So,I had this random thought and I have to ramble about it.

You can't tell me that SCP 106 wasn't based off Pinhead from the Hell Raiser Series.

They have a lot of similar traits:
Both severed in World War 1
Both got traumatized by World War 1
Both are nigh unstoppable
Both have a dimension they can summon at will
Both enjoy killing and inflicting pain on others
Their Dimensions are hell like in nature

And so many more I've probably not thought about. You can't convince me otherwise,unless you give me word from the Person who wrote 106 telling me otherwise.
