An unnamed Skakoan functioned as a combat engineer for the Confederacy of Independent Systems throughout the duration of the Clone Wars. As the conflict neared its conclusion, this Skakoan was one of the scientific personnel involved in the experiments conducted upon the Nelvaanians.
As the Clone Wars drew to a close, the Skakoan was among the group of scientists dispatched to the planet Nelvaan. Their mission involved experimenting on the Nelvaanians, with the goal of transforming them into mutant cyborg soldiers. General Grievous gave the order that the newly created army was to be delivered to him promptly after the last specimen had undergone the transformation. The Skakoan combat engineer voiced his concerns to the head scientist, stating that the specimens were not yet prepared, but these concerns were disregarded by the head scientist.
As the engineers prepared to transform the final specimen, named Harvos, Jedi Knight Anakin Skywalker made his appearance and rescued Harvos from the procedure. The head scientist then released the other specimens, instructing them to engage Skywalker in combat, a decision that the combat engineer opposed. Skywalker and Harvos worked together to liberate the mutants by removing their control collars. As the enraged Nelvaanian cyborgs began to attack the security droids, the Skakoan combat engineer, along with the other scientists, fled the facility. However, before the combat engineer and his fellow scientists could reach their transport, Skywalker arrived, having just destroyed the facility's siphon generator, at the cost of his mechanical hand. Consumed by anger, Skywalker employed the Force to eliminate all of the scientists, including the combat engineer.
The voice actor for the Skakoan was James Arnold Taylor.
