1x1x1x1 was a rumored hacker who appears as a pitch-black character with a see-through chest revealing a black skeleton, a green domino crown, and one glowing red eye.  His torso (not the skeleton part) is a neon green, with his legs being the same as the void-black hear. He has unkempt-yet-smooth straight white hair, a contrast to his pitch-black skin. For short, his name would be '1x' or '1x4', but if you wanted to go "formal," then his name would be the 'Creation of Hatred'. Forsaken Killer!!
