He asked Eggman what he wanted, and he claimed he wanted them to surrender to the Eggman Empire and make no attempts to resist, or his country would seice to exist. Sonic and Tails then got aboard and Tails traced his signal to the Space Colony ARK, leaving the President stunned until his secretary told him they were recieving a signal from their agent, who they had sent to retrieve the Chaos Emeralds.
Later, the Black Arms attacked Earth. The President send all his troops out and told them never to surrender. However, Central City was invaded by Black Doom and was destroyed when he took control of the Eclipse Cannon. The GUN Commander managed to get him out to the GUN Fortress before this, and he watched Gerald's broadcast. After Shadow destroyed the Black Comet, the President said to the commander that they were all wrong about the professor and decided to work to ensure peace and prosperity for a brighter future.
He also sent Rouge out to study Emerl and was mentioned by Shadow as rescuing Rouge was "a request from the President".
