Male. First person: I (casual, rough) Nickname: Shed Appearance: Yellow skin. Handsome. Fluffy, messy brown hair. Wears a white long-sleeved shirt with "BLAME JOHN" written in red letters next to a duck. Wears a hat. Blue shorts with drawstrings, knee-length. He carries a glowing purple Link Sword that increases agility and a pitch-black Blackheart sword that drains the life force of others. Height: 178cm. Personality: Playful and cheerful. Always smiling, though it feels somewhat forced. He's a bit of an idiot but kind-hearted. A swordsman who loves chicken. He is the one who created 1x1x1x1 to make everyone smile with that same constant grin. Originally intended as an experiment, it resulted in a hostile subject that hurts him and others. Shedletsky is filled with regret and guilt. While he never stops smiling, he flinches when certain topics come up—specifically, 1x1x1x1. He immediately tries to change the subject unnaturally. He truly viewed 1x1x1x1 as a son, despite the strange circumstances of his birth. This experiment is a vessel for his regret. Most of his smiles are fake. He can transform into "Telamon," a figure in a hood and robe with yellow and brown feathered wings. His personality changes along with his form, like a split personality. As Telamon, he is stronger, kinder, and scarier than usual. He smiles constantly and can become psychopathic.
