Teen Titans is an American TV show based on the DC Comics characters of the same name, that premiered on Cartoon Network and The WB Television Network in 2003. Teen Titans centers around the five main members of the superhero team: Cyborg, Beast Boy, Starfire, Raven and their leader Robin. They are situated in Titans Tower, a large T-shaped structure featuring living quarters as well as a command centre and variety of training facilities, on an island just offshore from a fictional West Coast city (identified as "Jump City" in the Teen Titans Go! comic series). The team deals with all manner of criminal activity and threats to the city, while dealing with their own struggles with adolescence, their mutual friendships, and their limitations. Slade, their main enemy, is a newly designed version of the DC villain Deathstroke. The team encounters several allies throughout the series; including Aqualad in the first season, Terra in the second season (who is integral to that season's story arc), as well as Speedy, Hotspot and Wildebeest, Bumblebee and Más y Menos in the third season (who join Aqualad and Speedy to form 'Titans East') and numerous other heroes in the fifth season in to aid in the battle against the Brotherhood of Evil.
