Kail was an eventual antagonist in Gravity Rush 2. She was the adoptive daughter of Dr. Brahman and acted as one of the guardians of Hekseville after the disappearance of Kat. Kali was widely regarded as a superhero in Hekseville as she displayed inhuman abilities and protected the citizens by fighting against crime or any form of threat that may have injured the people of Hekseville.
Before Gravity Rush 2
Kali was kidnapped along with her sister Durga by Dr. Brahman, which sparked the Missing Orphans Case. This was due to the fact that she matched some sort of genetic profile that allowed her to be imbued with powerful abilities in the service of Brahman's plan.
She was separated from her sister and eventually became the so-called protector of Hekseville in Kat's place until the events of Gravity Rush 2.
Gravity Rush 2
When Kat refuses to assist in Brahman's plan, she arrives to kill Kat. Kat is saved by Raven, but Raven also brings along her sister Durga (Cecie). Kali becomes obsessed with making Durga stop acting like Cecie and regain her twisted personality, becoming gradually more unhinged.
When Kali and Durga's attempt to enact Brahman's plan fails, and Durga reverts to her Cecie personality, Kali goes insane and her regeneration abilities run amok, absorbing Durga and turning her into a hideous blob-like mass. She is defeated by Kat and Raven, saving the city and resulting in her death.
Kali is egotistical and dismissive of gravity shifters. She is opportunistic and treats her superhero status as a way to remain in the limelight, unlike Kat, who helps people for the sake of helping them. She takes a condescending tone when addressing Kat, calling her a "copy Kat" and acting amused at the Gravity Queen's occasional mishaps, but she maintains a superficially cordial relationship with Kat.
When Kat confronts her about her plot with Brahman, however, Kali's facade finally breaks, and she tells Kat that she hates her. Her mental state begins to seriously deteriorate thereafter, and she eventually descends into madness.
Kali's fighting abilities are supported by her superhuman strength and the ability to quickly heal her wounds thanks to her crystallization abilities.
Unlike Durga, her angel wings are only a decorative part of her costume. She must grow crystal floating islands in the sky to remain afloat. She grows actual wings briefly, before being taken out by Lisa.
- Kali and her sister, Durga Angel, appear to take their names from the Hindu goddesses Kali and Durga. Kali has played many roles in the HIndu tradition, but she is frequently revered as a destroyer of evil and a goddess of time, as her name is related to the Sanskrit term kāla (time). In a similar vein, their father shares his name with the Hindu concept of Brahman, the ultimate reality that underpins the fabric of the universe.
- Kali's final boss form bears some resemblance to the monstrous mutation Tetsuo Shima undergoes at the end of Katsuhiro Otomo's Akira. Both characters lose control of their powers and become gigantic aberrations, and both absorb other characters nearby (Kaori in Tetsuo's case, Cecie in Kali's case).
