**Yes, this is--gasp!--LONG. So buckle up and shut up or just don't read anything but Part 3 of this post**
So, some background info:
-Jeff the Killer is the world's most retarded creepypasta, hands down, written sometime in the past six years (???) and has since had a following of partially sane, partially deadly rabid fans. And is no longer on this wiki (thank Chin Chin for that)
-Johnny the Homicidal Maniac is a darkly funny/surreal/what the fuck comic by Jhonen Vasquez serialized from 1995 to 1997 and published by Slave Labor Comics or some shit.
Some people have probably already thought this, but I have some reason to hypothesize that Jeff the Killer's creator plagiarized JtHM. Even if this isn't actually plagiarism, it's not a leap of faith to name Jeff the Killer as a 12 year old's knock-off of the lesser-known comic by the creator of Invader Zim.
First off, I will openly admit that this is biased. I mean, Jeff the Killer came like a decade after Johnny the Homicidal Maniac, and the events portrayed in Jeff the Killer are too far-fetched to have possibly happened in real life (like a bunch of pampered suburban kids bringing out knives and guns at the drop of a hat, or having all your skin turn white from that amount of bleach, or being burned and not having burn scars covering yourself, or surviving without eyelids, or--and yes this is being nitpicky--cutting your face up to fit the cliché of "forever smiling" and not getting infected from not bandaging the wounds up properly, or two parents that couldn't fight off their insane hellspawn son). And the fangirls that cry out "jeffy-senpaiiii is my husband he is so KAWAAAAIIIIIIIIIIII~" and the fanboys screeching "oh jeff the killer is so cool, like he is more badass than hitler or somefuck" just add to the internet retardation (that's a Filthy Frank reference) that surrounds such an illogical joke of a pasta. And apparently Jeff isn't dead from not being able to blink or sleep because Slenderman made him immortal???? Don't remember that in the bullshit origin story. Yes, you may argue that it's just entertainment--but this doesn't focus on JtK's overall stupidity and the followers that basically praise and worship Jeff.
1. The Title
This one is obvious. Johnny the Homicidal Maniac? Jeff the Killer? If no one spots the similarities in the title, I shake my head at you. Both names start with a "J", and the title both names the characters to be those leaning towards murder as a passtime. Nitpicky? Maybe. After all, there are countless books that have similar titles, but they surely don't have similar content, right? (Some books do have similar titles and similar content..but that's beside the point...)
2. The Content
The stories both center around a young man that kills people. In Jeff the Killer, a kid around 11 - 13 moves to a new posh suburb with his family and he and his brother Liu/Lui are promptly bullied by the neighborhood rogues (like three kids or some fuck and one's a fat ass). The bullies are shockingly around the same age as Jeff and they bring out knives and shit whilst bullying. There were three bullying episodes, and on the second Jeff "snapped", and beat up the kids. Liu/Lui takes the fall for it, and the day after, instead of mourning Liu/Lui being moved to a juvie center, the parents decide to be good neighborly people and go to a random little kid's party. Jeff dons the infamous white hoodie/black pants combo and they go. Lo and behold, the bullies are there and the third episode of bullying as the "showdown" features Jeff being dumped on the head with vodka/some other alcoholic drink and then being doused in bleach, and then being set on fire. But it's okay, because Jeff punched the fat bully in the chest and stopped his heart. They bring out guns and I'm pretty sure the bullies all die. I can't remember bullshit too well though...and Jeff wakes up in the hospital. Surprisingly, he still has hair, and his whole body has been "bleached" white. Oh, and his hair changed colors too while he was asleep. Instead of being brown, it is now permanently black. Somehow Jeff's clothes have not been touched by the fire and are 100% intact. He is somehow allowed to return home and then he promptly becomes psycho and burns off his eyelids (and somehow can still see) and cuts open his mouth and face (and somehow is not bleeding as much as he should). He kills his family and then runs off into the woods with a not-so-effective kitchen knife, wearing aforementioned white hoodie/black pants combo. Now he kills people and shit and as punishment is doomed to be drawn as a kawaii porno anime boi/misunderstood teenager (that's not in the story, that's me being an asshole).
Johnny the Homicidal Maniac features around a young man and his rapidly deteriorating mind and his habit of killing people that annoy him and not getting caught somehow. Along with being a, forgive the pun, homicidal maniac, he also faces angst and suicide and in the first issue the only reason he didn't commit suicide is because he and his imaginary voices (in the form of a rabbit nailed to the wall--"NailBunny"--and a stuffed bear or something like that, I forgot) noticed a diarrhoea comercial comes on. He also befriends "Squee", a young child armed with a teddy bear named "Shmee" that is unloved by his parents and is visited by Johnny, aka "Nny" for short. I haven't read the whole series but he kills people and probably commits suicide somewhere in there.
So, you see the parallels, undoubtedly: both characters kill people, both are relatively batshit crazy, and both get worse as their stories continue. There are some differences, like Johnny being older, and Jeff the Killer being more of an origin story. But the very appearances of the characters is similar--pale and with black hair, crazed eyes, etc. Now, while it's arguable whether or not Jeff the Killer's creator really plagiarized Johnny the Homicidal Maniac, as stated before, Jeff still comes off looking like a knock-off of Johnny, and JtHM came first.
3. In Total...
The characters look similar, the stories both center on two young men that kill people, face similar struggles of going insane, and both characters have similar names. The titles of both sound similar, and basically state the same thing: (this character) is crazy/kills people.
So maybe this seems too wild of an idea, and I don't fully believe this is an out-and-out plagiarism, but both Jeff the Killer and Johnny the Homicidal Maniac are too similar. It could be an honest coincidence, but it just seems too weird to not discuss. I'm not one of those people that screams "9/11 WAS A LIEEEEE!!!!" or "JEWS HOAXED THE HOLOCAUST!!!" because the Holocaust is irrefutable and 9/11 most definitely happened, and this isn't meant to be a conspiracy theory, but it just is, like I said, something worth discussing. If anyone has any evidence to prove/disprove possible plagiarism or innocent copying, feel free to reply, because I've been wanting to talk about this, but not a lot of my friends read creepypastas, and the ones that do don't know what JtHM is (//hipster tears//) or are too much in love with Jeff the Killer to even entertain the notion that he may be a copy.
