Chou Super Robot Wars Æ
In the future, a coup d'etat in the Martian Union led to the overthrow and foundation of the Martian Empire, a puppet government in Mars under the control of the Jovian Dark System, a collection of colonies controlled by the Decepticons, malevolent machines from another universe, and ruled by Megatron's loyal servant, the Viceroy of Destruction, Soundwave, as the Jovian System's Governor-General.

The Martian Empire fought against the United Earth government in a two-year war that ended in an Martian victory and occupation of the entire Earth.

The young Akatsuki is involved in the crossfire when he gets sent to the past and to another dimension to avert the crisis that troubles his universe. From there, he becomes a loving friend of the Autobots, even befriending fellow Autobot, Hotshot.

Later on, it is revealed that Jetfire retrieved the inactive ASW-G-08 Barbatos from Akatsuki's universe and had it rebuilt into a newer and much more powerful version: the ASW-G-99 Hercules. Throughout the game, Akatsuki pilots the Hercules to assist the heroes and the Autobots in the battle against the Megatron-Belial Alliance.

Trivia

 * Though his machine, the ASW-G-99 Hercules is a rebuilt and upgraded form of ASW-G-08 Barbatos, it is created by Banpresto exclusively for Chou Super Robot Wars, technically making it a "Banpresto Original" mecha.
