Ibac

Ibac is a supervillain whose name is an acronym drawn from four of history's greatest evil figures — Ivan the Terrible, Cesare Borgia, Attila the Hun, and Caligula — whose combined powers he wields as a recurring foe of Captain Marvel.

Few villains can claim the Golden Age pedigree of Ibac, who first menaced readers in Captain Marvel Adventures #22 in 1943, conjured up by the legendary creative duo of Otto Binder and C. C. Beck. Across nearly eight decades of DC Comics history, this sinister figure has proven a persistent thorn in the side of some remarkable company — sharing pages with Captain Marvel, Billy Batson, Green Lantern, Captain Nazi, and the diabolical Mr. Mind. His most notable modern showcase comes through The Power of SHAZAM!, where a new generation of readers got to appreciate just how dangerous a Golden Age bad guy can be. Eighteen catalog appearances spanning 1943 to 2021 tell the story of a villain who refuses to stay buried — a true relic of comics' earliest era with enough staying power to keep collectors hunting.
