Anywaus assuming no more people get added to this we can finally get into discussion:
Now 1 aspect that will be really important is people's
stleath and their counters to it since almost everyone here uses it and everyone is comparable in stats, I'll go one by one based on what I know and their pages
The Demogorgon (Stranger Things) (Counters all organic being's stealth due to its blood sensing but can get jumped on by FNAF crew and
Blair Witch, maybe Slenderman)
Baldi (Due to him his ability to hear people opening across a school and telling who did it he should be able to know where everyone is outside
Blair Witch and those who use teleportation often like Slenderman)
Ao Oni (heat detection will let them detect anyone who's organic and not dead)
Jeffery Keaton (Jeff the Killer Saga) (Once things start to get hurt he'd be able to track hurt people through the scent of blood)
The Creeper (Jeepers Creepers) (Smelling fear is useless but once it finds someone he'll be able to track them down)
Skitzo (Might be able to sniff people out, funnily The Thing is undetactable by animals so he might not be able to smell him)
Siren Head (possibly has echo location)
Pyramid Head,
Giant ants (Them!) both have enhanced senses to unknown degress
Jason Voorhees,
Doomguy,
Insect Worshippers,
Freddy Krueger,
Michael Myers,
Leatherface, FNAF Crew,
Pyramid HeadBlair Witch,
Candyma,
Look-See,
Pennywise (1990 Miniseries),
Ash Williams,
Siren Head,
Bendy,
Sawrunner (Cry Of Fear),
Leon S. Kennedy,
The Thing (John Carpenter) and Slenderman all don't seem to have a counter to stealth
Notes: Siren Head's stealth is useless since it relies on him blending in the background
Likely no one can spot the Blair Witch People with teleportation can easily disange and hide from people again besides against someone like The Creeper
People with regen will likely throw Jeff off unless they stay near where they bled
