Once known as Captain Marvel, DC acquired Shazam in the 1970s and became one of their most powerful heroes. Though initially only licensed by the company, DC Comics took ownership of Shazam in the 1990s, paving the way for an era of brilliant comics starring the hero. Ever since, he has become the magical counterpart to Superman, often teaming up with the Man of Steel - or fighting him.
