Jeff The Killer is a boss in Slender Fortress.

Description[]

Jeff the Killer is a story accompanied by an image of the character. The story says that a teenager named Jeff was severely injured in an incident of bullying that caused his face to become burned. Following the incident, Jeff went insane and cut a smile into his cheeks and burned off his eyelids. He is now a serial killer who sneaks into houses at night and whispers "go to sleep" before murdering his victims.

In Slender Fortress[]

Jeff the killer is a survival boss. he has two types of melee attacks, one is the simple standstill melee attack that will do bleeding damage and the other is a running while melee attacking that will do normal damage. Jeff has a special throwing ability that is a flying guillotine, similarly to grenade throwing bosses he can throw the guillotine at a start of a chase and while chasing (the guillotine will do bleeding damage). Jeff can be stunnable via flashlight but it will make him faster at chasing and wandering (When Jeff despawns and spawns again it will be reverted).

On suicidal Jeff wields two machetes. Everything stays the same but his chase duration increases, he also gets three new attacks, the first one is a standstill melee attack but he swing twice with his machetes causing a double hit (this attack will cause normal damage), the second one is a jumping forward while attacking with his machetes (this attack will cause bleeding damage), and the third one is a running forward and swinging his machetes six times (this attack will cause normal damage for each hit) after the third attack he will do a animation cooldown where he standstill and flicks down his machetes (kinda like a DbD killer)

Jeff the killer has 300 base speed and 70 walk speed, and 20 seconds of chase duration.

Trivia[]

  • His model would be this one
  • In Oblitus Casa Jeff makes different noises when he gets stun by the light in the right and left door, in Slender Fortress Jeff uses the left stun sound for normal and extreme and on suicidal and above he uses the right stun sound.
  • From 2021 to 2022 there was a SF2 server named Oasis that had Jeff the killer as a boss, it was a port of the snpc from Gmod without all the abilities shown in this concept.
