As opposed to a Ghost Mabel or something? I sort of agree but I didn't make it up. It mostly seems to have started for what looks cool for fan art, though since most of them are supernatural I don't know who decided she shouldn't be, I guess Evil Morty also isn't supernatural.
Despite all the weird spanish videos and edgy fan art I don't get the plot or if there is one, why would these characters be friends? They're evil and shit. Or do they all fight each other to the death? I don't know.>>99858852
Actually pretty cool and makes sense. She was a villain in the original draft just like the original story after all.
