Shazam has a host of powerful foes, ranging from magical threats to more technological-based villains. Each of them presents their own threats and challenges to the hero, which makes it incredibly difficult when the hero has to deal with both sets of powers at once.

Although that doesn't happen very often, Shazam had to deal with that precise issue in Grant Morrison and Cameron Stewart's The Multiversity: Thunderworld Adventures, where a version of Doctor Sivana was able to claim his own Shazam transformation and gain the powers of Black Adam for himself. Now, we're taking a closer look at how the original Captain Marvel's villains were effectively mashed-up and how close Black Sivana came achieving his ultimate victory over his hated enemy.

HOW DID SIVANA BECOME BLACK SIVANA?

The Multiversity: Thunderworld centered on a large-scale attack against the Rock of Eternity. This garnered the attention of the heroes of Earth-5, a world protected by Shazam -- who in this world still goes by Captain Marvel -- and his allies. This threat is revealed to be a multiversal alliance of Doctor Sivanas that threatens the Rock of Eternity, with all of them working in concert to try and gain the mystical power for themselves before inevitably betraying each other. By constructing their own massive technological version of the Rock of Eternity, the Sivana of Earth-5 was able to isolate the energy signature of Captain Marvel's magic lightning and track it down. Sivana is able to discover a way to replicate the magical transforming thunder, which allowed the Sivana family to gain their own superpowers and serve as his champions, just like the Marvel family.

Sivana is also able to mine the Rock of Eternity's magical energy to create a substance called Suspendium, by using its magical power to create additional time that Sivana could then manipulate in his favor. He begins his work by creating an eighth day of the week to honor himself -- Sivanaday -- where things always work out for him. However, Captain Marvel is able to fight back against the Children of Sivana and makes his way back to the Rock of Eternity, where he finds Sivana, having stolen the Wizard Shazam's staff. Using it, Sivana is able to give himself access to the transformative power of Captain Marvel's lightning. This turns him into Black Sivana, a massive and fanged version of Sivana with powers similar to Shazam's long-time foe, Black Adam.

Instead of being powered by magical concepts (such as the strength of Hercules or the speed of Hermies), Black Sivana is fueled by the fundamental forces of science, which grants him powers like the velocity of a photon. He's quickly able to gain the upper hand, with Captain Marvel merely stalling him more than fighting back. Ultimately, he doesn't really defeat Black Sivana as much as he tricks him.

Captain Marvel realizes that it's through the Suspendium that Black Sivana is empowered, which Captain Marvel realizes is in low supply because the other versions of Sivana stole  Suspendium for themselves. This means Sivanaday doesn't have enough last a full day, and Black Sivana isn't able to maintain his powerful form. He's is transformed back into his tiny natural form in a manner of minutes, which allows Captain Marvel to easily win the day.

It's a good thing too, as Black Sivana was quickly shown to be just as powerful as Captain Marvel. He was quickly overwhelming the hero during the battle and could have won if the other versions of himself hadn't given in to their natural impulses. Black Sivana is the kind of threat that could seriously prove to be a multiversal threat if he were ever unleashed again. Especially if he could still use his family as his foot soldiers, Earth-5 (and many other worlds) would be in extreme danger if Black Sivana could return. It's probably for the best that many of the Sivanas ended up killed by the end of The Multiversity. But there's always a chance at least one of them saved enough of the Suspendium to make their own transformation.
