Droid (Earth-2042)

"You're just a droid. You don't know about real duty, about what it's like to have a brother. I am sorry. I always wanted to have organic feelings, but I do not."

- John-117 and 343 Guilty Spark

Droids, less commonly known as robots, constructs and automatons, are mechanical beings that possess artificial intelligence. They are used in a variety of roles and environments, often those considered too menial or too dangerous for other species, but also in fields that require extensive specialization and knowledge.
