An unidentified genetic terrorist attempted to devastate the planet Skye during the Clone Wars. However, the individual was stopped by the Jedi Obi-Wan Kenobi, Anakin Skywalker, and Halagad Ventor during the Battle of Skye. It can be assumed that the terrorist was allied with the Confederacy of Independent Systems.

Behind the scenes
Author Abel G. Peña had stated that he intended the genetic terrorist to be Atha Prime, but the mention was cut before final release.
