So let's assume somebody has control over all physics. This person, let's call him David, is effected by his own physics. I'm currently writing a book based on the Half-Life series, and with the focus on physics, there is a person in my book with control over them. How would you possibly defeat this person?
David effected by his own physics David has control over all physics How do you beat him? Trying to fire a gun at him? He just increases the air friction to stop it.
Edit: Yes, this is theoretical. He has control over these 'fundamental laws of the universe', and he can simply "increase the air friction". If he changes the laws of physics in one instance, then he changes it everywhere, for example, he can't just suspend an object in air because "this area has no gravity", everywhere has no gravity now.
Edit: For my purposes, any changes to physics don't violently explode the earth for example; Removing gravity doesn't explode everything. My book has three characters, which have control over people's vision, control over physics, and control over time. This character can control physics, and with the snap of a finger, Poof, there is no gravity. They are confined to a classroom, with guns, tables, chairs, pencils, everything you'd find in a classroom, but nothing else is there. How do you defeat this person who has control over physics?
