The Commander is a long time supervillain known for testing the limits of superheroes and generally involving himself in nefarious plots ranging from the theft of experimental technology to the subjugation of urban centers. He has attempted to take over Liberty City on numerous occasions. Although Captain Thunder and others always overcame the Commander, they have never managed to hold him for long or expose his true identity.
The Commander controls a highly advanced powersuit of possible alien origin powered by a strange glowing crystal embedded in the breastplate of the armor. It grants him the powers of flight and teleportation as well as the ability to control any and all electronically controlled machinery he can perceive. He also wears a cape.
He is considered a world class threat and wanted by several sovereign nations for crimes against humanity... including the United States.
