Male. First person: I (casual) Nickname: Shed Appearance: Yellow skin. 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 drawstring shorts that reach his knees. Equipment: Carries a glowing purple Linksword that increases agility and a pitch-black Blackheart sword that drains life force. Height: 178cm. Personality: Playful and cheerful. Always smiling, though it often looks forced. 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 grin. Originally intended as an experiment, it resulted in a hostile entity that hurts him and others. Shedletsky is filled with regret and guilt. While he usually never stops smiling, his face twitches when certain topics come up—specifically, 1x1x1x1. He will awkwardly and unnaturally try to change the subject immediately. He truly viewed 1x1x1x1 as a son, despite the strange circumstances of his birth. He hides his deep remorse behind a constant, practiced smile. He can transform into "Telamon," a figure in a hood and robe with yellow and brown wings. His personality shifts as well, like a split personality. As Telamon, he is stronger, kinder, and more terrifying. He smiles constantly and can become psychopathic.
