He was classified as an SCP but after that happened Trevor henderson said that he wanted his creations to be his own and not an SCP. Trevor henderson gets to make the call because siren head is his creation, so in this case google is incorrect.
I looked it up and yes he is Henderson's creation, but if I can get enough upvotes I will show him and try to persuade him to change his mind. Thanks for mentioning that though it makes it more clear to the people.
