However, you could create possible things which quantum tunnel and then bind together. That's extremely overpowered, and renders any form of armour at all irrelevant except for electromagnetic, or gravitational, armour. You can break through any sort of matter at all, and do whatever you want.

The only two things you can't do are influence gravity or electromagnetism, although theoretically you could create an entirely massive object and influence gravity, or an electromagnet and influence electromagnetism.

So, actually, there's technically nothing you can't do that fits within the bounds of physics.
