Prince Amentep
Ibis begins his life as Amentep, a prince of ancient Egypt who was in love with the beautiful Princess Taia of Thebes. As a young man, Amentep is given the "Ibistick", a talisman of incredible power, by the Egyptian god Thoth, who empowers the talisman after Ibis was overthrown.[6] Amentep's throne is eventually usurped – with the aid of a demonic army conjured up by the evil god Set – by a cruel magician known as the Black Pharaoh. When Taia, who is under the protection of Osiris, refuses to marry him, the Black Pharaoh shoots her with a poisoned arrow. Using his Ibistick, Amentep places his beloved in suspended animation to allow her to heal. He casts a similar spell upon himself, hoping to be present when Taia revives.[7]
4000 years later, the mummy of Amentep returns to life in an American museum in 1940, which is later revealed to be the work of the wizard Shazam. Now called "Ibis", Amentep sets out in search of his beloved, eventually finding her at another museum.[8] Seeking to adjust to this new world, Ibis uses his vast powers to become a crimefighter.
Ibis can do almost anything with the power of the Ibistick: build force-fields around cities, transport himself and others, heal or destroy people, bring people back to life or summon spirits, give superhuman powers, and even make objects appear out of thin air. Without the wand, he is powerless, which is frequently exploited by his enemies. The Ibistick apparently vibrates in the presence of evil, at one point it even wakes him up. Taia was once shown using the wand to make lightning strike a foe of Ibis, and often uses it at other times. It can be used by anybody, but not to cause harm directly to Ibis, or it will backfire on the user. It cannot be used directly against certain magics.
According to Jess Nevins' Encyclopedia of Golden Age Superheroes, "Ibis fights ordinary criminals, an animated and living Sphinx, the Yellow Peril Trug, a spider made man-sized and man-smart by the Ibistick, the superintelligent maimed madman Half-Man, the Dark Spirit (a forgotten god of wickedness), Ruthven the Warlock, and Lucifer himself".[9]
Ibis and Taia next appear in a Justice League/Justice Society crossovers as members of a team referred to as Shazam's Squadron of Justice. These heroes live in a parallel universe on a world called Earth-S. Along with many other Earth-S characters, they were imprisoned in Doctor Sivana's Suspendium globe, but released twenty years later when it drifted near the Sun. Ibis was a member of the Squadron of Justice, organized to defeat King Kull when he paralyzed the Marvels and tried to destroy all three Earths. Ibis helped stop Mr. Atom from destroying the futuristic City of Tomorrow on Earth-One.
After the Crisis on Infinite Earths, Ibis and Taia were retconned as part of the Golden Age of the DC Universe, in which Ibis served alongside other wartime heroes in the All-Star Squadron. As noted in Starman Vol. 2, #40 (March 1998), Ibis tends to operate out of Fawcett City like other heroes, including Bulletman, Minute-Man, Spy Smasher, and the duo of Mr. Scarlet and Pinky the Whiz Kid.
Ibis was reintroduced in the modern DC Universe in The Power of Shazam! #11, in which he is resurrected by Mary Marvel and Uncle Dudley to rescue the wizard Shazam from Hell, where he had been imprisoned by the demoness Blaze. In Zatanna #1, part of the Seven Soldiers miniseries, Ibis and Taia presumably perish along with Doctor Thirteen and Timothy Ravenwind at the hands of Gwydion during a seance conducted by Zatanna. The sorceress blames her own shortcomings for their deaths.[10]
