Soundless
Soundless(minor) by Mr. Twist
You create absolutely no sound. Basically, you can't be sensed by auditory senses of any kind. Sonar can't pick you up either for some reason. This extends only to you and things your personal equipment. If it leaves your hand, it makes whatever normal sound it would create. Large weapons, like machine guns, are only partially muffled. They make only a tenth as much noise as they would normally. Of course, you must be able to hold them and fire them in the first place. Other weapons, like rifles on down through pistols, make no sound from being fired. The only sounds they would make would be from the bullet passing by or impacting something. This power also completely muffles any sound you would make by crossing, at any speed, noisy ground. This does not have any affect on vehicles you are in, though skates and skateboards may be silent at GM's discretion.
