History of character has not yet been written.
- This version of Magnificus Sivana, including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
- World's Finest #258 was Magnificus Sivana's first appearance in a comic published by DC Comics that was not reprinted from a Golden Age Fawcett Publications comic.
