Arch Enemy Of Gamma Guy: Dark Matter

I had to make a villian for Gamma Guy, so I came up with an idea of Dark Matter. Dark Matter is unknown force pushing space farther and farther away from each other, and in this case, it's Gamma Guy's Evil Villian. Here is a picture of Dark Matter:
Dark Matter wears an all black and gray uniform. He carries a shield with large spikes in his right hand, and can shoot an unknown substance out of his left hand. He has the ability to breath in other atmoshpheres besides Earth, and is protected from the vacuum of space by his helmet. Dark Matter is truley a villian to be afraid of!
