The Commander

The GUN Federation's highest ranking officer, the Commander (also known as the General), who first appeared in Shadow the Hedgehog, is described as having a "heart of stone", he has complete confidence and an iron will. He appears in several cutscenes in the game where he is seen ordering his troops against the Black Arms and Shadow. He also controls the Diablon robot, one of the final bosses of the game. It is not seen if he is inside it or controls it remotely, but since he is in the GUN fortress after the Diablon robot is destroyed, it is more probable that he controls it remotely.

The Commander grew up with his family on the Space Colony ARK, and was a good friend of Maria Robotnik. However, he saw Shadow being created by Black Doom and Gerald, and his family and Maria were later killed in the GUN military's attack. He harbors a deep personal hatred towards Shadow the Hedgehog, blaming him for their deaths, and sends his forces to destroy him throughout the game. The Commander appears to have heterochromia, as he has one blue and one amber eye.

After Shadow defeats Devil Doom and destroys the Black Comet, the Presidents states how ironic it was that people treated Gerald like he was evil, and he ended up saving them all in the end. The Commander and the President realize they were wrong about Gerald's intentions and that he was truly a good hearted person. They decide they will help create peace for the world in honor of Gerald. In the Expert Mode, it is revealed that the Commander had become a grandfather one week after the events of the game and invited Shadow over as part of his apology to the Hedgehog.

He will be appearing in Sonic Chronicles: The Dark Brotherhood.
