In a yapping mood, what if the reason Vesper consumes Z crystals is because they themselves does not produce enough of it? Not like they can control the fact the z crystals just crumble in their hands...
So they can't even use a Marshadowium Z either. However.... What if their aura could flare to life like the Totems/UBs/Necrozma when met with a life or death situation? I do not think normal marshadow could do that, again unless they're a totem.
This leaves them susceptible to Spectral Thief though... Which like rip if they're slower lol
Scrapped this, it is literally just vampirism genes now in a nutshell.
Doesnt elaborate
