Speedy Duke (Duke or Duke)

Duke was passing by the main square; everyone looked at him with distrust and a slight sense of fear after that incident with the virus.
Duke is a kind and quiet robot-train who tends to avoid socializing, and he didn't like working with others, but he is respectful toward Kay, Jeffrey, and other authority figures. According to Duke, he spoke kind words and never hated anyone. However, according to Victor, while under the virus's control before the opening ceremony, he suddenly injured other trains and almost attempted to destroy Kay's magnetic engine.
