This might be something we do for the Bombay Gunrunners podcast, but it's pretty cool. There are two personality tests each with a series of questions.
The first is a Superhero personality quiz. After you answer the questions about yourself it will tell you how closely your personality is to the personality of a list of super heroes.
The Super Villain personality quiz. Same concept but it tells you how closely you resemble super villains.
