Created by writer Otto Binder and artist C. C. Beck, Ibac first appeared in Captain Marvel Adventures #8 (March 6, 1942).^[2]

Stanley Printwhistle edit

Fawcett Comics / Earth-S edit

Stanley "Stinky" Printwhistle, a crook who attempts to blow up a bridge, but is caught in the explosion and thrown off due to Captain Marvel. He is saved by Lucifer, who offers Printwhistle the chance to become a champion of evil and defeat Captain Marvel in exchange for his mortal soul.^[3] Printwhistle accepts, Lucifer summons up four historical villains, and Printwhistle is told to speak the magic word "IBAC". By doing so, the frail, grey-haired criminal transforms into Ibac, a brutal muscleman with a buzz cut. Saying "IBAC" again transforms Ibac back into Printwhistle.^[4]

When he first appears he is defeated when Captain Marvel hits him so hard he seems to knock the evil power from him, in the form of leaving Printwhistle and the four other villains in front of him, the four fade away quietly, but Ibac later returns when the evil spirits contact him. Captain Marvel whirls Ibac around so fast that the four evil spirits separate from him. Because he has not been able to defeat Captain Marvel, Printwhistle has not been obliged to give his soul to the devil, and has reformed, but being weak-willed, he has often been forced by other criminals into becoming the evil Ibac again.^[5]

In his first Silver Age appearance, the spirits of the villains who gave him his powers telepathically communicate with him, and force him to become Ibac as he has reformed and been a street sweeper for the last ten years. They order him to capture, then destroy, Billy. He succeeds in surprising, capturing, and leaving a bound and gagged Billy in a building about to be blown up, but Billy is able to use a recording of his voice to summon Captain Marvel and beat up Ibac. After being defeated, his benefactors withdraw their powers from him. Ibac was a member of both the Pre-Crisis Monster Society of Evil during WW II, in which he nearly killed Billy in Africa after giving him bound and gagged to cannibals, and the Society formed years later.^[6]

While Captain Marvel is empowered by six mythological and Biblical figures, Ibac is empowered by four of the most evil and terrifying men to have ever walked the earth: Ivan the Terrible, who supplies Terror, Cesare Borgia, who gives Ibac Cunning, Attila the Hun, who gifts him with Fierceness, and Caligula, the sponsor of Cruelty. While Captain Marvel transforms using magic lightning bolts, Ibac's transformations are accomplished with the power of mystical green fire and brimstone. This also gives him superhuman strength and stamina. In his second appearance in Captain Marvel Adventures #9 Beautia Sivana saying 'Ibac' next to Ibac after his transformation transforms her into a black haired woman wearing a black dress, though she still has her own personality and turns back when saying 'Ibac' again.

At the time when King Kull causes trouble for Earth-One, Earth-Two, and Earth-S, he enlists Ibac, Penguin of Earth-One, Queen Clea of Earth-Two, and Blockbuster of Earth-One for his attack on Earth-Two, where he tries to wreck Atlantis and use a cloud to sink islands. This brings them into conflict with Superman of Earth-One, Wonder Woman of Earth-Two, Green Arrow of Earth-One, and Spy Smasher of Earth-S. Spy Smasher battles Ibac and is on the verge of losing when he remembers what Captain Marvel told him of the villain. Spy Smasher then taunts the dim-witted villain by telling him to "back down". Ibac responds proudly "I back down for nobody!" The phonetic "I back" causes him to revert to Stinky Printwhistle's form.^[7]

Ibac's original benefactor Prince Lucifer gives him greater power briefly, but he turns back on purpose to escape the affections of Aunt Minerva after getting advice from Solomon.^[8]

Post-Crisis edit

In the Post-Crisis, Ibac's origin is similar to as his Earth-S counterpart although his power is implied to originate from Lady Blaze, his employer.^[1] Ibac also appears in Villains United during the Infinite Crisis storyline as a member of the Secret Society of Super Villains.^[9] One Year Later, Ibac appeared in the Secret Six series, still with the Society, battling the second Ragdoll on the orders of the Society. Ragdoll escapes, leaving a wounded Ibac.^[10]

Ibac is seen among the captured villains in Salvation Run. There, he is in Camp Lex and starts an argument with the people that are not working to help build the machine they need to escape back to Earth.^[11] Ibac was also in the DC Holiday Special '09 issue fighting Captain Marvel once again, but in the spirit of the holiday, cease fighting and work together to rebuild what they destroyed during their brawl. Captain Marvel gives him amnesty to walk away free. In the last panel, both are shown at a soup kitchen in their human forms, but neither recognizes the other's alter-ego.^[12]

The New 52 edit

Ibac the First edit

In 2011, The New 52 rebooted the DC universe. During the Forever Evil storyline, "Ibac the First" is depicted as an evil barbaric ruler who enslaved the Kahndaq people before being defeated and turned into stone by Black Adam whose family he murdered. Centuries later, one of his descendants takes the name of Ibac.^[13]

Powers of Ibac edit

All iterations of Ibac possess a range of powers akin to those bestowed by the Powers of Shazam, which is retroactively revealed to be an attempted replication of the powers originating from the Wizard Shazam.^[14] As a result, the character gains abilities such as superhuman strength and durability, enabling them to pose a formidable challenge to the champions of the Wizard, namely Shazam/Captain Marvel and Black Adam. While it is unknown which trait assigns what power, Ibac is attributed from traits of evil historical figures: Terror of Ivan the Terrible, Cunning of Cesare Borgia, Fierceness of Attila the Hun, and Cruelty of Caligula.^[15]

Ibac the First's abilities edit

In addition to the Powers of Ibac granted to him by the Circle of Crows,^[16] the character is noted to be a skilled and ruthless warrior and general.^[17] He also employs the weapon known as the Lash of the Oppresssor, a enhanced whip infamously used by Ibac prior to his death which can collect the Living Lightning, forcing the champions of the Wizard to revert to their mortal forms upon contact.^[16]

• A descendant of the character known as Ibac II emerges as the tyrannical ruler of Kahndaq. Ibac II finds himself engaged in a conflict with the Sons of Adam, a revolutionary group whose prominent members, Amon Tomaz and Adrianna Tomaz, manage to revive the recently deceased Black Adam. Initially skeptical of the legends surrounding Black Adam, Ibac II ultimately meets his demise at the hands of Adam.
• Hamid Stanli appears a minor antagonist role in the Black Adam comic miniseries. Serving as a follower of Oni Grace, a member of the Circle of Crows, he is the current vessel of the spirit of Ibac and reveals this fact to Black Adam. He explains that he is one of the numerous fatherless children who have harbored Ibac's spirit long after his demise, which explains why Adam was unable to locate him in the past. Although referred to as "Stanli," he is also occasionally called "Stanley" and invokes the spirit by saying "Ibac", reminiscent of the Stanley Printwhistle iteration.
