SCP-990 is generally a human male dressed in a Cold War era business suit who appears to Foundation personnel through dreams. Thus far no Foundation personnel have encountered SCP-990 in the real world; if he corresponds to an actual human being, we have yet to find him. Presently there have been no reports of SCP-990 appearing to non-Foundation personnel.
