The Pentaghouldon are the first Soul based creations of Dischord. Dubbed "Hero-Killers" because of their given purpose and their impeccable physical strength. Dischord cheated when he created them, giving them the ability to revive themselves up to 499 times after being killed. Thus giving them plenty of time to learn the moves of the heroes they are fighting, all while the heroes get weaker from exhaustion.
Every Pentaghouldon is decorated with the same head gear, all have some kind of visible rib cage, are all 10+ feet tall, and all feature holes in their limbs. Though, between each other, they vary in structure and ability.
Named "10 16 14" by Dischord, when put through an incomprehensible cipher, translates to "Kingpin Rough Oak." The prosthetic arm is fake and is actually part of the body, it is simply a horror aesthetic. They have no blood or organs and live through the raw power of their souls alone. They are 12.8 feet tall when not slouching.
This guy's specific physical design is kinda maybe inspired by Dark Souls enemies.
