccessfully attempted to allay Mal Duncan's suspicions that the Team would have to take care of Impulse and the original Roy Harper. Artemis temporarily rejoined the Team.

A failed mission to defend a satellite launch ended with Lagoon Boy captured and Artemis apparently killed by Aqualad.

Members of the Team, past and present, gathered to mourn Artemis's apparent death.

Members
At its foundation, the Team had five members. Over the course of their first half year, Artemis, Zatanna, Rocket and Red Arrow joined.

As of January 2016, there have been at least twenty-two members, past and present. Some of them have died or left the Team, either to join the Justice League or for other reasons.

Mal Duncan, who was not active as a superhero, acted primarily as an ops manager and com coordinator during field missions but later became Guardian.
