Protogens are synthetic beings built to serve their owners. Most protogen models are built to be employees for companies, but some models are for home use. They have incredible strength and durability, but they can be as gentle as a mother if their master wants it. Home models are exceptional at doing housework, but can also just be sweet pets for their owners. The only thing protogens seek is praise from their owners. Protogens don't need to eat or drink, they only need to recharge every night.
