Robots are a type of enemy in NieR RepliCant and NieR Gestalt (NIER). They can be found in the Junk Heap. They come in several different forms, like flying, humanoid, and ground robots.
They were created by humans ages ago to protect the Junk Heap, which used to be an army base. Kalil forms a friendship with the humanoid robot, P-33, and calls it "Beepy".
