Titans (Titans Unlimited)

The Titans is a team of young superheroes that originally consisted of the "sidekicks" of members of the Justice League. It has gone through several changes in members and locations.

History
The original team consisted of Robin, Speedy, Kid Flash, Wonder Girl, and Aqualad. They were considered a "joke" superhero team due to how young the heroes were. The team did not last long because Speedy had a falling out with Green Arrow due to his relationship with Jade Nguyen, and Speedy went solo. After Roy left, the Titans slowly stopped what they were doing.

Three years later the Titans came back together when Robin found Koriand'r in Jump City. The Tamaranean princess had managed to crash the ship that she was being held prisoner on. Robin and Koriand'r teamed up with Cyborg, Beast Boy, and Raven to defeat the alien soldiers who threatened to destroy Jump City. After that, the Titans were formed again.

Over the years the Titans recruited more people, such as Kyle Rayner/Green Lantern, Tara Markov/Terra, and Kara Zor-El/Supergirl. However it was eventually discovered that Terra was being used by Slade Wilson to infiltrate the Titans and destroy them. Eventually Cyborg was able to track Terra's location. Robin and Kyle traveled to Slade's lair, where they found that Slade had tortured and raped Terra as a way of forcing her to do what he wants. Kyle, who had feelings for Terra, was infuriated. When Slade appeared, Kyle formed a blade out of his ring and impaled him. However, it was really Slade's servant, William Wintergreen, who was under the mask. They freed Terra, and Slade swore vengeance on the Titans for killing Wintergreen. After killing Wintergreen, Kyle quit being a hero. Terra went to therapy sessions with Black Canary. The rest of the Titans slowly left, and the team was disbanded.

Four years later, Roy, now known as "Red Arrow" discovers a weapons cache ordered by Sebastian Blood in Midway City. He contacts Dick, now known as "Nightwing", and they investigate it. However, they soon find out that the weapons are Apokoliptian, therefore making them extremely deadly. They realize that the only way to stop Blood is to find the Titans and reassemble them. After stopping Blood, Nightwing decides to lead the Titans once again, and they formed their own organization on Mount Justice, an old base of the Justice League.
