Samuel (also known by his number) was a genetically engineered worker, in the book "the eternal war".
He was described to be the size of a child, with a proportionally large head, with a lipless mouth, a hole for a nose, and eyes the size of pinpricks.
He was grown like a plant in a factory, but was much smarter then most other genetically engineered workers, and even learnt to read. When he tried to start a strike, he was punished, so he escaped with other workers, and became the leader of a band of escapees. He captured Abraham Lincoln and Sal, who were the first humans he met to treat him like a person. Eventually, he was shot, along with the rest of the escapees.
