The Official Up-To-Date DFS Slender Fortress Boss List

The boss types will be seperated like so :

• Chaser : These bosses will run after you, and attack you.


• Stalker : These bosses will stand still and looking at them/being in their field of view will give you "static", after enough "static", you will die. (Static affects how much your screen is shaking.)


• Paranoia : These bosses will stand still, letting them see you for too long will cause them to run towards you and kill you.


• Proxy : These bosses summon minions controlled by other players which can hurt you.


• Statue : These bosses will not move until you blink, or look away from them.

Sounds from Xavier: Renegade Angel.
Boss config made by ThatAverageJoe.
Boss Type : Paranoia
Timer : 3 seconds.

Idle quotes : "Where can you get your hands on some fabric? Quick!" "If you wanna dress up like a ghost, you need to put a piece of fabric over your head." "If this is your idea of a joke, i'd like to be subjected to a tragedy." "I have pre-foresworn to bounce these ghosts."
Kill quotes : "So, it was me all along, now i understand. I just need to go through the black door."
Countered by : Spy.
Tips : If you see him, back up immediately and don't let him see you. As long as he doesn't see you he will not move in to attack you. He will disappear eventually. If you don't hear him anymore, chances are he teleported away. Spy is the ultimate counter to Paranoia bosses as you can cloak and move out of the way if you are spotted, keep in mind you have this get out of jail free card only twice, so use it wisely.

Obunga
Original model by Pablo
Model edits, boss config and animations by ThatAverageJoe.
Origin: The "Obunga" meme, a spoof of Barack Obama.
Sounds from SCP: Containment Breach.
Boss config made by ThatAverageJoe.
Boss Type : Stalker
Static rate : Medium (0.3 static/s)
Special note : Will jumpscare you when he is near you which will add 0.4 static, and builds 1 static/s when looking at him or when near him.
Intro sound : Minecraft cave sounds (Cave1 & Cave3).
Idle sound : None.
Kill sound : Femur Breaker Scream.
Static theme : Kevin MacLeod - The Dread
Countered by : Heavy.
Tips : Obunga is a much harder version of the original Slenderman boss, he makes no sounds and it can be very hard to survive him to the point where Heavy is almost a necessity if you don't want your static to reach 100 instantly. Make sure to play carefully and not accidentally rush straight into him. His jumpscares will indicate the fact he's very close to you.

Rat King
Model and animations ported by ThatAverageJoe.
Origin : Call of Duty : Infinite Warfare.
Sounds from Call of Duty : Infinite Warfare.
Boss config made by ThatAverageJoe.
Boss Type : Proxy/Chaser

Theme : Shaolin Shuffle Trailer Music from Call of Duty : Infinite Warfare ripped by Mr Tom Waffles
Countered by : Scout, Demoman, Medic, Heavy, Soldier.
Tips : Having at least 1 other player with you is a good idea in case you get swarmed by the proxies. If you really need to, you can juke the boss by tricking him into starting an attack, then immediately running away from that attack, since his attack isn't instant, and he has the attack delay afterwards.

Boss Type : Paranoia

Countered by : Spy.
Tips : If you see him, back up immediately and don't let him see you. As long as he doesn't see you he will not move in to attack you. He will disappear eventually. If you don't hear him anymore, chances are he teleported away. Spy is the ultimate counter to Paranoia bosses as you can cloak and move out of the way if you are spotted, keep in mind you have this get out of jail free card only twice, so use it wisely.

Snatcher

Origin : A Hat In Time.
Sounds from A Hat In Time.
Boss config made by ThatAverageJoe.
Boss Type : Chaser/Stalker Hybrid
Companion: Hat Ghost

Idle & Alert sounds : "Time you saw what I'm really capable of, kid.. Say goodbye to that little head of yours!" "Ooh, you've stepped into my forest, and now you must pay the price!" "WHYYYYYYYY HELLO THERE! You didn't forget about me did ya? Don't tell me you forgot about me!" "Please... Have a seat!" "Hey kiddo! Let's make another contract!" "You blew it! You totally screwed yourself! Nobody enters my home and leaves in one piece!" "Guess who else just became obsolete?... That's right, you."
Chasing sounds : "That does it.. TIME TO DIE!" "[Evil Laughing]" "[Evil Laugh], FOO- Oh wait, it's you." "FOOOOL!"
Kill sound : "[Evil Laugh]" "FOOOOL!"
Searching Theme : The intro from "Toilet of Doom" looped from A Hat In Time
Chase Theme : "Your Contract Has Expired" from A Hat In Time
Countered by : Scout, Demoman, Heavy.
Tips : Snatcher can be a tricky boss to survive considering he has the Hat Ghost with him. Snatcher has a pretty big model as well as idle sounds which you can use to your advantage to avoid him. However if he sees you, run away and try to break line of sight as soon as you can, since he builds up static as long as you're in his view. Make sure Hat Ghost doesn't sneak up on you either (Refer to Hat Ghost's Tips)

Hat Ghost
Model and animations ported from A Hat In Time.
Origin : A Hat In Time.
Sounds from A Hat In Time.
Boss config made by ThatAverageJoe.
Boss Type : Statue
Spawns with: Snatcher
Attack rate : No delay (0 seconds)
Attack damage : Instant Kill in a radius
Static rate: 0.95 static/s
Boss Speed : 42 Hu/s
Sounds : "[Short High Pitched Laugh]"
Countered by : Sniper.
Tips : Hat Ghost by herself isn't a big threat, however she's very dangerous when paired with Snatcher due to how she works. If you hear a giggle, turn around immediately, because there is a very high chance she is right behind you. If you keep her in your view, she will not move, however the moment you look away from her, she will move towards you and potentially kill you if she's too close, she will also move if you blink. If she spawns alone, Sniper can be very helpful by keeping her distracted since he has a longer blink rate, or simply give you a better chance of survival in any situation against her.

Origin : Resident Evil 7.
Sounds from Resident Evil 7.

Tips : Same as Shia, Alex & Jack, make sure to use corners as much as you can when running away from him. Mr. X is a hard boss compared to the other chaser bosses. However you can use his 6 seconds long animation after killing someone as an advantage to either run away from him or run past him safely.

Queen Vanessa
Model and animations ported from A Hat In Time.
Origin : A Hat In Time.
Sounds from A Hat In Time.
Boss config made by ThatAverageJoe.
Boss Type : Chaser/Stalker Hybrid

Idle & Alert sounds : "Come on out little one, don't be shy." "I can hear your footsteps!" "I can hear you! This is fun!" "I know you're in there!" "I know where you are now!" "[Evil Laughing]" "Are we playing a game? You hide, and I'll seek." "Ready or not... here I come!"
Chasing sounds : "[Evil Laughing]"
Searching Theme : "Queen Vanessa Found You" from A Hat In Time
Chase Theme : "She's Here" from A Hat In Time
Countered by : Heavy, Demoman.
Tips : Vanessa works like Snatcher, except she doesn't have Hat Ghost, her model isn't huge, she blends in with the darkness (except for her two red glowing eyes) and her idle sounds play rarely. The moment you see her/she sees you, run away and don't let the static kill you. She is very slow so you don't have to worry about her chasing you, just make sure there is no line of sight between you and her. Heavy can be helpful for the static, Demoman can be helpful to run away from her.

If you don't hear him anymore, chances are he teleported away. Spy is the ultimate counter to Paranoia bosses as you can cloak and move out of the way if you are spotted, keep in mind you have this get out of jail free card only twice, so use it wisely.

Deathslinger
Model and animations from Dead by Daylight.
Origin : Dead by Daylight.
Sounds and Music from Dead by Daylight.
Boss config made by ThatAverageJoe.
Boss Type : Chaser
Attack rate : Medium (1.5 seconds)
Attack damage : 300
Boss Speed : 300 Hu/s
Special note : Can take aim and shoot a harpoon at you, pulling you towards him. You will be stunned during that time and the only way to be saved is by a teammate hitting you.
Intro Sound : Dead By Daylight - Deathslinger Chase Theme (16 meters)
Idle, Alert & Chase sounds : Deathslinger Laughing
Theme : Dead By Daylight - Deathslinger Chase Theme (Close & Chase)
Countered by : Demoman, Spy, Teamwork.
Tips : Deathslinger is not a hard boss to fight against especially with lots of obstacles between you and him. Being hit with his harpoon is the only thing you have to fear and you'll need someone near you to help you with it in case you can't break line of sight, which is where Demo or Spy could be useful, you can try to go as far away from him as possible or you can cloak if you're in an open area and you know he's going to take aim.

Jeff
Model and animations from Half Life: Alyx.
Origin : Half Life: Alyx.
Sounds and Music from Half Life: Alyx.
Boss config made by ThatAverageJoe.
Boss Type : Chaser
Attack rate : No delay (0 seconds)
Attack damage : Instant Kill
Special note : Has a 2.5 seconds long Deathcam animation that will play when he catches a player, the animation will play in first person and third person, which means he has a 2.5 seconds delay before moving on to another target. Can also spill oil to slow you down. This boss is very sensistive to sounds.
Boss Speed : 330 Hu/s
Intro Sound : Gate opening sound + Jeff screaming in the distance
Idle, Chasing & Alert sounds : Jeff's sounds from Half Life: Alyx
Countered by : Demoman, Spy, Not spamming voice commands.
Tips : Jeff works exactly like you think he would: He will notice if you make any sort of noise (including your flashlight) and if he catches you it's game over for you. This boss is a good reminder that noise attracts bosses and you shouldn't run around spamming voice commands for no reason. Spy can be a good choice for Jeff considering the Spy makes less noise than any other class. If you do get chased by Jeff, Demoman can help you make distance, and if you're playing Spy, you can try to cloak away from danger, you could even use the cloak for sneaking past Jeff if you feel like taking that risk.
