DC basically created the modern superhero genre as fans know it, creating some of the most respected heroes ever and the most dangerous and intimidating villains of all time. These heroes and villains are often iconic paragons, the Platonic ideals of heroism and villainy. This extends beyond the heroes and villains born on Earth, as well.
