The PSTL (Potential Superhuman Threats List) is a list of superhumans that have been considered by SCORPIO to be possible threats against the Earth. Although military action can be sought after against these superhumans, SCORPIO prefers to "keep an eye on them" instead of causing havoc trying to simply exterminate and capture the superhumans.
However, if violence persists by the hands of a superhuman on the list, SCORPIO will declare the superhuman expendable.
Originating in 1967, the PSTL has become a valued asset within SCORPIO to keep better track of supers who could be a high-level threat against the Earth.
- Besides all of SCORPIO, only the President of the United States and the United Nations know of this list.
