Welp, this is a concept drawing for the original version of my Splatoon Horror AU. This character was know as "The Victim". The original AU story would've been something like this: The story follows an Octoling experiencing strange nightmares, where they would be attacked by monster versions of Agents 3, 4, and 8. We also have The Victim, who we are led to believe was killed by 3, and the our main character was there to witness it, which is the reason for the ptsd nightmares. At the end of the AU's story, it would be revealed that The Victim wasn't killed by 3, and actually survived, however our main character went insane trying to handle the trauma prior to the AU, and ended up being the one to kill The Victim. The main character is now trapped in an insane asylum, forced to live through ptsd and guilt induced nightmares.
Sorry for the wall of text- I made the art, and the AU. Splatoon belongs to Nintendo.
