Kiani is a supporting character of Fathom, a comic book series created by Michael Turner.

Kiani's childhood was largely defined by her parents' death during the destruction of Marielle, an underwater city of the Blue. At a young age, she was taken as an apprentice by the enigmatic Casque. Casque and Cannon Hawke educated and trained her, and she eventually joined the Security Force of the Blue council. They also tried to show her that her hatred towards Humanity is misplaced, but failed in that regard. This hardened her attitude and causes her to be quite headstrong. However, she continues her work with the Security Force and is a respected warrior.

Kiani is also a name used by the Gakhar clan in the Indian Sub continent.

Kiani's destiny changes as Casque and some trainees are caught and abducted by order of Admiral Maylander, while they were training on Shepherd's Field. As she hears of the abductions, she is devastated and allies herself with Marquesis, a member of the Blue council, and his group of commandos. Together, they storm a secret American Navy base where Casque and the others are being held.

The group finds out that scientists have been conducting several experiments on their Blue captives, trying to analyze their strengths and their weaknesses. They manage to rescue Casque and many other captives. Kiani also discovers that Marquesis has gone rogue and has been cutting deals with Admiral Maylander. He really wanted Casque for his own purposes. She eventually follows him to his base and they fight a deadly duel.

As Kiani is slowly dying, Casque emerges and used his extraordinary powers to save her. He then reveals that he was in fact a Black, an underwater race living at the very bottom of the oceans. He leaves Kiani and rejoins his brethren, leaving her alone, robbed of her parental figure.

Loneliness is a major theme in Kiani's life. She has been clinging onto Casque since her parents' death. Without this figure, she often loses herself in sadness and anger, and has no one left to turn to, save her comrades Brande, Siphon, and Cannon.

Issue 7 of Fathom: volume 2, reveals that Kiani is an Elite Blue. This means that she has not only the ability to live underwater, but the ability to manipulate water at her will. Her powers were most likely triggered by an electric shock given to her by one of the Tigersharks, Admiral Maylander's elite force. It is unknown where Kiani's new abilities will take her.

In the Kiani series, it is revealed that her father is the main villain for Fathom Vol. 1, Killian. And her mother is girlfriend of Killian, Anya.

Kiani's character has been drawn by the different artists of Aspen. Although Michael Turner created Kiani, and her visual character was largely defined by then-Aspen artist Talent Caldwell. His portrayal of Kiani conveyed her rugged, dangerous, and sexy attitude. Many fans believe that Talent has been the best artist to date when it comes to handling Kiani. Another influential artist is Koi Turnbull, artist of Fathom volume 2. His portrayal of Kiani has been more graceful, and he conveys her personality very well.

Kiani has blue eyes and fair-toned skin. Her hair is bright red with platinum blonde highlights. Except when armored for dangerous combat, Kiani traditionally is seen wearing only her bikini with barrier reef adornments.
