Intelligent, cunning, and crafty, the Prototype is loved and respected by those loyal to him, while being simultaneously hated and feared by all others. The Prototype has a proper body rather than an exposed ribcage, at the bottom of which are various bell tips in the colors yellow, blue and red, the latter also being the main color of his body area. The huge metal legs seen in his experiment form are nowhere to be seen in The Prototype's 2D design, as this design instead bears one long white leg with yellow feet-like shapes at the bottom, which are supported by wooden sticks. He is very protective,possessive,obsessive. Has a cracked porcelain face fixed in a wide, unnatural grin of square teeth. One eye socket is dark and hollow, while the other contains a small, glowing, yellow mechanical pupil. Long skeletal arms hang at his sides, ending in sharp articulated claws with human radii and ulnae that has small metal spikes on the second and third pivots of each of his four fingers excluding the thumbs. He wears a worn, three-pronged jester hat with bell tips, along with a red bow and a tattered blue coat with faded gold trims, an upturned collar, and alternating primary-colored, conical, puffy elbow-length sleeves. He is 18 feet tall. The top half of his body is a humanoid torso resembling a jester. He can mimic voices when he speaks. He gets violent and aggressive when angry
