Well slenderman has proxies that he controls like : masky, tikki toby, and eyeless jack.

I never thought eyeless jack could be a proxy, however masky is from marble hornets, although yes a suspected proxy but marble hornets is confirmed fake.

Hmmm. i dont know much else but im pretty sure anyone who sees the slender man gets a diesese that allows him to track you.

Idk if i was correct about any of the proxies

Not sure if you are serious, but slender man is fictional, the creepypasta community has made that clear ever since the slender man stabbings in 2014. Ever since that incident, the slender man popularity died down. There is a YouTube video called "The Rise and Fall of Slender" that goes into the history of the monster and its downfall. As for diving into the lore of slender man himself there are plenty of mrcreepyapsta story readings on YouTube you can listen to about slender man.

OK! i did some research, and eyeless jack is confirmed a proxy... ill continue looking and see if i can help you more.

Alrighty. slenders targets are usually children. he has also been the cause of two childhood friends killing someone to try to become his proxies. ill look into slenders backstory\history.

Proximity to the Slender Man is often said to trigger a "Slender sickness"; a rapid onset of paranoia, nightmares and delusions accompanied by nosebleeds. i couldnt find anything about his backstory.

The "slender sickness" does not allow him to track you.

Originally, Slender Man killed its victims by impaling them on the branches of very tall trees and allowing them to bleed to death. The victim's organs would be individually removed and placed in plastic bags, which were then returned to their original positions in the body. i hope i could help with your research!
