The old answer would have been ‘nothing’. Having seen the need for making the terrain work for you no matter the location, the Khumeia class mech was developed. It houses a device which can de-construct matter and then reconstruct it into other shapes and densities, enabling it to turn trees into shelter, stones into walls etc. as the situation on the battlefield demands. Due to the seemingly magic process this mech can perform, it is often referred as the “Alchemy mech” also,
In theory the de-construction process could be used on living tissue also, with horrific consequences to the victim. Which is kind of what happens in En-Mercs when the Artificial Life ‘liberates’ the mechs.
I this scene we can see Destrato facing off against the Khumeia mech, and whilst Destrato isn’t too phased by normal physical damage he’s not keen to find out what would happen to his body if put through the device!
