The Team is a teenage superhero team assigned to undertake covert operations on behalf of the Justice League in Young Justice. The Team is based in Mount Justice, the original headquarters of the Justice League.
The Team was formed after the escapade in which Aqualad , Robin and Kid Flash infiltrated Cadmus lab in Washington DC and discovered Project Kr , a project to clone of Superman (the clone was dubbed Superboy ). The grouped escaped after fighting off the genomorphs and Mark Desmond (Blockbuster). As the building laid in ruins the Justice League arrived upset at what the three sidekicks had done. The sidekicks rebelled against the League and asked for more respect and trust. Batman and the league decided that the three sidekick and Superboy would become a team, on Justice League's terms, handling covert operations missions. During their time together, they acquired new members, and loose some too.

In season 2, he has joined Black Manta, his birth father, as lieutenant within his ranks working under deep cover for Nightwing, to learn more about the Light and their new Partner.
