Homebrew Electroid Species Details
When a sentient robot is created, they typically already have all the mental faculties of a fully grown adult, and they know nothing they weren't built to know. In addition to this, they don't often get the chance to experience the world for themselves. The combination of these factors can be a dangerous mix, as a robot won't often get the chance to question anything they are told, and will believe it wholeheartedly until they see any evidence otherwise.
Humanoid robots have a range of appearances, some appearing almost like mechanical skeletons whereas others are nearly indistinguishable from a human being.
They may be designed to exhibit particularly feminine or masculine features, although they are generally unconcerned with such matters themselves.
Robots do not age like biological creatures do, although they may suffer wear and tear over time. With proper maintenance, robots can be theoretically immortal, though they still run the risk of having their processing unit destroyed, which would result in a permanent and irreversible death.
