Savage Dragon was an idea from Erik Larsen’s youth that grew with him into adulthood.
Larsen’s Dragon cracked apart the general superhero story in two ways. (I’m sure there’s more than 2, but for now…)
Savage Dragon is a police officer. The typical super hero trope is a masked gymnast turned vigilante.
Chicago is Dragon’s home. Chicago isn’t as hipster cool as say, Des Moines, Iowa. But it also isn’t New York City, Metropolis, Gotham, Queens or any other NY alias that every other superhero pays crazy rent to live in.
