DemonKing was a member of the D-Bug Organization, mostly dealing with recon-based missions. He was sent to find Alpha and was in the middle of roughly interrogating a user about his whereabouts, until Nailock appeared and defeated him, which sparked a change in him, especially witnessing Alpha's power first hand with his battle between him and his partner, Ravenfreak. DemonKing soon enters the Z-Tournament and faces Nailock once again, showing great improvement but still comes up short in the end. Afterwords he quits with D-Bug Org. along with Neomutant.
