We do not accept characters "inspired" by Jeff the Killer. The narratives involving these characters typically follow a certain series of clichés, sometimes called the "Jeff Formula": a person (usually a kid or teenager) is bullied or has something tragic happen to him/her, goes insane, mutilates themselves, may or may not get super powers (super strength, immunity to pain, indestructability, super speed, telekinesis, pyrokinesis, teleportation, invisibility, X-ray vision, ability to bring inanimate objects to life, superhuman jumping and/or acrobatic abilities, flight, ability to control elements, extrasensory perception, shapeshifting, necromancy, Wolverine-like regeneration, etc.) and goes on an unstoppable killing spree. This plot outline has been done to death, and is commonly perceived as unscary, lazy, and a springboard for Mary Sues. Such characters count as Jeff spinoffs and will be removed once identified.
If you really want to write and share such a story, consider posting it offsite on places like DeviantArt or the Spinpasta Wiki. You can always link to it on your userpage. If you think your story is good enough to be on the wiki regardless, try using Spinoff Appeal.
