J-17 was made by Dr.Snow on accident. He was made to fight archdemons. As it is Dr. Snow's job to make anti-demon defenses and weaponry. He was originally going to be powered with the holy energy Dr.Snow had managed to harness from holy weapons and artifacts. But instead, they accidentally powered him with EVERY ARTIFACT. Holy, Unholy, Mechanical, Elemental, Raw, Arcane, Void, Shadow. He was given literally all the energy in the entire facility including a ton of energy sucked through the void and hell portals in the facility. He's now a very neutral but powerful "Fake human" that wanders around aimlessly. He escaped the facility easily.
