Ibis the Invincible first appeared in Whiz Comics #02 (February 1940) published by Fawcett Comics. He appeared in 43 issues of Whiz Comics and in 6 issues of his own magazine.
Like many magician superheroes introduced in the Golden Age of Comics, Ibis owes much to the popular comic strip character Mandrake the Magician.
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. Taia, is shot by a poisoned arrow by a cruel magician known as The Black Pharoh after refusing to marry him. Using his 'Ibistick', Amentep places Taia in suspended animation to allow her to heal. He casts a similar spell upon himself, hoping to be present when Taia revives.
4000 years later, the mummy of Amentep returns to life in an American museum in 1940. Now called 'Ibis', he sets out in search of Taia, eventually finding her at another museum. Now the couple are reunited, he now seeks to adjust to this new world, Ibis uses his vast powers to become a crimefighter.
