Ko Sai/Legends

Ko Sai, a female Kaminoan, was Chief Scientist of the creation of the Grand Army of the Republic. It was her responsibility to ensure that the clones were of the highest quality, overseeing all the biological aspects of the project. And 'Processing' the clones that failed to meet her expectations

Following the First Battle of Kamino, she told Yoda more about the source of funding for the army&mdash; a man called Tyranus.

A year and a half into the war, she defected to the Separatists and soon later, Clone commandos and ARC Troopers were deployed to find the scientist before she could reveal any cloning information to the Confederacy.

Kal Skirata and his Null-ARCs, Ordo and Mereel, also took up the search for the scientist in the hopes that Ko Sai would be able to engineer a full life span for the clone army.

In 40 ABY, Taun We told Boba Fett that Skirata and his ARCs killed Sai, though she only returned to Kamino in pieces, which lead Boba to believe her death an act of revenge.
