It is not a flesh marauder. It is a ravager. But ok, sure. Oh, and they can infest machines, it's just hard for them to do so, and it takes a lot of flesh, work and time and the machine must be subdued or willing to become infested. Regardless, machines cant be eaten and that party is searching for food, so they will leave him alone for now. They are just looking for him, but they will not care too much about him when they do find him because he is robotic.
