@sirawesome Yes.

So, this one gives the new bodys, but still allows the original heads?

@alphapotato33 it says on the wiki here is the thing

Official introduction

The Glitch were part of a program invented by an unknown race of enormous intelligence, they were built as a means of simulating the social and technological progress of a civilization.
These experiments took place in a vast number of regions across the Universe, despite changing a plethora of variables each civilization eventually destroyed itself when its technological progression began to overtake its social progression. All but the Glitch.
For reasons unknown a fault caused the Glitch to become stuck early in the simulation, where they now remain. The experiment long abandoned, the Glitch are unable to shake their Medieval values and beliefs. They’re entirely unaware of their origin and are built to experience the feelings and desires of any other sentient organism.

Cool. Reminds me of Metropolis.

the glitch look like trash because they are meant to have fake skin over their body.
like on some of their clothes there is fake skin

also they could have bean built thousand of years ago at the same time humans where in the medievil age (we will never know)
