Detailed information:
The soul is the pilot, the brain is the cockpit, the bones are the skeleton of the mech and the flesh is the actual mech with skin covering/armor.
The eyes are camera lenses that the soul inside of the brain sees through, the mouth is like the fuel filler port on a car, the butt is an exhaust port, the organs inside the body are machinery (the circulatory system is what keeps them functioning, with the heart being the engine and lungs being one form of way to make sure the body mech is functional since mechs need a lot of energy) and blood is basically the oil.
![GM chat | Of you think about it, you're piloting a mech. You're technically just a soul, in a brain cockpit, piloting a bone mech with skin armor. Damn... I've been alive [REDACTED] years and I've never even thought about that. So... if I'm a robot... what would that make me, Ove? Oh, you're just a traditional mech, but on autopilot. *Both having an existential crisis* | image tagged in 4 undertale textboxes,undertale text box | made w/ Imgflip meme maker](http://i.imgflip.com/90h243.jpg)
