Santiago is a demonic entity who enjoys killing his victims with guns and explosives. He also likes mind-controlling cartoon characters and forcing them to kill each other against their will, he was also featured on pamtri's videos as of now.
Santiago is bald, wears gray clothes, and has a beard.
Killing him does not defeat him, because he has the ability to create a new body after death.
It may be possible to defeat him with a blessed object, like a bottle of holy water or holy oil.
However, a cross will not defeat him, because he wears one on a necklace.
If you see Santiago, RUN AND DON'T STOP RUNNING UNTIL YOU CAN NO LONGER SEE AND HEAR HIM.
On April 23, 2017, Santiago was interviewed on TLC's show; My Strange Addiction.
The episode was never aired on television because Santiago murdered the reporter who interviewed him for asking "too many questions."
However, an anonymous individual somehow acquired a copy of the footage and released it on YouTube.
Not much is known about Santiago, but the interview does reveal how evil and demonic he is.
The YouTube video is below.
