DC Comics has established several legendary characters over the years, but none as distinctive as John Constantine. John is a paranormal investigator from Liverpool, England. His regular anti-hero antics have made him one of DC Comics' most beloved characters. His working-class upbringing, along with his outspoken personality, make him appealing to readers. He has a solid reputation and will go to any length to complete the work at hand. Alan Moore, Rick Veitch, Steve Bissette, and John Totleben developed Constantine, who originally appeared in The Saga of Swamp Thing issue no. #37 (June 1985). Several other titles of his Comic books are Hellblazer (1988–2013), Constantine (2013–2015), Constantine: The Hellblazer (2015–2016), The Hellblazer (2016–2018), and John Constantine: Hellblazer (2020–2021). He is noted for his unending cynicism, deadpan snarking, ruthless and cunning demeanor, and incessant chain-smoking. Yet, he is also a passionate humanitarian driven by a deep desire to do good in his life.
