You decide on some random element you find in the list as well as a duration of 2 hours. As you press start a message appears on the screen of the device telling you to disrobe. You and the machine are in a separated booth at the store so you lock the door and get out of your clothes. As you put your hand back on the device it seems to be held in place by the machine.
At first your feet start to change, your toes combine into one mass which bulges out turning into what appears to have a golden metal surface, the rest of your feet turn to a matching dark grey mass as the soles of your feet turn into sturdy rubber soles, after a few moments your lower legs become wider turning into the same material as the bulk of your feet. Just below your knees golden rings appear on the rims of folds which seem like the end of the boots that were once your feet. However unlike wearing boots you can still move them easily even wiggling your toes bends the boots, strangely you can still feel the carpet below you.
Then you notice that the skin on your legs has changed its colour to pale blue, as you touch it with your free hand you notice that it seems to consist of overlapping metal plates covered and connected by leather. On your knees patterns of plates form, seemingly to allow movement of them without sacrificing protection. Your attention moves to your member which, from all the excitement it was already fairly erect. You start to stroke it and shivers of spasms run though your body. Suddenly you reach the peak and a metal blade shoots out of it. The shock causes you to let go of it and moments later you hear a loud clang as it falls to the ground. Looking down you realize that it has now become a sword and your crotch has sealed up to the same hairless leather as your legs.
As the leatherisation reaches upwards it creates a red ring of leather forming into a belt, separating what now looks like a pair of trousers from the rest. Above it your skin turns azure as it turns into leather. Feeling around it you notice the same construction with metal plates as in your legs. On your front two rows of 5 golden buttons emerge from the leather which also spreads over to your arms. Some changes seem to happen on your back, shifting your weight considerably, but you are unable to make them out, except for a sleeveless coat emerging from it. As the leather reaches your hands, another colour change takes place changing them into bright red and causing a fold to appear making them look like gloves. For a moment your vision is gone and you feel a bit uneasy as something is happening to your head. Suddenly it all stops and the machine releases you.
You look around you and suddenly realize there is a mirror hidden behind a curtain. As you open it you get the first full glance at your new body. You might be mistaken for a biker wearing a fairly colourful set of leathers if it wasn't for the sword for which you realize a holster has formed on your belt... and what's on your back. Looking at it closer you realize that it's a large jet engine with telescopic wings to the side. Suddenly you find that it's actually easy to extend them and it seems like you could even start the engine, which might be a bad idea indoors. Your also appear to wear a helmet with a visor and as you open it, a hole stares back at you. Curiously you sit down on a bench and lay one of your legs on top of the other. Despite seemingly wearing a tight set of leathers you are able to move rather well. You start pulling on what looks like your boot and it comes off. However instead of the usual foot there's nothing in it, in fact as you reach into the stump you realize that it is completely empty, yet you can feel your fingers from inside of your leg. You put on your boot again and try the same thing with one of your hands, it too comes off leaving nothing but a hollow stump behind.
