The 2nd Super Robot Taisen OG introduces characters and mecha from Real Robot Regiment, the Lost Children manga, and Super Robot Taisen series MX, D, and the anime series Super Robot Taisen Original Generation: The Inspector.
All of these units clash on Aidoneus Island, which is where Meteor 3 landed many years ago. A special squad trained in ISA tactics (blitzing the enemy with battleships acting as aircraft carriers filled with human-like weapons aboard) acts under the commander of the Earth Federation President. This secret squad is codenamed "GS."
Independent from the Earth Federation Army, this unit is sent by the president when military problems arise. Under the command of the President’s two aides, Aidoneus Island has been refortified and the home of various projects and new weapons. "GS" is said to be a place for experimental weapons, but its true purpose has been kept a secret.
