Vox and Diona don't have blood
Created by: Probe1
I seem to remember them having blood at some point but they sure as hell don't now. It's one thing for skeletons and plasmamen not to, that makes sense, but this is a bit silly.
Now you could add blood in for them and be done but if you really wanted to do the job right, you would give them different blood than humans. Whereas iron increases a humans blood regeneration rate, copper would do the same for Vox and plant fertilizer would do the same for Diona.
