Special containment protocols: SCP-XXX-1, -2, and -3 are to be contained separately. Outside of approved research, SCP-XXX-1, -2, and -3 are to be kept no less than 500 m apart. Any research proposals which involve reuniting the three components of SCP-XXX are preemptively denied.
SCP-XXX-1, -2, and -3 are to be examined weekly for signs of tissue growth; any new tissue is to be excised and incinerated, and the excision sites are to be cauterized. Personnel performing this examination must wear level-2 biohazard protection; SCP-XXX-2 and SCP-XXX-3 must be tranquilized and restrained prior to examination. If tissue growth is detected in any of the individual components for more than two consecutive weeks, 10 mg/kg of zinc dithionite is to be added to each component's food as a growth inhibitor.
SCP-XXX-1 is permitted access to literature and recorded entertainment from before its captivity.
Description: SCP-XXX is three organisms of unknown origin which, at the time of their capture by the Foundation, were jointly masquerading as then-President of the United States Warren Gamaliel Harding. SCP-XXX-1 is the head, SCP-XXX-2 is the torso and arms, and SCP-XXX-3 is the pelvis and legs. Biochemical analysis has yielded no conclusive results.
SCP-XXX-1 believes itself to be Harding, and has largely been cooperative with the Foundation; however, despite its acknowledgements that it is evidently not human, it is unable to provide any information about its origins.
SCP-XXX-2, the torso and upper limbs, has declared itself to be the vanguard of a hostile force which it otherwise refuses to identify. Personality assessment indicates that it is considerably more intelligent than SCP-XXX-1, and it has shown itself to be highly skilled at psychological manipulation, having induced three personnel to commit suicide. It has also demonstrated the ability to reshape its flesh: while retaining the overall form of a headless, legless torso, it has grown a facsimile of Harding's face on its chest, with its nipples being converted into eyes and a mouth opening across its stomach.
SCP-XXX-3 is the pelvis and legs. Like SCP-XXX-2, SCP-XXX-3 is able to reshape its flesh to a limited degree, and has produced a crude simulacrum of Harding's face with which to communicate and feed; however, it is of considerably lesser intelligence. Psychological manipulation has induced it to reveal that "all of you" will "get what (we) deserve", that "the others" will "do it", and that "the others" are "not from here"; however, it is unable to provide further details.
Harding's biography and genealogy are known in sufficient detail to conclusively indicate that a genuine human Harding did exist at some point; whether he was replaced by SCP-XXX before or after being elected President is as yet undetermined.
In 1923, peculiarities in Harding's medical records were intercepted by Foundation agents embedded within [REDACTED]; these, combined with several unusual political decisions (including the implementation of [REDACTED] and the cancellation of [REDACTED]), as well as [DATA EXPUNGED], were correctly interpreted as indicators that [DATA EXPUNGED]. Harding's death was arranged as a precautionary measure and his cadaver was taken into custody, with a substitute cadaver buried in his place; a preliminary autopsy revealed both the existence of SCP-XXX-1, -2, and -3, and that they were still alive.
