>>39549215Dark Matter wasn't literally matter it was the embodiment of hate, pain, anger, ect. The marble was just a physical form not actual being.
Remember skin of evil, that black tar guy? That's basically what dark matter is. Even if you destroy the essence what it is lives one, The partner however basically destroyed it with no hate so like a clam needing a grain of sand to form a pearl, dark matter didn't get that grain of sand so can't come back.
Anyway Arceus couldn't get close to it, the only reason the player and partner could was they were wearing the harmony scarfs and the tree of life was consciously protecting them otherwise they'd be turned to stone instantly in its presence because its sucks the life energy out of everything around it.
