2) John Constantine
You only have to look at his place at the head of the Justice League Dark team to realize that John Constantine is the number one supernatural hero in the DC universe. Unlike the others on this list, however, he isn’t an out-and-out superhero and hasn’t always been part of the mainline continuity.
Created by Alan Moore during his run on Swamp Thing, Constantine is a rogueish, cynical chain smoker from Liverpool who also happens to be the world’s best occult detective. Constantine’s Hellblazer comic series was much darker and more mature than the average DC comic and stands as the longest-running book in DC’s Vertigo imprint for adults.
His popularity led to a movie in 2003 starring Keanu Reeves, which ended up completely mangling the character. Much better was the short-lived Constantine TV series in 2014. Though it was unfairly cancelled pretty early on, star Matt Ryan has since reprised the role in live-action on Arrow and in animated form in both Justice League Dark and an upcoming webseries.
