So like the power would just be the effect of outer space. Like the character doesn't need to breath he can just erase things like say there's a room full of enemies he can just erase the air from the room causing their lungs to collapse before air can come in from the cracks of the door to save them. He can erase friction, and gravity on himself to allow him to move in a straight line as fast as the kinetic energy propels him forward as though there is nothing stopping him in straight lines infinitely. At first he can erase or push things aside 3 things at once, he'd be hard to hit with solid objects, as he has gravity and friction turned off on himself so touching him with a solid object would just push him in a different direction essentially absorbing the blow instead of blunt damage or stabbing as it would be like trying to fish a piece of cereal out of a bowl of milk with a knife your not cutting it or picking it up your just pushing it around. He can erase all states of matter except living things, so no animals, humans, or plants. But things like water, air, stone, metal, plasma concepts like gravity, friction. What do yall think? Is there a way to make it better? Other things he can turn to nothing? Essentially breaking the laws of matter, meaning something can't change how much mass unless it's a chemical reaction.
