Leatherface - Strong lad, deadly weapon. Can't beat head on without a gun but it would be possible to outmanuver
Ghostface is usually some normal person with a knife, get that knife away then kick their ass
Freddy Kruger is dangerous but if you have good control of your dreams you'd have a chance
Micheal Myers - similar to Leatherface, too strong physically without a gun but can outmanuver.
Jason Vorhees - Dude got that magic immortal shit on him, don't engage just run.
Predator - Make yourself look weak as possible as they primarily like to hunt for the thrill and sport not just pick off easy kills. Fighting it or running away would be inneffective without prep time.
Xenomorph - kills you on sight lol, maybe if you had firepower prepped but then you gotta watch out for the acidic blood.
Leprechaun - Chill if you don't touch his gold, order a pizza and hang out.
Pinhead - Don't touch any puzzle boxes and you should be ok or have someone ready to take your place.
Chucky - Dude has the strength of a man inside his small frame but that small frame you can take advantage of. Probably one of the easier fights though watch for traps
Pennywise - Got his ass kicked by children lol. Crippling weakness of his strength being tied to how scared you are. Though is dangerous with his one shot Dead Lights skill
The Creeper - Strong monster, running is hard and so is fighting due to it's strength, speed, and durability. If you get the chance to beat the hell out of him don't stop. But more than likely kills you on sight.
