You seen the iron man fly in the sky, out of space and pass through narrow pathway. In this movie, you even seen a juggernaut size / type of iron man crashing through walls without a tiny bit of problem. But there is this seen where the iron man sinks down the sea, caught within the rocks and cave in. That's the end of the trailer. My type of iron man suit is one of those that can dive deep into the water, withstand any sort of water pressure and, of course, it does not rust as well. It allows you to move and glide in the water very smoothly. Instead of bullets since it does not work inside the water, it shoots out a laser beam which cuts anything. Some sort light a lightsaber. It also shoots torpedo in a very high speed to destroy any hard objects like submarine. It also can create a water shockwave to determine the distance from the enemy or as a weapon. Overall look, the suit must be in blue colour. It works as a camouflage inside water. Also, the suit does not produce any heat and sound, therefore, it is undetectable.
