O5-5 "Blackbird"

Male. ███████/████████ ancestry. Age uncertain. Generally regarded as the most jovial members of the Council, is not afraid to be seen joking in public. Has often commented that he believes the "dark curtain" between Overwatch Command and the rest of the Foundation, as well as the "unnecessary seriousness" of the Council itself, are a preposterous and often detrimental joke.

Despite this, there are several incongruities surrounding O5-5. Some sources have indicated that they believe they have heard O5-5 talking to himself as if he were having a conversation, while others have described conversing with O5-5, and then speaking to him again shortly afterwards and feeling as if they were not talking to the same person. In the debriefing of the neutralization of SCP-████, one source described how a rescued member of the Site-██ staff was able to identify a picture of O5-5 as a member of the ██████ ██████ █████████ in their world.

Aside from forming the Department of ██████████ ████████████ Review, O5-5 has apparently led considerable research into the existence of alternate realities, and is known to personally review anomalies that interact with other dimensions as they arise.
