There are also several unused lines, fully voiced by the game's English cast. Notably, some of these lines hint at scenes removed from the game's Last Story, 2 of which featured the President and his secretary, the latter (as well as Amy) telling the President not to give up hope and a scene that would take place shortly after Finalhazard's defeat, where the President says that, as a child, he admired heroes like Sonic and aspired to be as heroic and beloved as him, with the Secretary offering encouragement.

Another set of lines that would have appeared during the ending credits feature Eggman declaring he'll conquer the world without anyone's help, as well as him and Tails agreeing not to hold back next time they meet.
