A swan. Too dangerous to be given a SCP number. Generally nice but when they hear the voices in their head tell them to do something they goes crazy and comply. They will start killing everyone, even their own team mates. When killed, they have a chance to come back to life with powers. A man named Joker has been seen acting crazy with Swan. A man named Unbolted (also known as SCP 5,000) has also been observed to have powers and act a little crazy, though not as much as Swan. Further investigation is on going.
