Grimm can't use Dust and don't have Aura. They don't need to eat and leave animals alone most of the time. They hate humans and faunus and try to kill them on sight. All they care about is learn to kill better trying to stay alive. They vanish is smoke particles and and ash when they die, melting away. Grimm were seen born or being remade or ehance in pools on the ground around Salem's summer home. Grimm are drawn by our darker emotions and thoughs like greed, hate, fear, jealousy.

Dust uses elements. Dust also vanishes on use. Dust, if not used, will remain, so in a way it doesn't need anything to feed off of. Humans and Faunus use Dust, not animals. When human uses Dust its often in battle but also in daily life. Dust is mined from the ground. Dust can be put into the body, into clothes, into weapons, or used as ammo.

"Despite its widespread use and prevalence in society, humanity has yet to understand the origins or the implications of their involvement with Dust." It's this quote that I keep zero-ing in on. We don't know much about Dust or Grimm. And both vanish as soon as they're used up. And but come up out of the ground. And Grimm destroy things people create. Is it possible they are attacking them because of the Dust used to make these structures? Or maybe because dust is used to run the structures? The implication that Grimm die with locked up if they can't feed off negative emotions or act on their killing instincts vexes me too. I feel like they're programed. Like they're tools forced to follow a prime directive and if they don't the cease to exist.
