Wizard Shazam, also known Shazam (/ʃəˈzæm/) or The Wizard, is a fictional character appearing in American comic books published by Fawcett Comics and DC Comics, first appearing in Whiz Comics #2 (February, 1940) created by C.C. Beck and Bill Parker. A major supporting character in Shazam!-related comic book titles, he often serves as a wise old man archetype who empowers champions to fight evil.

The original version of the character was Jebediah, a young boy of Egyptian and Canaanite origin who served as the Champion, gaining his power through Canaanite gods. In his later years, he forgoes their powers and learned magic before seeking a successor to empower. A revised version of the character is introduced after The New 52. At first introduced as a Kahndaq native who ascended to godhood, this origin was retconned and he is revealed to be Mamaragan, a figure based upon the deity in Kunwinjku culture. This version served as a adjudicator on Earth's supernatural matters as leader of a cabal of six other wizards, making up the Council of Eternity until a betrayal forces him to seek a successor to both his power and that of the fallen Council. Although the characters’ motivations and background histories differ, they are intended to be the same character.

The character is an ancient sorcerer who battled the forces of evil for centuries until the betrayal of Black Adam, one of his earliest champions and proposed successors. Shazam was forced to magically imprison Black Adam and seek another champion to take his place. This would eventually come in the form of Billy Batson, who becomes the hero known as Captain Marvel (later also known as Shazam) and subsequently the rest of the Marvel Family (currently known as the Shazam Family). He often serves as a mentor to the group and is a notable member of the Quintessence, a powerful group of beings who watch over events unfolding in the universe.

The Shazam character has been featured in various media. The original Golden Age incarnation appeared in the live action serial, Adventures of Captain Marvel, portrayed by Nigel De Brulier. He also appeared in animated features such as Superman/Shazam!: The Return of Black Adam, voiced by James Garner. Notably, Djimon Hounsou portrayed the character in DC Extended Universe films Shazam! (2019), Black Adam (2022), and Shazam! Fury of the Gods (2023) in which the character’s appearance and portrayal is inspired by The New 52 version of the character.

Created in the 1940s by Bill Parker and C. C. Beck for Fawcett Comics, he is an ancient wizard (Whiz Comics #2 gives his age as 3,000 years) who gives young Billy Batson the power to transform into Captain Marvel. Despite the new comic's popularity and theatrical success, Captain Marvel was similar enough to Superman that a court ruled against Fawcett in 1952. Two decades after gaining the rights to Captain Marvel, DC Comics began publishing new stories under the title Shazam!. This became a problem for DC's lawyers, as the company had abandoned any rights to the Captain Marvel name, and it was now owned by rival Marvel Comics.

While not part of the first wave of DC's The New 52 2011 line wide relaunch, it was announced at New York Comic Con on October 15, 2011, that Billy Batson would be featured in a backup story, "The Curse of Shazam!" beginning in Justice League (vol. 2) #7 in March 2012. It was confirmed by Geoff Johns, DC Comics' chief creative officer and the author of the story, that Billy Batson's alter ego would be called "Shazam" rather than "Captain Marvel" from now on. In DC's, 2012 Free Comic Book Day offering called The New 52 FCBD Special #1, it was revealed that seven wizards representing seven different mythologies occupied the Rock of Eternity at the dawn of time in The New 52. They harnessed the power of magic to cast out a "Trinity of Sin", which acted as a precursor to the 2013 Trinity War crossover event. A younger version of the Wizard is part of this group of wizards.

Both the wizard and his champion shared the name "Shazam" in the comic book stories published from then until June 2013, but the Wizard later revealed that "Shazam" is an adopted name, and that his original name is Mamaragan.

Originally, the wizard's name was Shazamo, the last letter standing for the hero of magic Oggar. However, Oggar became corrupt and tried to take power from Shazamo. The wizard defeated Oggar and cursed him to live in the world of mortals. He was given cloven hooves as a sign of his inner evil, and could cast each magic spell only once. Shazamo then dropped the last letter of his name.
