Picture of him on at the bottom
Alex is made to look about 18, but he is around people of all ages. He doesn't judge people by their looks, or doesn't judge them at all. He is fun to be around, and can be a bit goofy at times, but most of time, he is cool to be around.
Alex was made in Freddy Fazbear's pizza for the children to be around, and talk to. Them made him look like a human, so the children won't think that he was like the others. After a while, he was discontinued and put in Parts and Service to rot. Alex wasn't going to let it happen so he ran away from Freddy Fazbear's Pizza, and hid himself from most people, except his friends that he can trust.
