Walter is the second of the two robots in the team. He is equiped with a flying device. These are two static wings attached to his back. They use some kind of jets I guess but I am not sure. He is able of using his wings to attack criminels. He throws them away. They are then capable of flying along the way without his help. Sometimes he carries his team mates through the air if there are places not to reach. Biker is not very keen of flying through the air and they got some quarrels because of this topic. He always had the fear that Walter could drop him accidently.
Walter is a character which loves children very much. In many episodes the children went to him. Perhaps they liked him also because he is a little bit foddy but not much. In one episode he had to detach his arm from his body to save a children. He can really good get on with them.
