The I.O.N. Cannon

I.O.N.: improved omnipowered nova-blaster. Story: you found a very interesting object in you grandfather’s closet, you opened its case, filled with dust, and when you figured out how to turn it on, it locked onto your arm. It has chosen you has it’s user, and now you have to explain to your parents why you have a dangerously overpowered device on your arm. Good luck!
