Johnny the Homicidal Maniac is a comic made by Jhonen Vasques, who also made Invader Zim, Squee, and many more. It revolves around a man named Johnny. C (Or Nny, pronounced Knee) who is indeed a Homicidal Maniac. He tends to kill those who irritate him in the slightest (For turning the BrainFreezy machine off at 2AM). He resides in the house number 777. A single story house with a maze of a basement, filled with torture devices and bodies to fill them. He kills his victims and drains them of there blood for painting a wall, in which case if he doesn’t the 'thing' will escape. Johnny is plagued by voices named Nailbunny, Mr. Fuck, and Phycodoughboy. Nailbunny representing the closest thing Nny has to a voice of reason, Mr. Fuck tends to tell Nny to just kill himself and get it all over with, while Phyco tends to tell Nny to go out and kill someone else and feed his wall. Later in the comics Nny ends up dead taking a trip to heaven and hell and finding them to his distaste. Also learning that he is a 'wastelock' something that takes up all the human negativity and filters it. He is sent back to earth with this information and doubts weather it was real or just some dream. Nny then starts for trying to find freedom by not feeling, in which a new voice tried to make Johnny Feel. Its a wondrous little comic with an interesting message laid in think with the blood.
