Albedo Piazzolla (アルベド・ピアソラ Arubedo Piasora?) is U.R.T.V. Unit 667, and one of the few surviving U.R.T.V.s from the Miltian Conflict. He is highly educated in a number of subjects, including but not limited to philosophy, science, language and religion, particularly ancient (in the Xenosaga universe) Christianity. He is also adept at complex strategic planning and anticipating his enemies' moves well in advance. Albedo also has the power to regenerate his own limbs, and thus he has the power to never die. This is also the reason for his mental unstableness as the thoughts of seeing friends and family get old and die over time crushed him as a child, and thus contributed to his current mental state. He was the main antagonist of Xenosaga I, and Xenosaga II. After that, Albedo was the new White Testament in Xenosaga III.
