I really should torment some other DC superhero, but there's just something so fun about Superman.
----------
It is called a molecular resequencer, Superman. The clue is in the name. Kryptonians may be powerful but, as you are discovering, they are still very much made of molecules.
You have the honour of being its first living test subject. I can only imagine the sensations you are experiencing as your atoms are realigned. As your joints harden. As your strength fades.
When it comes to turning complex objects, like a man, into simple ones, like plastic, there is nothing the device can't do. Although I'm afraid the reverse, turning some crude mannequin back into a man, is quite beyond the realms of physics. Even my genius is still a slave to entropy, Superman.
Not long now. In a few moments, you will be nothing more than a perfectly ordinary, mundane mannequin, down to your very atoms. Existing to model the latest fashion and nothing more. A rather insignificant end for such a powerful man.
If it is any reassurance, nobody will ever know.
