Soundwave analyzed all the newcomers. His visor displayed a circular cursor that moved over them one by one, assessing what weapons he could see and comparing them to ones he knew. He immediately entered a defensive state when he noticed the blue box appear. It's technology level seemed to be equivalent, if not more so, then his own. Then one of the humans started shooting. After identifying the weapon, he deemed it to be of no major threat. It would not have enough power to break his armor. However, there was a greater threat then the human with the gun. The machine that had appeared before them in a form of a blue box was a threat. His scanners started to attempt to peer inside the box, seeing what weapons it might hold.
