Adrianna Tomaz was a citizen of Kahndaq who was notorious for fighting the corrupt regime of the country. After Black Adam took over control she became at first a friend and later his wife and royal consort. He granted her super-powers so that she could serve alongside him in creating a new world order. The silver age origin of the character is somewhat different, as she was a schoolteacher that found a magical pendant that granted her powers when she said aloud “O Mighty Isis!” This character presumably lived with the remainder of the Fawcett characters on Earth-S.
The character is one of the rare few that appeared first on television and then was adapted for comics. She had appeared in the latter portion of the Shazam/Isis Hour in her own part of the series labeled “The Secrets of Isis.” She was subsequently transferred to comics where she first appeared in Shazam #25 in 1976. Though eventually given her own series she failed to maintain a significant fan following. The character was reimagined some time later for the year long story arc 52, where she would be the consort of Black Adam and rule jointly over Kahndaq. Her first appearance here was in issue #3 as Adrianna and in issue #12 as the superpowered Isis.
For all purposes the silver age version of the character and the modern version have no direct link, though as Crisis on Infinite Earths rebooted most characters in the DC Universe, it could ostensibly be seen to apply to her as well. Thus the character has two distinct periods of her existence. The silver age version was plagued by the same problems as many other silver age characters, that being that character development did not occur very often, and especially not for marginalized characters. The character in 52 also did not progress but for reasons much closer to the needs of the plot of the series. As the person that reformed Black Adam, her behavior needed to be incorruptible and it was as she taught him a great deal of compassion. She died the first time with this same mentality.
Major Story Arcs
As with most characters of the silver age, that version of the character did not have any real story arcs of note, even in her self-titled series (which ran for only nine issues.) The most significant story arc which the character partook in is unquestionably 52. In this she is first a dissenter of the way that her people are treated. This brings her to the attention of the new ruler of Kahndaq, Black Adam. After discussing with her he decides to help her find her missing brother, who had been kidnapped by Intergang. Eventually Isis and Adam decide to marry. During their marriage a suicide bombing is stopped by Vic Sage and Renee Montoya and the two become allies of the royal couple. The task of defending the country along with creating a new world order occupies most of their time until the country is attacked by the Four Horsemen of Apokolips. Isis and her brother are subsequently murdered causing Black Adam to go on a murderous rampage of revenge.
She also later plays a role in the story arc Countdown. Black Adam is still in love with her and seeks repeatedly to get her resurrected, but he eventually becomes so obsessed that he doesn’t realized that Felix Faust is manipulating him into helping to free him from Fate’s Tower. As the two are eventually reunited they travel to the Rock of Eternity where they depose Captain Marvel as the caretaker of the magical power. This brings them into conflict with the Justice Society of America, although Isis is being consumed by her own madness, a result of her death. Shazam returns and turns the two into statues as punishment for their actions.
During Brightest Day, her brother returns the statues to Kahndaq but is unable to change their conditions. Osiris decides that he must kill in order that she can live again, but once she comes back to life she chastises him for doing so.
Powers and Abilities
The silver age version of the character got her powers from the Amulet of Hatsheput. This granted her powers similar to the rest of the Marvel family, though an emphasis on the healing and fertility is present in those powers, as those are the responsibilities of the ancient goddess.
The modern version of the character has a connection with nature and she can influence natural events. This means that she can use air to fly, or to allow things to grow at a great rate. Occasionally this power is beyond her control, as when she cried over the fact that her brother would never walk again, it rained all over Kahndaq. She can also summon natural phenomenon and use them as weapons such as water blasts or walls of lava.
She appeared in Smallville as an entity controlling Lois Lane.
