In the original Teen Titans anime, all five of the young, crime-fighting superheroes in Titans Tower have their dark and brooding moments. Robin grows obsessed with defeating the ominous and elusive Slade; Starfire faces betrayal from her sister and culture shock on Earth; Cyborg reckons with the question of whether he is more machine or man. Even the playful Beast Boy is firm in his veganism and defense of animals. The show is visually and thematically dark, challenging its characters, and through them, its audience.
