The original Teen Titans series doesn't offer much in the way of villain backstories. Foes appear in single or sporadic episodes to fight the Titans, and are typically not heard from again after being defeated. Cinderblock, Killer Moth, Doctor Light, Mad Mod, The Brain, and many more enemies are battled with little insight into their motive or where their abilities came from. Even the mastermind, Slade, is portrayed as simply evil as he recruits many of these villains into his army.
