Special Containment Procedures: SCP-YYYY should be placed in a standard humanoid containment cell. Entry to the containment cell should be restricted to no more than three foundation personnel at a time. SCP-YYYY should only be let out of its containment cell after approval from a member of the O5 command. SCP-YYYY is to be wearing special googles at all times1. Under no circumstances should SCP-YYYY be allowed to take off the goggles. If the goggles are damaged, a new pair must be put on SCP-YYYY after orally sedating SCP-YYYY. If SCP-YYYY tries to damage the goggles in any way, SCP-YYYY should be restrained and the goggles should be checked for damage.
Description: SCP-YYYY is a adult male of unknown origin who possesses abilities that allow him to control any sentient being. This is only possible when the said being, looks at SCP-YYYY's eyes after spending more than 307 seconds in his presence. SCP-YYYY is also seen to be immortal as any damage inflicted on SCP-YYYY has no effect on him.
According to the information provided by SCP-YYYY during an interview conducted by Dr. █████, when SCP-YYYY is in control of ten humans, he actively tries to increase that number until he is in control of one hundred humans. Once SCP-YYYY is in control of one hundred human beings, he starts to murder everyone he is not in control of. The humans who are contolled by SCP-YYYY, termed SCP-YYYY-1, possess abilities similar to SCP-YYYY but are not immortal. It is not possible for SCP-YYYY to stop controlling an individual who has already seen his eyes. The only way for SCP-YYYY to stop controlling an individual is if the individual becomes brain dead. Although tests show that pictues of SCP-YYYY's eyes have no effect on the individual looking at the picture, but watching a video which shows SCP-YYYY's eyes causes SCP-YYYY to start controlling the individual's mind. But in order for this to work, the viewer has to look at SCP-YYYY's eyes for more than 307 seconds depending on the numer of times they blink.
Discovery: SCP-YYYY was discovered when the foundation received reports of mass murder by a crowd of a hundred people in a village in rural India. According to the reports, there was a hundred people with "colourful eyes" killing everyone else around them. The foundation deployed MTF-?? and had orders to eliminate everyone with said colourful eyes. The Task Force successfully eliminated all the assailants but there was one adult male who the task force was not able to deal any damage to. The task force was then instructed to bring the man to Site-██. Reportedly, the SCP was brought to Site-██ without incident but SCP-YYYY had his eyes closed for the whole time. When asked about it by a researcher, he said that when anyone looks at his eyes, he can control their minds.
Addendum:
Addendum YYYY-A-1: The goggles are made of reinforced steel with the lenses being one-way mirrors with the reflective side facing outside. The goggles are attached to SCP-YYYY's head and can only be removed with a passcode that is only known by foundation personnel with Level 4 clearance or above.
