Three years ago, Special Weapons Division deactivated a highly advanced Superweapon: a 200-foot tall DNA Droid called X66-7 or "Kodoja", it was shut down because it performed too well in testing to the point of being unstoppable.
In the previous series, Kodoja was reactivated without warning and cut a swath of destruction across America, leveling every outpost of Special Weapons Division, save one. That one surviving outpost was headed by demoted chief designer of Kodoja, Jennifer Cruz. With all of Special Weapons Division gone, she and her team rushed to stop the weapon they themselves designed too well.
Kodoja was defeated in the previous arc, and now it's awake again and it's up to the Special Weapons team to stop it and the strange giant monsters fighting against it.
