Percy Beta-266 (Percy-266) comes from the second batch of clones, before the genetic processing problems started. After proving himself to be an effective solider, Percy was promoted Clone Commander and brought up to the esteemed position of Republic Science Officer. Towards the end of the Clone Wars, as the Kaminoans became increasingly displeased with the Republic, he was placed in charge of creating the final batches of Clones. His latest batch..., which bore Delta-40, didn't turn out too well... Percy remained on Kamino until he was drafted into the formalized Imperial Army.
