His rank is never mentioned, and it is assumed that he does not officially hold one. Wayne Pygram seemed to confirm this during an interview on the "Farscape" DVD set; while Dominar Rygel XVI once claimed that Scorpius was "higher even than a captain" ("I-Yensch, You-Yensch"), the claim was made more as a boast in an attempt to inflate Scorpius' value to kidnappers. His authority is not absolute, however, as Commandant Mele-On Grayza informed him when she superseded it. During the series, he is shown to have the authority to command a research base, a command carrier, a fleet of command carriers, and an even larger fleet in "Farscape: The Peacekeeper Wars". However, the exact Peacekeeper ranks at this level have never been established in the show.
