- "I have the exact locations of both the clone DNA room and the clone trooper barracks."
- ―Asajj Ventress to General Grievous prior to their assault on Tipoca City
Around 22 BBY, General Grievous launched an assault on Tipoca City with the aide of Asajj Ventress. After both Ventress and Grievous had successfully landed on Kamino and infiltrated the city, they parted ways - Grievous to kills as many clone troopers as possible in the barracks, and Ventress to steal a sample of Jango Fett's DNA for the Separatists' own purposes.
Ventress made her way to the DNA room unhindered and succeeded in retrieving a sample of Fett's DNA. As she prepared to leave, she was confronted by Jedi Knight Anakin Skywalker. The pair dueled briefly in the chamber before moving into the corridor outside. Ventress nearly escaped with the genetic material, but was ultimately thwarted in her mission by Skywalker with the assistance of the clone troopers defending their home.
