The Prototype (Poppy playtime)

The Prototype's physical appearance is yet to be fully revealed, although CatNap's shrine seems to give an idea to his overall appearance. His only known body parts are his arms and lower-body. His fingers resemble slender silver pins that appear adept at a large array of movements. Although his fingers appear fragile, they can effortlessly puncture through flesh with unnerving smoothness. His upper arm is adorned with red wires and metallic components, while the forearm contains a human radius and ulna. Moreover, his lower-body has the characteristics of an arachnid, featuring six very large, heavy-duty plated metal legs using what appears to be the chelae of a scorpion as inspiration for its feet - bonded together with cables at each ligament.

It was previously thought that, prior to the Hour of Joy, the Prototype was roughly the same shape and morphology as the person used to make him, as it was not until Experiment 1160 that experiments were no longer bound to those rules regarding their shapes and sizes.[1][2] By the time the Player returns to the factory, 1006 had grown in size, presumably through constructing a new body from the spare parts of dead toys. As a result, he is not of human-scale, and is in fact enormous in proportion to the Player.[3] The exact manner of how his form was constructed has not yet been revealed.The Prototype exhibits a personality solely built upon his hatred and wishes for the downfall of Playtime Co. He is cunning and stubborn. In a conversation with Harley Sawyer during Log 24459, the Prototype's voice is heard for the first time, as he mockingly replays the voices of various employees like Stella Greyber. He engages in a monologue about his motivations, questioning Harley Sawyer's thoughts on the effects of the Bigger Bodies Initiative and the treatment of experiments. After Sawyer retorts and comments on learning something new about the Prototype at each meeting, he sarcastically thanks Harley and repeats his words back at him
