who is captain marvel and what are his powers
Captain Marvel (DC Comics) Captain Marvel, also known as Shazam (/ʃəˈzæm/), is a fictional superhero appearing in American comic books published by DC Comics. Artist C. C. Beck and writer Bill Parker created the character in 1939. Captain Marvel first appeared in Whiz Comics #2 (cover-dated Feb. 1940), published by Fawcett Comics. He is the alter ego of Billy Batson, a boy who, by speaking the magic word "SHAZAM" (acronym of six "immortal elders": Solomon, Hercules, Atlas, Zeus, Achilles and Mercury), can transform himself into a costumed adult with the powers of superhuman strength, speed, flight and other abilities.
Luke Cage Created during the height of the Blaxploitation genre, Luke Cage is an ex-convict imprisoned for a crime he did not commit, who gains the powers of superhuman strength and unbreakable skin after being subjected voluntarily to an experimental procedure. Once freed, Cage becomes a "hero for hire" and teams up with fellow superhero Iron Fist as part of the duo, Power Man and Iron Fist. He later marries the super-powered private investigator Jessica Jones, with whom he has a daughter. In 2005, writer Brian Michael Bendis added Luke Cage to the lineup of the New Avengers, and he has since appeared in various Avengers titles, and became the leader of a group of reformed supervillains called the Thunderbolts.
