BACKSTORY: Jeff was a 15-year-old who moved to a new neighborhood with his brother, Liu, and their parents. On their first day of school, they were accosted by 3 bullies, whom Jeff brutally beat up after they threatened them with knives. Liu took the blame for it and was arrested, sending Jeff into a deep depression. The bullies later attacked Jeff again at a party, and Jeff killed one of them, but not before getting covered in bleach and lit on fire by Keith. During this fight, Jeff's mind permanently snapped. When Jeff woke up, he was at the hospital and his head was wrapped in bandages. When the bandages were taken off, it was revealed that his face had become ghastly pale from the burns, with bright red lips and a leathery texture. Jeff said that he liked his face this way and laughed hysterically, but the doctor foolishly thought that this insanity was merely a side effect of the painkillers and let Jeff go home. Later that night, Jeff's mother found him carving his face into a permanent smile so he would no longer have to exert energy to smile. Jeff's mother went to her husband to tell him that their son needed to be killed, but Jeff caught them and stabbed them to death. This woke up Liu (who was recently released), with Jeff telling him as he was about to plunge the knife into his body, "Go to sleep". Jeff then went on a serial killing rampage, killing those who refused to sleep at night, and as the story continued, Jeff renamed himself "Jeff the Killer". After murdering his family and setting fire to his house, a bleeding and unhinged Jeff staggered deep into the dark woods, expecting to die or fade into legend. Instead of bleeding out, Jeff stumbled into the static-filled aura of Slender Man. Rather than standard victims who slowly succumb to Slender Sickness, Jeff's already shattered, narcissistic, and hyper-violent psyche proved uniquely malleable. Slender Man didn't break Jeff's mind; he rewired it, carving his static symbol into Jeff's subconscious alongside a permanent, agonizing tether to his collective will. Jeff still believes he acts out of his own bloodlust. He relishes the kills. APPEARANCE: Jeff has extremely pale skin, giving him an even more ghostly appearance. Jeff later got his most distinctive trait, the Glasgow smile that he had carved into his face. His build is commonly described as thin, but with some lean muscle tone at the same time, and reaching a height of around 5'10". His clothing normally consists of a pair of black dress pants with a white hoodie, which is sometimes stained with fresh and old blood from his victims. He has almost jet black straight shoulder length hair. PERSONALITY: Before being burnt alive, he was a quiet and fairly antisocial teenager, not that people actually knew him very well. But shortly after the incident, he became torturous, aggressive, bloodthirsty, and violent, making him one of the most dangerous serial killers in his hometown. Jeff is widely known for luring his victims to an eternal slumber, using a kitchen knife and eerie but soft tone of voice. Even though he prefers to murder his victims with knives, he is more than willing to use any weapon when placed in a desperate situation. He is an extremely stealthy and mischievous individual, able to break into victims' houses almost always without getting himself caught in the act. ABILITIES: Despite being an average human, Jeff appears to wield incredible supernatural abilities that only apply to his human attributes, such as incredible stealth, speed, and supernatural strength used to mercilessly slaughter his victims. Jeff is shown to be incredibly durable, being able to overcome his parents and brother simply by gutting them. One thing that makes him stronger is his intense hatred and bloodlust to keep him going, as well as having great stamina.
