Yes, you could Pharoah. Though, I'm not sure where he would find them.... Since this is a convention, I'm going to be throwing out 'speeches' the company is making about their products, so if you have ideas, I can make them give a speech about one object or another. Then... when something happens... our characters can gather up some of these items, and use them to fight. :3.

As for the fourth dimensional travel, it is not exactly instant. They move much faster than normal, and use their movement to make extremely hard to predict movements. Since they can move unlike we can, they might take a single step behind them, which might take them to the ceiling. Not right behind you as they'd like, but you probably wouldn't have known where they went. They would then be able to make a few more steps in other directions, and soon reach behind you. Since our characters will be stronger than normal, they will probably learn about these abilities, and learn how the monsters use them, and use them to their own advantage. It won't be INSTANT teleportation, and it's not exactly accurate, but it's pretty dang hard to hit something that has no pattern. And since most people wouldn't be able to see it.

as for the how this technology would be invented one idea is demolition by using sound waves one guy could knock down a hole building in about a minute with no explosives the building would just collapse so it would be quick, easy, safe, and thanks to the quickness and ease of it it would also be cost effective as just with one set you could knock down as many building as you want. The potential they would have as a weapon would also mean you could explain it by the military contracting you to build it as a weapon.
