After a huge power blackout across the Pacific Northwest with an electromagnetic pulse occurs, word of the incident soon reached the Pentagon. During a joint meeting of the top brass of the United States military, Commander Walters though that they need additional help to investigate the incident. He suggested calling on Dr. Robotnik, despite concerns from the Joint Chiefs, especially the United States Air Force Chief of Staff, due to past encounters with the doctor. Despite their concerns, Walters told them that they had no other options but to consider him on the matter, though the Air Force Chief of Staff spoke for everyone saying that he could not believe Walters was going to bring Robotnik into the situation.
After Robotnik's disappearance, Walters came by the Wachowskis' house in Green Hills. He revealed that the Pentagon had erased all information pertaining to what happened with Robotnik, Tom and Maddie, and that they were not responsible for it. He then rewarded Tom and Maddie for their part in keeping things under wraps by giving them a gift card to Olive Garden as thanks from the U.S. government. He then asked if they knew where the alien had gone to, even offering him a chance to meet the President, before Tom and Maddie politely closed the door and sent him on his way.
Commander Walters is a serious man who holds a position of great trust in the United States Armed Forces. He is willing to take risks, calling in Robotnik to help investigate Sonic's EMP despite the concerns of his comrades. However, he is not a stern individual, and was very warm with Tom and Maddie. He can be a bit awkward though, as he tried a little too hard to keep them from closing their front door.
