Teen Titans is based primarily on stories by Marv Wolfman and George Pérez from the 1980s. The five main members of the eponymous team are Robin (Scott Menville), Starfire (Hynden Walch), a quirky, curious alien princess from the planet Tamaran; Cyborg (Khary Payton), a half-human/half-robot who is known for his strength and technological prowess; Raven (Tara Strong), a stoic girl from the parallel world Azarath who draws upon dark energy and psionic abilities. They are situated in Titans Tower, a large T-shaped building featuring living quarters, a command center, and a variety of training facilities.
