History
The Titans were all once misfits on their own;

The alien Princess of Tamaran, Starfire was the daughter of the King and Queen of Tamaran, Myand'r and Luand'r with the addition of her brother Wildfire, and sister Blackfire. Starfire, was sold into slavery by her older sister, Blackfire to the Gordanians so they would leave Tamaran alone.

Desperate to save their son, Silas and Elinore used STAR Labs technology to turn him into the superhero Cyborg. However, Vic hated what had happened to him, and resentful of his parents, causing him to leave for Jump City.

Raven was the daughter of Arella and the inter-dimensional demon Trigon. She was born in the mystical realm of Azarath, a parallel world from Earth and raised by her mother and the Monks of Azarath. Despite knowing her destiny to one day act as a portal for her father's conquest, Raven was still loved by the  people of Azarath, who she considered part of her true family. Eventually, she left her Homeworld and returned to Earth. Knowing she was destined to one day destroy the world, Raven sought to use her powers for good and started out in Jump City, California.

Garfield Logan  became a metahuman upon his parents injecting him with a serum to counteract with the rare disease he came into contact with after being bitten by a rare green monkey. After his parents died in a boating accident, Gar became a member of the Doom Patrol. However, he left because of his adoptive father, Mento's harsh treatment of him.

Robin was a teenager known as Dick Grayson and the son of acrobats known as Mary and John Grayson. Together, the team was known as the Flying Graysons. He was mostly raised by Bruce Wayne and eventually traineed to become his sidekick. However, he eventually left Batman to become his own hero in Jump City.

Upon their arrival to the cities, there was trouble happening downtown,. Robin noticed it while he was chasing down a criminal in the city, he noticed a spike of trouble going on downtown. He was not the only one attracted to the attention, as Beast Boy, Cyborg and Raven turned to the scene to find Starfire setting off firebolts and scaring the civilians. During the small battle with Starfire, Robin freed the girl of her manacles but the alien princess preceded to kiss him to acquire knowledge of the English language. She flew off and warned them to stay away from her before running away to another part of town. However, the group decided to team up becaues they realized that the alien girl was confused and afraid of a new planet.

During the mission, the team learned that the Gordanians were the true threat. Raven and the rest of the superheroes grouped to protect Starfire and Jump City from the villains. In the aftermath of the battle, the future team went on an island, where they learned the girl's name was Starfire. She, Raven, Cyborg and Beast Boy were given a communicator by Robin in case they needed each other again. This eventually led to the team forming the Teen Titans, a group of young superheroes to protect Jump City from other threats, with the likes of Slade Wilson, Dr. Light, HIVE, and Trigon. Cyborg built Titans Tower on the island where they stood, and the team went to live there, and set it up as their headquarters.
