Long before the term science fiction was coined by Hugo Gernsback, robots were showing up in stories. The idea of mechanical men goes as far back as at least the story "The City of Brass" from the collection of Middle Eastern folk tales One Thousand and One Nights. In the centuries that have passed since then, robots have become stranger, bigger, cooler, and stronger, and Marvel Comics has played a big part in the world's growing love for robots over the last 80 years.
