Sora Kai also known as the Separatist-aligned Kaminoan, was one of the Kaminoan lab assistants to Ko Sai, and later became secretly involved as a member of the Confederacy of Independent Systems. She was fiercely and extremely loyal, to Ko Sai only, and Ko Sai admired Sora for that.
When Ko Sai fled from Kamino, Sora assisted in her master's escape, and agreed to go with her once she carried out a special task that the CIS had entrusted her to do. She began engineering the Kaminoan Nano-Virus in secret, and planned to spread it to all clone troopers. Her plan failed when Jedi Kit Fisto and Aayla Secura, who were staying on Kamino, investigated the sickness infecting a few clones whom they came across dead. She later killed the Clone Master Kaminoan: Saya Ta, and injected a massive dosage of the virus into her, after Ta had successfully created a vaccine to counter Kai's virus.
As the Kaminoan tried to escape, she became involved in a struggle with Secura. During the melee, she was infected with the nano-virus she created, as she attempted to poison the Jedi and was killed instantly.
